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.
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.
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.
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.
It is not True. The Official Platform announces this FPS Drop severely is fake
What lol.
