Vulkan Initialization Problems about conty HOT 3 CLOSED

The glxgears command works fine, so I assume the driver configuration is correct (using nouveau drivers).

Hi. The problem is that Nouveau does not support Vulkan currently, only the proprietary driver does. I understand that the proprietary driver does not work with musl, but that's the only way to use Vulkan on Nvidia for now (assuming your GPU supports Vulkan at all).

There is also a software implementation of Vulkan (called lavapipe or vulkan-swrast), which works with any videodriver and with any GPU, but it is very slow and has its own issues.

I would also suggest you to check ./conty.sh glxinfo -B to see if nouveau is actually used instead of llvmpipe (which is software implementation of OpenGL).

By the way, for Hollow Knight you can force it to use OpenGL renderer by adding -force-opengl to its launch options in Steam. And to make Proton to use OpenGL instead of Vulkan, run Steam with PROTON_USE_WINED3D=1:

PROTON_USE_WINED3D=1 ./conty.sh steam

Not all games will work this way though (for example, DX12-only games won't).

Both of the proposed solutions fixed my problems. I was able to launch both Hollow Knight and DS3 properly. However, upon testing my Steam controller in both games, I found that the button mappings were off. I don't think I'm going to pursue trying to get Steam running under Void any longer since it's not really a huge priority for me. I dual boot my computer anyways so I can play games on Windows if I so choose.

I ran ./conty.sh glxinfo -B as you suggested, and I am in fact using the nouveau driver. I hope this helps other people facing similar problems.
