    Tons of indie games with retro aesthetics don't seem to care for optimisation even if it's a simple shooter.
    Worse yet sometimes they'll force Unreal Engine's Lumen to achieve basically raster graphics we've had for decades.
    I guess it's their vision and all, but it seems dissonant with the graphics of the game how you need newer cards to run the thing.

      I'd love it if the loading message was randomized. Some others like "preparing level" or "building platforms" would be fun, but you could have a couple rarer ones like "beating the level for you" where you can both see and hear it, maybe through a low volume and by making the black background partially transparent. That way you can just make out the shapes and sounds of the level in hyper speed before being dropped in it.

      @@sulfur2964 OpenGL is functionally a dead end. Development has ceased entirely on it, and it will not see any improvements nor new features. As far as I can tell by the presentation (that also uses AI generated images, which as far as I am concerned is already a red mark against something, I also have no interest in watching a nearly 2 hour video that's functionally just someone going over a slideshow, so maybe something was covered there but not in the slideshow), with all the main arguments essentially boiling down to pointing at numbers entirely out of context, and pretending like a point has been made. (ex, Vulkan games in 2023 vs GlideFX games in 1999, which ignores that game development as a whole has changed since 1999)
      Also minimum system requirements for an API doesn't exactly mean anything - sure you can now "support" games on something as old as a geforce 420, but no one is going to be practically targeting hardware that old, meaning it's equally as valid to say "The GeForce GT 630 is the minimum support for Vulkan".
      Also OpenGL driver support is known to be sketchy at best. This has been well documented.
      Also the wording of "API drivers buggy" isn't a search term normal people will use. instead, "API driver issue" is FAR more likely to be searched, which shows 15.6m results for DirectX, 10.8m results for OpenGL, and 3.4m for Vulkan. (also the original search query gives completely different numbers, with exclusively DirectX being the only one even remotely close).
      As with any sudden and significant performance boost, I would sooner suspect a poorly implemented Vulkan pipeline over any actual benefit to switching to OpenGL.

    Unreal Engine game dev here - in principle you can select your renderer in the project settings - DX11/DX12/Vulkan. The engine uses a renderer abstraction layer, allowing the engine to call render commands without worrying about the implementation, and the Render Hardware Interface (RHI) layer converts it into commands in the chosen rendering api. That said, it’s often it’s easier to pick one and stick with it, as some material functions aren’t universally supported so increases the QA time significantly!

    Having the game do a pre-recorded run for shader compilation is a really clever idea, even if a broader solution is coming for the next versions.
    For the AI/pathfinding optimization I had a similar issue, and what I found is to have a singleton responsible for all enemies, and have enemies queue into it to have their next update calculated (can be for path update, sensor check, whatever could cause an issue in large numbers). That way you can control how many calculations you want to per tick (could even adjust it dynamically based on performance), and guaranteed to not have any accidental overlaps.

    Hey so with your Pathfinding optimization, it might be helpful to add your Knight agents to a queue and have a manager cycle the queue, invoking their pathfind() function on whatever interval you’d like.

  • @MasterTeeee
    @MasterTeeee 3 місяці тому +7

    Baked lighting will also make your finished product larger, in terms of memory. Same with OC.
    All these techniques have the side effect that you're effectively switching the cost from processing cycles to memory usage.
    One thing to bear in mind with this (amongst many) is that, processing cycles are effectively infinite, you'll always have more, you'll just drop render frames if there aren't enough available. Memory is finite, and if you run out, the kernel will either crash (panic), or kill your game, causing it to crash.
    Now, in a game of this scope, it's probably not a huge deal, but if the engine has memory leaks (and all engines/code has memory leaks somewhere) and/or your game code has memory leaks, or somewhere along the compilation chain there are memory leaks (you see where I'm going), then after some time, you'll start to encounter issues that are incredibly difficult to fix.
    I just wanted to clarify that what seems like magic, and to always be a good idea, does have some tradeoffs, and is something every engineer should be aware of.
    PS: Also, NEVER delete files/directories that you don't know what it does. Just rename the directory (add an _ to the start of it's name or something), or change the file extension (.old works well) and this will usually (there are exceptions) have the same effect as deleting it. Then, if you hit a castrophic, "I shouldn't have done that" moment, then you can just rename it back, even if you have boot Linux from usb or something.

    Another optimization: The thing with computing the shortest path from multiple sources to one destination is that it can be reversed. Instead of doing a calculation for each source, do only one calculation from the destination to all sources and you will find the same paths (but reversed). This ensures that you do minimal work and don’t double calculate anything.

But reducing it down to 1080p I got ~145-155 fps, which is perfect for my 165 hz monitor. I didn't feel any difference - something I couldn't say for modern titles, where 1080p starts feeling a bit fuzzy.

    Added to wishlist. While I'm sure the pathfinding randomization technique will generally give you a decent result, you could still end up with situations where most of the random numbers end up at the same time. A more bulletproof solution would be a simple queue you add enemies to. Every 20 frames the queue would advance and call the enemy's pathfinding routine. Additionally, you could have the pathfinding routine take a callback from the queue so that you could guarantee the last calculation was finished before performing the next.
    Maybe a bit overkill, but hey, this is a video about optimization.

    Shader pre-compilation is an essential feature for every modern PC game. Glad to see it being implemented, even if it's done in a "unusual way" :D
    For your game, consider adding a integer scaling for resolution scaling, while also giving an option to disable the filtering. So players can play at 1/2 Res, 1/3 Res, 1/4 Res, etc... Prodeus added this option and I personally love it, even though my computer can easily handle the 1440p Native res, I prefer to play older games at 1/3 Resolution to get the those chunky pixels.

    A better pattern for the pathing stuff, FYI, is to use a round-robin scheduler. So you set a budget for how many agents are allowed to update on a given frame, and each frame you have a manager move the index by n slots and update that many agents. So you can guarantee a fixed load per frame and also guarantee that an agent only goes so many frames between updates. You can use this pattern for a lot of things to smooth out your load to be precisely consistent over time.

      Actually turning off animations isnt big optimization benefit, sure every little is good but to turn off as much dynamic lighting as possible was here probably one of the biggest Performance things.
      Also why the heck did he had dynamic lighting if basicly nothing could interact with it, such things are the reason for bad Performance.
      Also to make the pathfinding calculations dont happen on the same time only reduce short lag Spikes/time freezes. To make the calculations every 20 frames is a good thing.
      To the topic of culling, yes it is good but not really important because computers dont have anymore the Problem with drawing normal polygons. Here it is a thing of good models, if your objects are good, you dont use transparent textures and if you have the same object multiple times it uses only one draw call(a Signal that tells the graphic card to draw a object).
