Weirdly specific FPS drops in borderless windowed mode.

[KageTokage]

Okay, nevermind.

I just logged in today after more troubleshooting (I've been having issues with my display freezing or turning off abruptly), and now I'm getting a smooth 60 FPS even in the places I mentioned were lagging me out earlier. The GPU load is also about 30% lower then it normally is.

There's clearly something weird going on here, but whether it's hardware or software related is beyond me.

It seems like the GPU just doesn't work properly when I boot up the PC sometimes, which results in poor FPS and instability that potentially causes it to shut off regardless of how high/low the temperatures are.

EDIT: I think figured out the issue. The motherboard is sometimes misdetecting my GPU as an PCIE x1 card instead of a x16, which naturally would cause performance issues and likely also explains the random shutdowns as it's probably not allocating enough resources to the GPU for it to function properly. Just gonna have to keep checking the detected setting with GPU-Z before I start playing so I don't run into unexpected crashes, at least until I can resolve the issue and/or get a new GPU/motherboard.
