Thanks, mine says 'nvidia'. I found another Godot 4.0 linux build game and the same thing happened when I tried playing it, so it's probably something on my end.
I do know that vulkan generally seems higher end, but also I remembered that when you create a project you could choose either vulkan clustered/mobile as the renderer. I'm wondering if it would run without issue if the render was with mobile. Either way it's unfortunate :(
