I was playing Doom 2016 on my Framework 16 (with the Radeon RX 7700S) just fine when I was using (K)Ubuntu 23.10. However, when I upgraded to 24.04, it runs in Vulkan mode at 1 FPS. Oddly enough, OpenGL still goes over 120 FPS but once I switch over to Vulkan, it goes back down 1 frame per second. All other games are fine.
Can somebody else confirm this same problem? I am thinking about reporting this to the Mesa3D devs.
