having some slowdowns

[tlawrey20]

this happens with pretty much every game i play with dolphin. they all run perfectly for the first time i boot them up. barely any stutters audio is good. and a solid 60FPS. then after a day or so of playing. i save, quit, then open it up again the next day. and now i have all sorts of problems. the games are stil;l very playable. but i get stutters every 30 seconds or so. (the audio is still good though) and some parts slow down to a crawl when hey didn't use to. (for example. ive been playing metroid prime trilogy, and the water never slowed anything down. now when i just into water the game slows down to like 10 FPS) and before any of you say that my computer is over heating. i promise you its not.

(GTX 1080, I7 8700K, and liquid cooled)

i knew it wasnt over heating but i did run a temp test just to be sure. and nothing got above 60 degrees. this seems to happen after i save multiple times. but that might just be a coincidence.

i just want to run these games and have fun. but the stutters are so unbelievably annoying during gameplay i just dont want to play anymore

I wonder if one of the issues is just the sheer amount of shaders that are compiled for something like Metroid Prime 3. As you play a game, Dolphin accumulates shaders, and has to recompile those shaders if they're for some reason not present when you reboot the game. While they're recompiling, your computer will be a bit slower because that will take up as many cores as it can in order to get done fast.

In a game like Metroid Prime 3, where you can have GBs of shaders... I'm wondering if maybe it's just never finishing compiling old shaders and you're running into that. There also will be somewhat rare lags when the JIT cache has to be refreshed, but those should just be a tiny hitch at doors. You can try different shader compilation modes, lowering your internal resolution (for the water issue, that's EFB copies close to screen which can easily bring bandwidth to a standstill due to GPU <-> CPU communication being slower on modern computers than the Wii.)

right now im only playing metroid prime 1. but this happens with pretty much very game i play on dolphin

I had a similar problem.
Using Display Driver Uninstaller to uninstall the NVIDIA Drivers and GeForce Experience, and manually install only the Drivers but NOT GeForce Experience solved my slowdown / stuttering problems.
[EDIT]
Also can i now use the Vulkan Backend without problems, what i couldn't before.
