Certain games such as the re4 remake and stray, will randomly drop to 5 fps for a few seconds, then jump back up to 30-40 fps. These games normally run fine at 40fps but I’m not sure what causes the drops.
I feel like that is shader compilation happening on the fly, it should dissapear after an hour or so (when it all compiles).
Shader compilation is often responsible for brief “hitches” but they shouldn’t last multiple seconds.
Oh, yea you’re right, it shouldn’t freeze your game
You might try cryoutilities and see if it helps. Sometimes drops like that are due to the system having to reallocate RAM/swap or other system resources, causing a drop. A lot of the cryoutilites addons are meant to reduce the frequency and severity of those drops, so it might help.
Otherwise your best bet is to enable logging of your performance data through mangohud, and whenever you have a fps drop check the logs/charts and see what happened.
Second for cryoutilities, it helped for horizon zero dawn on my deck.
How is that on Deck? I’ve only streamed it there via Moonlight, but didn’t play directly.
Zero dawn works perfectly. It even gets quite good graphics and fps. I loved playing it on deck. I actually much prefer it because of the gyro aiming with left trigger and the back buttons.
Hopefully forbidden west comes out for steam before I die of old age 😂
I’m also hoping for the VR one to be available on Steam, though I’m a little doubtful about that.
Maybe the long-standing SMT bug? Basically, when two threads on the same core are running, and one of the threads discards its cache, due to this bug, the cache is discarded for all the threads on the same core. This causes a temporary FPS dip.
A proper fix is due in SteamOS 3.5, but you can also turn off SMT by installing PowerTools Decky plugin to see if it helps.
Thanks for the info. Sorry for asking if it’s well known already. But if valve is going to fix it them I’ll just wait. Thanks for the reply.
If anyone hasn’t seen them, software engineer CryoByte33 delves into such performance issues and provides some utilities to help mitigate them:
I’ve seen ppl talk about that software before but I also saw ppl saying that causes more problems than it’s worth. I’ve been skeptical to try it out.
No harm in trying it out, none of the changes are permanent. I think it’s good, even just the swap increase is good as it alleviates memory pressure.
The heat may be a cause. I’ve experienced it a few time during long session. Just let the SD cool for 10 min on sleep mode and you’re good for 1-2h, depending of the game.
That is a good point. I should put on the osd that displays Temps and monitor them better.
It is not True. The Official Platform announces this FPS Drop severely is fake
What lol.
