[SOLVED] Bad perfomance after 15 minutes of playing

Check your PC thoroughly for dust before complaining about low FPS.

Hi. It's my first message on forum, so i sorry if can be stupid. I have a problem, that after 10-15 minutes my fps droped from, in example, from 150 to 30-40 and from 60 to 10-15. i just tried everything, that was written on forum, but i really dont know what to do. This problems i have like a month, before everything was ok (i dont think that its because of update, because i can setting something in system incorecct). I use Wayland as main system, but in X11 problem the same. Thank u!

Why are you running a kernel from last december?
How can you be using hte 580xx drivers along that when not using dkms??

Then there obviously must be no problem.

Same goes for

What's "my fps"? glxgears?

most reasonable: as this is a laptop - and a few years old - it's likely it's inside is full of dust - and it just heatsoaks and thermal throttles
best idea: open and clean - and maybe replace thermal paste on both cpu and gpu

That's out of the question. I do this every few months. The computer doesn't even have time to heat up under load before problems start.

I sincerely apologise, I messed up in section 6.16.2-arch1-1.

As for dkms, I don't know, to be honest. But it shouldn't work for me without dkms or what?

journalctl -b -p 3: no errors (just warning about ACPI):

That's all i have there when session started:
kernel: ACPI Error: AE_ALREADY_EXISTS, During name lookup/catalog (20250404/psobject-220)
kernel: ACPI BIOS Error (bug): Failure creating named object [\_SB.PCI0.XHC.RHUB.SS02._PLD], AE_ALREADY_EXISTS (20250404/dswload2-326)

I used mangohud for this in War Thunder and Ready or Not. FPS in game... like commonly fps i think.

I looked at the articles you sent and tried them, but they didn't help.

well - if it's not thermals could be some memory leak eating up reasources
use another device like your phone to ssh and keep an eye on htop if and what maybe hogs memory - same using nvtop for vram

What did you do *exactly*?

Test one of those: same effect?

Zangy · 2025-08-25 20:08:23

I took apart the cooling system as you suggested — there was a layer of dust between the processor and the copper that wasn't visible from the outside. That turned out to be the cause of the throttling, even though the case itself stayed relatively cool, which is why I initially ruled out overheating. After cleaning, everything is working fine now. thanks for pointing me in the right direction — I’ll make sure to check this first next time before posting on forum.

The case cannot heat up if the heat cannot escape the CPU.
But how's there anything between the die and the cooler that's not some heat conduit - is there no thermal paste or heatpad?

The first thing I thought!
when in doubt, clean it the f out
Cryp was spot on.
use a laptop cooler stand or something, never use lappy on anything that has hair or lint (fuzzy fabrics)

cryptearth · 2025-08-27 14:01:57

nah, was just a lucky guess - and it could had been wrong the same as it turned out to be the correct idea
laptops are rather strange over the years
a friend of mine, really big movie fan, has about 5.000 optical media and pretry much daily converts and rips and what not
his last system somewhat "degraded" over time - in terms of even a clean fresh install was noticable slower than when I first touched it - and he is a rather clean person and has a cooler and such - the system was just done - and he already had opened it twice and cleaned and repasted

my point is: even if you follow best practices and keep your mobile device clean both hardware and software over time (several years) there's quite some degradation far more noticeable than equivalent desktop components

another example: I have an old amd-fx system (fx-8350, 32gb ram, am3+ platform with pci-e 2.0) - and although it was quite powerfull about 10 years ago - starting it up today and just install an os on it feels like an entire day wasted and only accomplished from cold boot to merely graphical desktop - aside from that it's very inefficient and powerhungry and wasting heat compared to my current setup
there's a point when old hardware is just old and should be treated as such

I'll re-iterate (though this might be a purely linguistic problem; bad description)

Literally having dust or air or any kind of gap "between the processor and the copper" is a much bigger problem that could not be fixed by dusting things off.
