Nvidia mouse polling (aussie.zone)

submitted 2 weeks ago by [email protected] to c/[email protected]

9 comments fedilink hide all child comments

Hi there, I have a quick question regarding my system and mouse lag with nvidia proprietary drivers on X11 using OBS with NVENC.

My system runs great with red dead redemption 2 for around 40 minutes until I begin to lose frames when mouse looking. I can leave the mouse and perform intensive graphical actions and it still runs perfectly without mouse input.

I assume it might be a misconfiguration on the mouse or a known bug with nvidia but am unsure of exactly where to begin looking and/or what terminology I should use to Web search the problem.

Could anyone please point me in the right direction?

If it's time-based, then you have a memory issue. You're probably getting the slowdown from the kernel OOMKilling things as fast as possible to keep the system alive.

Would that affect only the mouse because otherwise I still get amazing performance when I don't use the mouse?

It would make the mouse polling slowdown noticable, but there are other background things happening if you're having what I think you're having. Just because your game is running doesn't mean the rest of the system isn't suffering.

Install MangoHUD and watch your resources while you're playing and running OBS at the same time. Both take up a lot of memory.

I neglected to configure mangohud to show temperatures and it turns out I was getting 90°c CPU!

I had a sus clip on the CPU heat sink and missed a system fan plug on last rebuild.

Everything should be good but I'll need to finish it up tomorrow morning after I purchase thermal paste to be sure.
