90% performance drop driver 520.56.06

I am using nixos. Two video cards amd w600 (radeon open driver) and P106-100.

When switching the driver from 470 to 515-520, there is a drop in performance.

Environment variables remain the same, only the driver actually changes.

The situation is the same on both X and Wayland.

nvidia-smi shows that the process is running on the video card. At the same time, I get 15 fps in dota2, together 120-150 fps
