Poor frametime when playing high end games

Framework Desktop
1

Hello!

I recently bought my Framework Desktop, and as a new Linux user, I am quite happy with my choice, but I have run into one particular issue when gaming that I do not know how to solve, and I wanted to know if anyone else had similar problems/knows how to address this.

I have been trying to play Helldivers 2, on a 3440x1440 resolution on settings that make my FPS acceptable to play (something on the range from 60 to 80, according to mangohub). It works great for the first thirty minutes or so, but, past that, the frametime gets absolutely destroyed (which I can infer due to the frametime histogram being all green peaks ).

It dont think this is due to thermal throttling, since the GPUs temperature seems to be around 65C, which I believe its a healthy range.

I am also using NixOs as my Linux distribution, could that also be affecting performance somehow?

Thank you!

Hi! My 2 cents:

Disclaimer: I don’t have a FW Desktop.

If the game runs well for some time and then frame times skyrocket, I would check for hotspot temperatures. Often the “CPU” or “GPU” general temp reading don’t tell the full story. Maybe something is soaking up with heat over time and then you get throttled. Also, try to run a long stress test/benchmark and try to see if the stuttering comes sooner with a warmed up machine (2nd-3rd run).
