Playing with Mesa OpenGL drivers on Windows

[shirok1]

Not an actual issue, just something interesting to play with. I see that Mesa is providing GLonD3D12 and Zink (GL on Vulkan). I downloaded Mesa OpenGL drivers from https://github.com/pal1000/mesa-dist-win/releases/tag/24.1.1 (notice that 24.0.9 should be used since they broke it in 24.1), extracted these files:

• opengl32.dll
• libgallium_wgl.dll
• libglapi.dll
• dxil.dll (for GLonD3D12 only)

Beside diva.exe. Then launch the game as usual. A wrapper device should be showing in GPU Info:

To switch between drivers (backends), use GALLIUM_DRIVER environment variable. Possible values: d3d12, zink, llvmpipe (CPU backend)

Unfortunately, performance statistic OSD is not quite working on my machine, so I won't be able to prove if this worth a try when GPU vendor provided a poor GL driver (not my case, I'm running an NVIDIA Ampere). But solely from frame rate perspective, I can see that Zink only loss about 2 to 3 frames and GLonD3D12 is even on a pair with stock driver. Would you like to test it out?

Hi i tested what you wrote. with just extracting the named dll the game instant crashes. by extracting everythign the game boots but idk where to change the variables. i use a amd igpu and find a way to get videos working on it and would also test if this gives better performance since amd has a pretty bad opengl support

Maybe you can provide some log? Run the laucher in terminal (and maybe with the parameter that make the game itself launch immediately). Even the launcher window will provide some useful information, copy the text or screenshot.

Plus are you using the cutting edge PD Loader build? https://github.com/PDModdingCommunity/PD-Loader/wiki/Latest-test-build P.S. @korenkonder it would be better to leave a link to the test build and give out some common bug for the stable releases

[korenkonder]

give out some common bug for the stable releases

What do you mean by that?

Glitches like #2. I personally also only get DivaGL working after switch to test builds of PDL (but I don't remember the detail of tweaking so I'm not 100% sure whether test builds are actually necessary).

(And by "leave a link" I mean in readme)
