Hey. I’ve noticed a significant performance drop in video games (namely Spelunky 2 under Proton) after updating from kernel 5.9.8 to 5.9.9. I tried to reproduce this with some random free benchmarks:
Basemark (vulkan) score goes from 2954 to 2460
Tyler’s Frame Machine (vulkan) score goes from 4977 to 4276
Using OpenGL I get similar behavior.
I’m using a AMD Ryzen Pro 3300U with Vega 6 graphics on Fedora 33.
Did anyone notice anything similar? What sort of logs would be relevant for this?
