I have a Mac Pro workstation with an NVIDIA GPU installed, running CachyOS, and I casually play video games on it. I have Cachy-Update enabled and perform rolling updates on a daily basis. In the past 1–2 days, I’ve noticed that games start dropping frames in a certain pattern after a few minutes of gameplay. I originally thought it might be related to proton-cachyos-20260420, so I downgraded to proton-cachyos-20260409, but the issue still persists. I used to have stable fps between 120-150. I used Black Myth: Wukong as an example, but the issue also occurs in other games like Cyberpunk. The issue is also reproducible using Wukong’s built-in benchmark.
