I'll try it later and see if it fixes, thank you.
Also, thanks @noodlejetski@lemm.ee as well for this tip.
Sounds like a memory leak. Have you checked your RAM and GPU memory when this happens? You can use btop and nvtop. If it's a memory leak, it shouldn't happen with every game though.
Just got the bug to appear again. Plasma monitor shows 8.1/15.4GB of ram being used, but nvtop shows 100% GPU memory being used.
If the LD_PRELOAD="" command doesn't work, I'll see what I can do about the vram usage.
Try lowering some VRAM-heavy graphics settings. This was happening with Elite Dangerous to me with Proton 6. It was fixed with later Proton releases but until then I played with lowered VRAM-heavy settings.
Try disabling the steam overlay I had this issue with doom eternal. Assuming it's on steam and since I believe this is ac syndicate disable there overlay aswell has this problem with division 2
yup, and if that doesn't fix the problem, try adding LD_PRELOAD="" to the game's launch parameters

This, and specifically, you can also try disabling steam in game recording for whatever game is giving you trouble. I have found it to nuke performance in some games similar to what you are describing.
By disabling the ac syndicate overlay you mean the ubisoft one?
Yes that one in the launcher settings and as noodlejetski said that command should do the same thing I think
Are you monitoring component temperatures?
No. That's a good idea, I'll start doing it.
Yeah the fact that it takes a while to start happening leads me to believe you may be thermal throttling somewhere.
Hmm what is steam loading by default that clearing it would solve it?
afaik its for the new screen recording feature
I have this same issue in my system. Haven’t been able to figure out.
This is independent of setting. I play cyberpunk at all lowest settings + fsr performance on a 4080 and i still get this issue after an hour.
Why are you using low settings on an RTX 4080? On a 4090 I can max out every setting and the game runs like a dream. Is the 4090 really that much more powerful or do you have a logical reason to turn down the settings so much?
Just for testing purposes. To show that the stutter isn’t because of my hardware not being able to run the game at the current settings.
Like OP said, after an ~hour of gameplay, every game starts to stutter for me. Ive had this issue on Divinity Original Sin2, Marvel Rivals, Space Marine2, Cyberpunk, Elden Ring and probably other games i can’t remember. It’s probably a nvidia driver issue or some nvidia config issue.
Edit1: I don’t think it’s a memory leak issue since (correct me if im wrong) those are usually related to issues with the game engine, but we’re seeing this issue across multiple games with different engines. One more thing to note is that im using the flatpak version of Steam. I’ve been considering switching to the regular version of Steam to see if this solves the issue.
Well that does in fact sound like a memory leak issue to me.
Did you try another distro? How do your games run in Windows?
I thought memory leaks are related to game engine issues.
The games run without any issues ok windows. Ive only tried manjaroOS. I dont want to try other distros because I’ve already set everything up on my desktop. It would suck to log in to everything again.
@abobla do you have nvidia or amd gpu?
nvidia gpu, my fastfetch info is posted in the post's body: GPU 1: NVIDIA GeForce RTX 3050 Mobile [Discrete]
Also, did you try the LD_PRELOAD="" %COMMAND% mentioned in the post? This solved the issue for me.
Have you tried changing whatever compatibility layer you're using? Sometimes, I have some visual glitches and changing from, for example, GE-proton to proton experimental fixes it. Install an app called "protonplus" and find more compatibility layers from different folks.
I think heat
Alternatively, since it looks like you're running on battery, does something in your setup change to a "low power" performance mode that throttles your system?
since it looks like you’re running on battery
Sorry for that, I ran fastfetch when I wasn't playing, but I always play using the charger. My laptop decreases it's performance when on battery, but it doesn't wait for low battery to decrease, it's instantaneous.
Is it only when you use the mouse or keyboard? Used to have something similar a few years ago on my Steam Deck with some games. Never figured out what it was and I think it doesn't happen anymore.
Consider disabling gamemoderun if you're using it.
