what causes certain games to severely drop fps for a few seconds?

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.

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.
