50% Loss in performance in games - AMD rx6800 RADV

Description:

Hi,

I have noticed a 50% decrease in FPS in a number of games under Steam

I have a rx6800 and a ryzen 5900x, in the following game I used to have up to few weeks ago (i haven't run games since last mesa update) locked 60 FPS, now I get about 30 FPS with 99% GPU utilization:

  • Baldur's Gate 3 (startup menu and in game)
  • Elden Ring (in game)
  • Shadow of War (in game)

mangohud shows GPU at 99% and high CPU utilization.

I attach BG3 screenshots with mangohud overlay

Please let me know if you need more info or additional data

Thanks

Additional info:

  • package version(s):
    • latest MESA (mesa 1:24.2.1-1)
    • latest RADV (vulkan-radeon 1:24.2.1-1)
