Symptoms

I am on a Lenovo Legion 5 full AMD system from 2021 (5800H + 6600M) and experienced a lot of stuttering. While investigating this issue, I discovered something very strange with the benchmarks I can't make sense of.
The results show that the GPU is working good, producing lots of FPS, but the CPU is producing exactly 0 FPS.
I wonder if the stutter issue is caused by this non-FPS issue from the CPU, or if this is just a measurement glitch.

Reproduction

I just started the game and ran a benchmark.
The graphic settings doesn't seem to matter, I tried with a bunch of different presets and individual settings, the CPU never produces any FPS.
I also tried with some tips from the protondb website, which state that there is something weird going on with CPU clock timing, namely setting the kernel parameters "clocksource=tsc tsc=reliable" since someone mentioned he fixed stuttering on his machine this way.
