Is 8GB of VRAM Enough for PC VR?
Вставка
- Опубліковано 5 чер 2024
- It's currently October 2023 and both AMD and Nvidia have recently released what are supposed to be mid-tier graphics cards with only 8GB of VRAM on them! Namely the RX 7600 and the RTX 4060ti 8GB. Many games nowadays are beginning to recommend 12 or even 16GB of VRAM which begs the question, what were AMD and Nvidia thinking when designing these cards? They argue 8GB is still plenty of VRAM for most games, especially if you're playing at lower resolutions like 1080p (aka full HD). Well, when playing games in VR we are often playing at resolutions much higher than 1920 x 1080 and even higher than 4K (3840 x 2160) and for those that know anything about how computer graphics work, the higher you set the render resolution of your games the more VRAM is required to store textures, character and other object models as well as other game assets. Since we're playing at much higher resolutions in VR and more VRAM is needed the higher your render resolution is, this of course begs the question, Is 8GB of VRAM enough to play PCVR? Well that's what we aim to find out in this video. To explore this question I ended up testing 4 different GPU's; the Radeon RX 7600 8GB, the Radeon RX 7900XTX 24GB, the GeForce RTX 4060ti 8GB and the GeForce RTX 4060ti 16GB. While comparing the RX 7600 and 7900XTX didn't help me figure out whether or not 8GB of VRAM was liming the performance of the RX 7600, it did help me figure out which games I own will utilize more than 8GB of VRAM. I was then able to play all the same games with the both the RTX 4060ti 8GB and the RTX 4060ti 16GB and I was surprised by what I found out.

Turns out that Hardware-Accelerated GPU Scheduling in Windows Settings was causing my Oculus Link to stutter/jitter. If you are using oculus link, make sure to turn this off in System>Display>Graphics>Change default graphics settings!!!!!!!!!!!!!!!
Thx
Good tip but for flat game mods like the dlssfg mod for 30 series you need to turn it back on.
thank you thank you!~
Awesome channel! Looking forward to see more VRAM testing in flat2vr mods! Saludos desde Canarias!
Your content is exactly what Im looking for. Thanks for doing this
Nice review! Looking forward to your take on the Quest 3!
Thank you so much for making VR content!!
My 5700xt does surprisingly well in assetto corsa (non competitione), but I'd love to be able to turn the settings up a bit.
At this point, I think I'll just wait until the next gen of gpu's comes out, its been an absolute workhorse on my 3440x1440 and in vr so far.
try Alien Isolation with TAA mod for better Aliasing. My 5700 runs it in 5K at acceptable frame, awesome and dirt cheap experience. P.S. try to avoid SteamVR, it eats a lot of overhead and makes things stutter without need. OpenXR or even native VR ports show how good that card can do VR.
Just spent an hour or so watching a number of your videos concerning VR/GPU's and finally subscribing. I'm mainly a flight sim guy so your MSFS performance benchmark is most interesting. But could you add DCS to the benchmark rotation? In some ways I believe it is more demanding than MSFS and I know the DCS community would appreciate someone using it as a benchmarking tool.
Hey Maraksot, great video! Really appreciate the effort you put into pcvr benchmarking. I was wondering if you could also do at least a little bit of benchmarking in demanding VR modded games. I am building a high end pc right now just to be able to play Luke Ross VR modded games like cyberpunk, hogwarts, rdr2, far cry 6, etc. at great graphics :) I understand if it's a bit too niche for your channel, but I actually think such benchmarks would pull more views than you'd think. There barely is any benchmarking on this out there. Next to nothing on AMD cards as far as I'm aware. I think these VR mods will also prove that 8GB is not enough... ;)
Amazing content Mark! I love how you put things into VR perspective theres so few creators focusing on this, I’ve got a 3060TI with 13900k but some games are just very limited on performance although they still look great, I’m still getting a 4090 just because I want the best of the best but honestly I have been able to get around 3060 TI with no problems except missing the ultra high quality we all yearn for.
Nice card, do know that the 4090 is twice as fast as the 3060 Ti, so it's a good upgrade despite it not looking like it.
I saw you playing Microsoft fight simulator in one of the test. How does/what’s your opinion on the 7900 XTX since they’ve updated the drivers?
Tks!
Thank for this video!
When playing the adult VR game VAM, I have the MS system monitor on displaying the GPUS vram status. When the 8GB is showing to be full (I peak under the headset to watch the pc screen) I get a lot of lag. VAM actually has an option to clear the vram in game and when I do I get about 1GB free and the lag stops until it is full again. This has always lead me to believe that the vram is the culprit. I believe the games engine is UNITY which is about 80% of the vr market.
I think you should totally see about making a vid on "Is the 2080 ti still good in VR in 2023? ", please and thank you
Thank you so much for this! I’m planning a new PC build this month and it’s so hard to find VR performance info. I already knew from general gpu reviewers to avoid 8gb in 2023, and thanks to your vids I know the AMD 7000 series has issues with oculus.
Now that you’ve tried the 16gb version, do you think the 4060ti 16gb is a good choice for VR? Since its price has come down a bit I’m seriously considering it, although I’ve seen a lot of people recommend going up to a 4070 instead.
The 4070 is a FAT increase over the 4060ti, if your choosing between the 2 cards 100% get the 4070
Any chance you could do the 5700xt with the Quest 2?
I'm looking to upgrade my GPU anytime soon. I can't afford a new one but the price of a used 5700xt looks very appealing, but I don't want to have to tweak the life out of it, like I do with my 6GB 1060.
Thanks
Please, test the 7900 xtx with Quest 3 using AV1 codec.
Will you be doing RX 7800 XT and/or 7700 XT PC VR reviews soon? Thanks!
He said In a comment he bought the 7700xt and that's his next bench card
I am using quest 2 and playing assetto corsa ( ~ 20 cars drift servers ) .
Used 3070 8gb and had to turn down all in game settings to low, oculus rendering res ~ 1.2x.
Now using 3080 10gb, finally i can turn up oculus rendering to max, and in game to ~ medium settings .
So in my opinion if you want good video fidelity, you need 10gb 3080 and up.
Has much more to do with the GPU's processing power than vram...
Hey, were there any performance issues with the fact the memory bus was only 128bit? I keep looking at the 4060 series just based on cost and comparing it to the 256 bit 3060.
Hey guys I've researched on Reddit and UA-cam...and it's left me in a spin lol what would be a good graphics card to go with in a laptop for pcvr (desktop isn't an option here). Some people say rtx4060 others says rtx3060. Which would work well and is there a cheaper but better Radeon option??
My Rtx 2070 is still Rocking in VR, and not so long ago my GPU was an RX 570 8GB, the only game that resist that little card was Half Life Alyx
Yeah vr performance and game performance is very based on opinion these days, for example i like to run max settings and res everything and still have a lotta frames but i need a hefty card for that, so while I personally would never settle for a 2070 for vr, if it works for you then thats great
@@nerd20fromdiscord Personally i'd never settle for giving insane amounts of money for diminishing returns, but if it works for you then that's great.
@@nonegone7170 eh thats kinda the wrong way to look at it, first of all not every game looks the same and ultra graphics will be more noticeable on some, but in vr the graphics differences are a lot more noticeable since your actually in the game
Hi, can you please do a video comparing AMD vs Nvidia GPUs for PCVR on the Quest 2/3 in terms of subjective video quality? It would probably be most fair to compare more mature GPUs, like the 6800xt and 3080. Thanks!
Go 6800xt for VR ,Skyrim VR and Fallout VR or any ported VR games take 12 -14 GB vram , I was able to run them before with 5700xt 8gb but Got really smooth performance with more vram. If you cap them at 60 fps and 100% resolution scale you should be ok with 8 -10 GB . Performance vice neither of the card will hit 100% utilization in most game But you will max out 10 -12 gb vram .
@vish452 haha I already have a 6800xt, but I was interested to see a comparison in visual quality since nvidia is known for having better encode quality and all the PCVR on Quest needs encoding
@@vish452 Rlly? Even my old 6GB GTX 1660 TI laptop was able to run Skyrim VR decently a few years ago and my 8gb 4070 laptop runs it very easily. I do think he should still go with AMD though.
Hi! Ur stutter is
Because your lens resolution is too
High in steam
Vr for quest 2 it’s overkill u need a higher more powerful Vr headset to run at those kind of video settings - u could have lowered it to 2.5k and it would have been fine - ur jaggered edges would have been more or less the same, I
Run a RTX2070 and get no stutter at all! My graphics are amazing
With i7 9700k bought in 2019! Just MSFS and F1 2022 can’t run but it’s fine I don’t play them.
Is it possible to add il2 or dcs to your game roster?
Please!! make a video on 1660 super/ti 6gb as it's only the affordable option in asia's used market.
Please make a video on 7800xt's VR performance
Please!
Respect, man!
yeah but will the 3060 Ti hold up with a Meta Quest 3?
Best vr youtuber around the world 😊
Does this mean my 1080ti will be fine? Or will it not since it’s older architecture?
8GB VRAM works well for the Quest 3. However I believe 16GB of VRAM would be able to push it forward more.
Hi so simple question i want to upgrade my gpu from a rx 580 series to a nvidia rtx 4070 or anything similar maybe even a 4080 if i decide to save up. However im running a ryzen 7 3700x cpu and a asrock b450m pro4 (am4) motherboard which is pcie3 i got a 850w gold power supply and 32 gigs of ram so i just wanted to know if upgrading the motherboard or cpu is necessary considering the motherboard is pcie3 and the cpu isnt the best i dont plan on doing anything creative like editing i just want a upgrade to play vr on a decent vr headset like the valve index or hopefully soon to come valve index2 aka valve deckard.
I think the 3700X would still work great for PC VR. I know many people in the PCDIY community like to preach about having the fastest CPU you can possibly have but that's really only important if you're looking to get the maximum performance possible from very high end GPU's at low resolutions. The higher you turn up the resolution the more stress that puts on the GPU which in turn lessens the load on the CPU. To get VR to not look like a muddy/pixelated mess you want to run your games at as high resolution as possible, often time above 4K resolution which puts much more load on the GPU, making your CPU less of a factor. So yah, I think the 3700X with your motherboard and RAM with a 4070 or 4080 will be plenty good enough for VR with an Index or Deckard. I think it'll give you a very nice VR experience.
@Maraksot78 thank you so much for the information I truly appreciate it!!!
Thanks
Hey, PCVR is sadly neglected by most PC hardware reviewers, so this is great to see. It's a shame that AMD doesn't prioritise VR more and that headset manufacturers don't prioritise AMD. I have terrible anti-aliasing, and frequent stutter and tearing using a 6600 XT with the Quest 2 and Link cable/Airlink. Then there's the Varjo Aero and DPVR E4 which just say they aren't compatible with AMD. Shame, because I'm not fussed about ray tracing and AMD usually offers better bang for buck. I'm waiting for the Q3 launch to see reviews and get an idea of what I'll need before I jump on board. I'm expecting to get a Q3 though, already upgrading my Wifi to 6E and I imagine I'll need to upgrade to an RTX 4070 as well for PCVR. It'd be great to get some actual data on that though, rather than having to infer it from flat screen benchmarks and resolutions.
I don't have a 4070 video nor do I plan on making one, but I do have a 4060ti and 4070ti video and am working on a 4060ti 16GB video. You would have to make inferences similar to comparing flat game benchmarks but they should help give you an idea of how a 4070 will perform. Looking at flat game benchmarks real quick, on average the 4070 is about 35% faster than a 4060ti, and about 20% slower than the 4070ti. Looking at the performance headroom numbers in my 4070ti video it looks like you'd be able to run most of the games I tested with the 4070 at the settings I used in the 4070ti video. There were some games in that video where I was right on the edge however and even pushed a little further than I probably should have, so you'd need to turn some settings down a little bit with a 4070 in those titles from what I used with the 4070ti, but overall I think a 4070 would offer really nice VR performance.
Will a Rtx 4070 be better than a Rtx 3080 for VR in Sim Racing?
About equal but 4070 has 12gb of vram and dlss3😊
Im deciding between a 6700xt and a 3070. Thoughts?
Same here what did u go with?
When’s the quest 3 vid happening
Good question. It's probably going to be several weeks. I just got my Quest 3 yesterday, and I want to use it for at least a couple weeks to really get a feel for it, so I can highlight all it's strengths and weaknesses and give you guys a proper review.
@@Maraksot78 ok thanks
Hi, 8gb should be good for vr, the only issue are SteamVr and Oculus Dash, they use 2-4gb vram, is not the games.
How do i get that performance overlay?
It's in the steam VR settings, get your headset going then look on the desktop once the SteamVR environment is going.
No, it's pissing me off, (3060ti). The card is strong enough to give decent visuals for frames but if you turn it up a bit, it turns into a slideshow forcing a reboot. Yes if you don't crank it in some more stressful titles.
Man gpu companies should send you cards
That would certainly make it a lot less expensive to make videos like this one. 😂
Y does no man's sky run so bad on my 4060 ti 8gb
8 Rams? I can't vs 8 sheep
Virtual Rams**
Are AMD GPUs still not great for PCVR?
Not really if you wanna focus on VR nvidia is the way to go
It's pretty good now. AMD cards are just a bit less good at streaming. So if you want to stream VR to a Quest or pico with AMD it will take a bit more graphical power than with Intel or Nvidia.
They have good performance without bugs rn as far as I'm aware, but I've seen people say that NVIDIA just has a better encoder for compressed VR (Oculus Link, Virtual Desktop, etc).
Not if you have a Quest
And I don't know the exact performance difference, but don't think it'll be more than 5%. I got a 7900xtx and am limited not by the gpu but by my Pico 4 in visual fidelity. Even in Luke Ross VR mods for RDR2 and Far Cry 6.
Seeking a solution when something is not working properly is harder though with AMD, because probably more than 90% use Nvidia for pcvr.
lol i got 1 gig
AMD fanboys dont want to hear this no matter how much testing you do, and no matter how much evidence you present.
