I bought my Diamond Monster 3D card (3dfx Voodoo) after I saw Quake and Tomb Raider running on it. Both games were running at smooth and stable 30 fps at 640*480 resolution, which was unheard of at the time for what was considered a high resolution back then. I had just bought a Pentium 200 MMX with Matrox Millennium 2Mb and it was considered a very good modern config for games and I still had to play both Quake and Tomb Raider at 320*200 to achieve smooth performance, despite both games supporting 640*480. So when I saw in a computer shop how great 3dfx runs both games in hi-rez and with smooth filtered textures on top (I actually loved bilinear filtering at first sight back then, because I was never a fan of pixelated look), my mind was completely blown away. I instantly realized that this card is exactly what I needed in life ASAP! Had to borrow money from my parents instantly (they bought me my Pentium computer, but didn't approve buying additional games-focused hardware, so this I had to work for afterwards, but it was totally worth it lol).
Really cool video. I still remember when the Voodoo entered the market and how stunning it was to have 3D hardware acceleration. Those were exciting times with major advances every year or two.
Couldn't agree more!
Just like today with AI
So, it’s going to be a series - ‘the quest for extra memory benefits’. Excellent, I love it already! 😉
Gotta love the Matrox + Voodoo combo. The best of 2D and 3D!
I was the first person I knew to have the monster 3D voodoo 1. I was amazed how much better my pc at the time ran quake. I was so addicted to that game back then. Quake, quake2, forsaken, unreal and unreal tournament were my crack back then… fun times.
Forsaken was great. Same as Terminal Velocity or amazing Descent.
Ziomek z osiedla miał jakiegoś biednego PC i na urodziny czy coś dostał akcelerator Voodoo i pamiętam jak chodziliśmy do niego grać w Quake na 320x240 - zapierdalało to i wyglądało cudnie! :-)
Loved my Canopus PURE 3D II 12 MB -- thanks for a great birthday, Dad
I still remember the day I bought my first voodoo fx banshee card, right when they came out. As a student i had no money for a month after but that card was worth every penny!
Man i still remember when i got my 3dfx voodoo card, holy cow, when you were used to playing with 15 fps and then suddenly quadrupling your fps.
Hah! My first foray into 3D accelerated graphics was a Voodoo3 2000. I still had my Pentium MMX 233 but no accelerator card. played all that time with software. Playing QuakeCTF I had gotten use to how it looked but with that card? Holy moley the people have faces now! Haha... ah it was such a great time.
It's cool to see the benchmark differences between the V1 cards with 4, 6, and 8 MB of memory!
I'm sure 3dfx at the time were targeting a minimum of 30+ fps. The V1 chipset is only capable of staying consistently above 30 fps at 640x480 resolution or below due to it's raw pixel fill-rate of 50 megapixels per second. There were some custom V1 setups that used SLI but they were limited to specific arcade machines or super expensive cards from Quantum3D like the Quantum3D Obsidian 100DB-4400 which was reportedly $2500 in 1996!
The Voodoo 2 was where 800x600 became the standard with 1024x768 possible in SLI mode. Mostly due to the extra RAM and the base V2 had a raw pixel fill-rate of 90 megapixels and a 2nd TMU for games that used multi-texturing like Quake 2 and Unreal. In SLI that 90 goes to 180 which is enough for smooth 1024x768 in games that supported it.
I ran glQuake on my Voodoo 1 at 512x384 to hit 60 FPS as much as possible. With the Voodoo 2 was able to go up to 640x480. I still have the batch file and glQuake settings I used backed up a CD so it wouldn’t be too much trouble to dig them up.
there was a quake voodoo fanatic at my university who in late 1997 got his Pentium MMX 166Mhz rig up to 1600x1200 at 60fps for quake using an absurd custom voodoo setup. The ultra high res CRT monitor alone must have cost him thousands of dollars, guess the total was around ten thousand $.
Wish I could have found him in 2001AD or later and asked him in retrospect if all the money and time had been worth it.
@@plasmaastronaut wow.. just wow.. i dreamed about many thousands fps quake machine in 2012 having phenom 2 955 and struggling to get 770fps rock solid with dynamic lights enabled. Now i have 4000 fps and iiyama vision master pro 514 and play occasionally..
I love this type of stuff. I was a PC hardware person and built my own PCs in the late 90s early 2000s. I had a Voodoo 3 and a Voodoo 5 card back then. Testing older games out to see how they would run at higher resolutions with more RAM and power is a nice test. Most of my games now if I get them to run on my new PC I go through the game files and put the resolutions up to 4K just to see if they would look so much better and run with higher FPS then when I used to play them. I love testing things myself.
Thank you for the boost :)
Been working on a port of this game for ages but new problems just keep cropping up. Happy to be reminded of why it's worth the effort.
I recall launching Quake II in 1920x1080, and was amazed how sharp everything is. It only gave 1 frame per 5 seconds
Lack of Performance is likely why 4MB FBI cards never saw a retail release. Only 1 4MB TMU card was released and it did show benefit in more extreme situations like glquakeworld with lots of players (each player would have a uniquely coloured skin that needed it's own texture, the 2 mb cards would texture thrash without reducing player texture quality)
Actually running these tests with a multiplayer demo instead of the classic built in demo would be quite interesting.
Yes but the Rendition Verite 1000 (4MB) 2D/3D card was released ~9 months before 3Dfx Voodoo 1. The Verite 1000 was limited in 3D resolution as some memory was kept for 2D and it was only ~66% as fast as Voodoo 1. But in some games like Tomb Raider 1 it looked better than Voodoo 1, until 3Dfx got driver tweaked better for it. (Wow heavy views on this youtube already by us old gamers 🙂 )
I was 15 or 16 years old when I bought voodoo with 4mb. It was a rainy day and I was driving my moped. It was so windy that I could only go about 25-30km/h. And in my backpack there was a brand new voodoo card. Luckily it didn't get damaged by the water. I installed it to my pentium 133mhz. My dad was watching nearby and he was a little bit nervous cause this pc cost him a really big money. "Do not fail" he told me with his eyes. I was succesfull and it was the day that changed my life. I have never ever before or after that experienced such a huge difference and quality change in games.
I cross my fingers for you that you will find a game that justifies your fantastic work. Thanks for the great videos.
Great video, especially the period correct config. I’ve chceck a Polish gaming magazine called Reset, issue 9/97 and there was an article about GLQuake by who we would today call multiplayer enthusiasts, and framerate was their preference. They’ve tested it on a P166 MMX with 16 MB of RAM and a Monster 3D. 512x384 with some details turned off was their preference (they’ve got around 50 FPS compared to 30 FPS at 640x480 with full details on).
This is also why I’ve decided to not take the „upgraded” voodoo path, since higher resolution on a Pentium would bring the framerate to low and I would go with a plain Voodoo2 on something faster than a Pentium.
There still the option of the rare Voodoo SLI (Obsidian or their recent clones), but while Quake would benefit, I’m not sure about newer games especially Unreal.
Was the article written by: RooS ? I was participating in a tournament which this guy won, great times.
@@rochr4 It was written by YoonioR, RooS's friend. He started the Quake corner in Reset and RooS later continued it.
I love 3dfx videos of yours !
Thank you for this content, it make me feel like a child again, back to 98 when I bought for my self, first Voodoo Banshee (not so best one edition) and went to the new dimension !
You're welcome! Happy to hear that the video made you feel like a child again! It was a great time to grow up during that time. Thanks for watching!
Made the same build as you, MMX 200MHz @ 250, Matrox Millennium II, Voodoo 1, 64MB PC 100, not the fastest but a good build from early 1997. Good video.
With that system even many games from 1998 run very well.
Wow, another useful video, keep it up...
Man this takes me back!
Wow cool stuff, always wanted to have a voodoo card, nice seeing these types of experiments 👍
Like! If there is a performance difference between the 4 /6 /8 mb versions, Unreal and Quake 2 surely will show it.
If there's one game that should benefit from the extra texture memory it's Unreal.
My Diamond Stealth II 4 MB ran verite Quake (VQuake) very smoothly. Next card was a 16 MB Voodoo Banshee which could run GLQuake. I did overclock the verite card (after I had the replacement) to 72 Mhz from 40Mhz, after adding heat sinks to the VRAM and a fan to the GPU. Good old Radio Shack! The bad thing, I used superglue! Whoops! I took the +80% o/c!
Great video. Please post more content like this.
Cheers
Thanks, will do!
relly nice, i honestly prefer the software render aesthetics. but the smoothness is just so good.
Thanks to Quake I upgraded basic Amiga to PowerPC one (with 220 mhz PPC card) so instead 9fps I could play in HD res in 50+fps in 2000's :)
Just watched again this video for the second time, I also watched it when it was released.
I have to say this: I really like how you present things, when quake was released I was 16... playing it at 25-30 FPS (320x200) seemed very smooth to me, and even in high resolution, at 15 FPS it was ok. Now kids say that anything under 144 FPS is unplayable...
Thank you! I agree with the low frame rates - it just was part of the games back then.
I think those brightness inconsistencies between resolutions were the reason why many monitors with a rotary encoder for the OSD would adjust the brightness directly by turning the knob without first having to press it to enter the OSD menu and select the brightness option, emulating the analog potentiometer used on older monitors.
The buttons only ones did something similar but it was not so easy to change the brightness accidentally because the buttons were smaller and a bit harder to push and sometimes hidden under a cover, while in the rotary encoder ones sometimes accidentally pushing some papers against the knob was enough to turn the monitor into an X-ray machine 😬
I love this!
I played Doom 1 and 2 to death back in 1995-1998. Then I bought Quake 2. It was such a fun game. After that I got Unreal Tournament and Half-Life and gaming life was never the same again.
Excellent Video.
Thank you!
This confirms my experience with an 8MB Voodoo1 - despite having all the cpu power in the world at hand (P3 800MHz), there pretty much isn't a game that would support the now available 800x600 resolution and run it at an acceptable framerate at the same time. No wonder almost no manufacturer offered the 8MB configuration.
Great video!
Thanks!
The voodoo1 enabled quake on my 486 DX4 pc. Also played quake2 with this card.
And scored some spletter bonus in Carmageddon.
This is really interesting! Quantum3D had some cards with boosted memory, but they also had VooDoo Graphics chips in SLI (ETA: or was it just multiple texture units? Both? Maybe it was both), so they could get higher frame rates at higher res. I always wanted to get my hands on one of those :)
Takes me back to running Quake with a Righteous 3D piggy back video accelerator and a whopping 32 mb of on system memory.
I remember the system memory made a difference to performance.
I had a 6MB Canopus Pure3D up until recently but it died on me & as you’ve shown it didn’t give me anything extra in Quake but I’ve never had an 8MB Voodoo… well I have Voodoo Rushes & also Banshees but that’s cheating. 😄
The Ati Rage Pro Turbo AGP card is interesting as it is user upgradeable from 4MB to 8MB with an onboard SODIMM slot!
excellent time to upgrade to Voodo 🤩
Amazing
I would venture a guess that games which often made use of larger sized textures might benefit from the additional TMU memory? There might be less traffic over the PCI bus, since there may be less of a need to transfer new textures from main memory or bulk storage to TMU memory. Very interested to see what you test next.
I remember playing this, the Shareware version mind you, on our old HP Pentium 166, 16MB EDO RAM, 2 or 4mb integrated graphics.....it ran pretty well with minimal hesitation.
Again nice video, and interesting to see that no performance increase is noted between the different memory combinations.
What shortcutsettings did you use to swap to the 800x600 GLQuake?
I think it was just: -width 800 -height 600 -bpp 16
The height parameter may be optional and ignored.
my first Graphic card was Vodoo II 3dfx.. Thanks Baba im now getting 38.. time goes lay lay lum Damnn Fast
Oh Voodoo, sweet memories.
Maybe Descent or Turok would perform better with the added RAM? Fun video, thanks! Really takes me back to those old days.
Yes! I wanna see them charts!
Great video! Are there any earlier 3D games that took advantage of 4MB of texture memory that you know of?
Until now I have not seen any game that does. Only the "Race" benchmark in 3DMark99 does have a significant uplift from the extra texture memory.
Genuine question: does aging silicon affect the performance in any discernable way? Especially given how disparate the components used to be in older IBM-compatibles and their incessent IRQ and DMA conflicts
I don't think that aging silicon gets slower over time. Maybe there are some cases where ECC memory causes some delays when one memory cell is damaged and the extra ECC cycles take more time - or similar cases. But I think as long as the chip works, the performance should remain the same regardless of age.
When I finally caved to Mac with the M1 I got a MacMini
I was Huge Linux & Dreamcast Quake III Arena Nerd
on the M1 I have gone back and found how to use Homebrew to get it working
Now with HD Skins!
Holy Crap
From what I remember Quake just wasn't optimized for higher resolutions, on a Pentium 200MMX, at 640x480 I had a higher frame rate in Quake 2 than in Quake 1.
GLQuake might have been the best way to play Quake but it always felt off. Of course dynamic lighting in form of light balls is silly but can also be easily changed back to proper dynamic lighting. Main reason why GLQuake is less than ideal is missing feature called overbright lighting. It is ability for lightmaps to make textures brighter than texture is normally and not supporting it makes GLQuake look very flat in places where lighting normally was overbrightened. Lighting GLQuake looks at places very flat and far from climatic original creative intent. Last two things, something which can fortunately be changed is non-square texturers rounddown and texture filtering. First does with reducing sizes of non-square and non power of two size textures to lower square power of two textures - literally making textures lower resolution. This can be disabled and then we get upscaled version of textures - which while not perfect at least preserve all details and are sharper. Very last thing is bilinear filtering. I never liked this feature for games with lower resolution textures and it only started making sense in much later games with better textures. Quake like many games of the era in software rendering had nice square texels and this helped make low resolution textures appear much sharper. Doing bilinear filtering on low resolution textures creates this kinda soapy feeling. In GLQuake and other Quake engine based games texture filtering can be thankfully changed. Today we have ports of Quake and some other games which used the same undercooked hardware acceleration implementation and with texture filtering to GL_NEAREST_MIPMAP_LINEAR and texture round down disabled is the best way to play these games. As for Voodoo I never liked bilinear filtering and the only thing I didn't like 3dfx for is not giving users ability to force bilinear filtering off globally.
Quake :D :D My first real 3D game , wich I played on my Amiga 1200 ( MC68040-40MHz 64MB RAM and Picasso II+ GFX Card ) :) :) Still, to this day I like that game :D :D
I feel old
Great video though :D
Can't remember which Voodoo I had but it was a major leap forward!
This game brought a lot of PC's to their knees when it came out. I know a lot of people who bought Pentiums just so they could play this. I had a 486dx4 at the time and it would not cut it for games anymore. This game and other games like Need For Speed prompted me to get a Pentium Pro processor and a Voodoo card.
it could be the bios, or the drivers not comunicating together
That darkness bug is interesting, it has been a long time but I don't remember that from the Voodoo2 days and running Quake etc at 800x600, 1024x768 was possible with SLI cards as well wasn't it?
Maybe it's a Quake engine bug. Am I imagining it or is the texture filtering reduced in the 800x600 example as well? not sure if its just the extra pixels or if there's quite different settings running.
You can definitely run Half-Life @1024x768 in SLI.
Good question. I could try Quake and a Voodoo 2 at different resolutions and see how the image brightness behaves. I didn't change any settings which changing resolution.
At 6:40 interesting the voodoo image quality is worse than the software render but much more playable (textures are lower res and blurred out). Edit: think it may just be texture upscaling, looks nearest neighbour on software and some kind of filter on the voodoo. Though bricks when in the background look a better when further away on software render
i miss that days
1997 we were aiming for 75hz gameplay. Everyone knew how to turn on the fps counter in Quake...
75 Hz didn't mean 75 fps though.
Yes. Early 3D titles are very optimized and use as little as possible texture memory. Because it's very precious resource. And early 3D hardware had same memory sizes. You should try look at games of '99-'00. In this period games targeted wide range of 3D hardware with very various sizes of texture memory. And Voodoo 1 is not so obsolete for such titles.
i had the rival Matrox daughter card that didnt run GLIDE.. it ran an alternative API that looked just as good.. that was so long ago i forget the details.. but i upgraded to a VOODOO 2 later
Sounds like SGL API for PowerVR 3d accelerators.
Please try Half Life 1 with modded Voodoo 1 :D
Being poor and broke could barely afford a voodoo2 let alone a monitor that could give me a decent refresh rate. Most of the time I ran 640x480 at 85hz or 800x600 at 75hz. 1024x768 at 60hz was a flickering nightmare and would opt in for a smoother 85hz experience over higher resolution. It would have been nice to have a decent monitor that could do a refresh of 1024x768 @ 85hz but they were uber expensive.
i have never knew they wrote about quake in Commander keen 1. then again i never really bothered to read it. but this is interesting. so they already had this game in mind. strange that they didnt made this game before wolfenstein and doom then. would have made more sense.
GLQuake doesn't run in 800x600 on my Voodoo3 3000 (16mb AGP). Am I doing something wrong? It works only in 640x480.
Also, do you know the reason why most games become overly bright when running with Voodoo cards? It baffles and annoys me to the extent of me preferring some games to be ran in software.
I have noticed this as well. I may look into this - there are some unanswered questions. E.g. 800x600 dark colors, 512x384 bright colors, etc.
As essentially a first generation GPU, the Voodoo 1 design seems like it lacks the power to utilise much more than 4mb of onboard memory. I would presume that 3DFX would have tested this before specifying a supported board layout design. This makes sense because back then memory chips were very expensive. The Voodoo 2 could well be a better chip to upgrade as that had more than one varient in terms of onboard memory allocation.
GL Quake didn't fully utilize graphics processors' capabilities, it just treated it like a framebuffer and sent draw commands directly to the card. That's quicker, but not much.
Quake 2 actually was written so send triangles to the graphics card and let it build scenes itself, which meant it could be much better accelerated. Though, it looked awful since you couldn't do much with those primitive APIs compared to what ID could do in software rendering.
May be you should try your mod with this excellent game named Motorhead ! (Many graphic options for testing...)
Hi guys, help please. Recently I bought v1, paired with matrox millenium 2. When I tried to run glquake, console says that GL_vendor is Microsoft, not 3dfx interactive (5:51). In this mode I have about 1 fps, in menu too. My PC recognizes "voodoo 3dfx" as a multimedia card. I assume, I did something wrong, maybe wrong drivers or GL settings? :( Any ideas? I have never had V1 card till now ;)
You may have to read a bit more how to get proper 3dfx support on GLQuake. I would have to read through it again since I forgot most of it. If it's not covered in the video, then I would experiment with a few patches. It may also be that you have to rename some files for GLQuake to properly use the Voodoo 1.
That means you don't have any 3dfx MiniGL drivers installed. Install them (installer copies the needed driver files to the games folder and maybe also a C:\Windows subfolder) and it should work.
I'll always prefer the sofware renderer especially on ports. The textures were a lot more detailed, otherwise it makes the games look like N64 games, and I never liked how the filtering looked. I actually always preferred the rough render of the original Psx to the N64 games, even with the weird distorted textures.
I remember when this came out I had the 6mb glide. I remember back then you changed graphics cards faster than your drawers until the GeForce 4 came out which was odd because the GeForce 3 was better with its programmable 8 bit pixel ahaders haha
Never heard that gf3 was somehow better than 4. Only remember some bad nehavior with anisotropic filtering on non orthogonal walls.
I remember my first 3d accelerator is S3 Virge with 4MB mem, I can run tomb raider 2 pc version in 480x360 resolution very smooth. 🤣 change it with NVIDIA Riva TNT in many years latter
I always preferrde the dynamic lights of the software renderer to that crappy yellow lightmap of the gl renderer.
3:50 i don't know where you lived, but that was not at all the case in my circles. fps in the 20s were still the minimum threshold for playability. and i would 100% play this game a 320x200 in this machine, as i did in my pentium 233mmx until i bought my voodoo2 in mid or late 1997, idk. the only reason i played this at 20fps on my 486dx4 i had when this launched was because the tradeoff between screen size and frame rate reached a point where if i made it any smaller the game would be unplayable because it was too small.
Almost no games will benefit from more memory on Voodoo Graphics but in Unreal you will see a noticeable difference.
28yrs ago wow... i played quake 2 in windows 98 PC but i haven't tried quake 1 ever since... they said Quake 1 way back 1995 was the first decent 3D Graphics game no hybrid 2D and 3D graphics combine just pure 3D... unlike Doom 95 monster avatar were made of 2D and the rest of the map are 3D walls
You forgot to tell that some Quake versions for Windows has upscaling and it is turned on by default. So the game is rendered in lower resolution than you see it on the screen.
Also many Quake-versions for Windows break the gameplay. For example the Nailgun shoots from the armpits of the player rather than from the weapon. Also the secrets are shown in advance because the textures are flickering. I have heard this issue was called Z-fighting. This depends on the renderer being used.
The port qbism Super8 works more or less correctly. But the close-range melee weapons in mods are broken.
The port Tenebrae has no Z-fighting but the Nailgun is broken a little bit.
And so it is much better to play the original MS-DOS Quake with the Ultimate Regular Quake Patch 1.05 (short URQP).
6:30 how did u managed do sync everything?
When you start the game, the DEMO1 map is running not using TIMEDEMO. That means that the duration of the run is the same regardless of how many frames are drawn. Then I could just use a half of each run and they aligned nicely.
👍
I wonder if NFS5 will work better?
Any idea why it got darker after adding the extra memory?
I have not checked yet, but it only happens at the higher resolution of 800x600. Maybe there is no driver profile for brightness.
@@bitsundbolts The Voodoo card's way of saying "you are not supposed to see this"
That was a lot of heatspread jelly.....
Still prefer Software rendering =) its looks more ... juicy =)
even now, in Quake Champions i like to use DownScale resolution to make it looks more pixelated
btw, to fix Dark Quake u just need in game console command "gamma %number%"
It usally didn't work in early days and engines, you should use modiffied pallete.lmp (idgamma utility) or for voodoo set environment variables SET SST_GAMMA_RED green and blue.
I would really want to go back in time, and check the framerate on my Pentium 133 + Diamond Monster Voodoo 1, because I would swear, that Quake 1 was one of the games what were battery smooth in this setup. In 640 x 480. At the same time I know for sure, that Unreal was horrible even in 512 x 384 🤣 Also, sin was not very happy in that configuration either. Even if I changed the processor to maybe 233Mhz Celeron. I am not sure in the frequency anymore, but it was the "card" processor without any box around it (was the box for the L2 cache?)
Of course, at that time I did not give half a damn about framerates, so I am not sure :D
How about testing it with Shogo Mobile Armor Division? In that game I am very sure that there were 60fps parts, because in the very beginning I was stunned how smooth is the picture when I went in the cantine. Everywhere else it was slower, but there it became locked to the monitors refresh rate.
7:39, it says "Scan-Line Interlaved?" No. So, SLI technology was already available on Voodoo 1? Or it's just a common program for both the Voodoo 1 and Voodoo 2?
Well I just read this from Wikipedia: "However, the original Voodoo Graphics card and the VSA-100 were also SLI-capable." => didn't know!!
Yes, the Voodoo was indeed capable to run in SLI. You can google "Quantum3D Obsidian SB50-4220" to see some of those variants.
Glquake is the only way to play. I have it on a W98SE with a i233 MMX Pentium and it works great.
20frames was ok? Maybe for playing on keyboard.
i had Pentium 200 MMX, i dont remember my GPU :)
That mod is interesting. Where can I get that or learn how to make one myself?
Please wait a bit, I will bring an updated version of the mod. But if you want to know more about it, you can start here: github.com/BitsUndBolts/3Dfx-Voodoo-Memory-Mod
Hey, I just released a video with the updated version of the mod. The links how to get it are in the video description of the video. If you need any further help, please let me know!
its weird 3dfx get dark shadows.. when i had my voodoo all games i've played was brighter, Unreal Tournament 99, Quake 2, Monster Truck Madness etc..
Sounds like its almost time to add more memory to a voodoo2
So many Voodoo2 cards followed the reference design too, seems like a memory upgrade might be a more universal fit for those. Only know of a couple that were laid out differently, the 12MB cards were pretty much all the same though.
I wish i could slap some more vram just like that to my rtx 3060ti...
some errors ..
a) Quake 2 doesn't use the same generation of engine
b) the resolution could also changed before via command and before ..
c) GLQuake is an modified variant of winquake not the old original.
some other points:
why is doom recorded in low res mode?
why is the primary ask busted in the first moments?
try motoracer next please
saying tv is 25 or 30 frames per second is just unfortunate terminology. interlacing means you get new picture 50 or 60 times per second. that's the effective framerate.
