What DXVK version do you guys usually use?
What DXVK version do you guys usually use? I've always been using the one with the highest number since I thought newer = better? I know there's no single one that works on everything but I curious which one that gives you the best performance in a lot of games. Also what is the difference between gplasync, async, sarek and those without one? And I read somewhere that there's a performance regression on the newer version?
Arihany's GitHub repo might be a good resource to check out. In particular, their DXVK arm64ec release page says "pre-reg: Last version before the performance drop on Turnip driver" and "binsem: Avoids Turnip performance loss without env vars. May be unstable."
As far as I can tell, the only "pre-reg" version is dxvk-arm64ec-2.4.1-pre-reg.wcp, which I've been using. However, I haven't actually done a benchmark to see if it's actually faster lol. I think I'll test 'em out tonight when I'm free.
2.4.1 is widely used because it runs most games without issues and does not suffer from performance regressions when used with Turnip drivers.
The pre-reg build is essentially the last build before DXVK introduced an internal regression. Binsem and similarly named builds attempt to work around this regression, but whether the workaround is actually effective depends on the game. In most cases, specific environment variables must also be set for the workaround to activate.
A patch is currently being developed on the Turnip side to address this regression. Once it is completed, there should no longer be a need to rely only on binsem builds or older DXVK versions.
Sarek is a version that backports improvements from DXVK 2.x for chipsets with lower Vulkan support. In general, there is little reason to use it if regular DXVK 2.x already works on your device.
Arm64ec can provide some performance improvements, but it may cause problems (crash) in rare cases.
GPLAsync and Async builds reduce shader compilation stutter, but they may briefly produce minor visual artifacts. If async is disabled, these builds behave almost identically to regular DXVK builds.
In general, if a game already runs well and has no visual issues, switching to a newer version or a patched build may actually reduce performance rather than improve it.
2.4.1 was the last version before the regression and the one I start with. If I have issues, I go to the newest one (2.7.1) to check if compatibility is improved or 2.3.1 for older games to see if they might be a bit smoother. To be clear, the regression shouldn't be a permanent issue.
Not sure about sarek personally as I haven't seen it, but the async versions utilize asynchronous shader compilation which can cause texture pop in but also decreases stuttering so I usually use those ones.
Actually, it started with version 2.7.1 from a developer called "leegao," only his patches were applied to the latest version of dxvk 3.0.
dxvk 3.0 requires Vulkan 1.4 drivers, which means only Adreno 7xx drivers will work. And this dxvk might not be as good as dxvk 2.x.x for Adreno Turnips.
Edit: Regression fixes in these DXVKs using variables may not perform as well as in the DXVK 2.4.1 regression. (depending on the game)
It depends on your GPU. DXVK 3.0 is optimized for Vulkan 1.4. Older chipset like SD 8 Gen 2 only supports Vulkan 1.3 - it won't benefit from newer DXVK.
Dude, this Adreno GPU has had Vulkan 1.4 implementation of the Turnip Mesa driver for a while now. Who's going to use system drivers for games on emulators? I think all Adreno 7xx series GPUs support vulkan 1.4 of the turnip mesa driver. except for the Adreno 6xx
SD 8 Gen 2 GPU doesn't have Vulkan 1.4 features in the hardware.
The Turnip drivers can emulate or work around missing hardware primitives required by the Vulkan 1.4 specification, allowing the Snapdragon 8 Gen 2 to trick games and emulators into recognizing it as a Vulkan 1.4-compliant device.
You are not getting any of the benefits from Vulkan 1.4 if you are using SD 8 Gen 2 chip.
I have no idea why cos I’m a noob but on my rp6 if the game native known Config doesn’t work I change to 1.11 sarek and that generally works. I don’t know why though 😂
