For the past couple of months I have been experiencing an issue in multiple different games (CS:GO, Warzone, Forza 4) where I am on a loading screen, the frames will tank to about 0-1 FPS. For instance, I can't even get past the training in Warzone because the game runs at not even 1 FPS I can't interact with anything, and so have to alt+f4. However, when I alt+tab, the preview of the game looks to be running smoothly, but as soon as I tab in, it becomes almost unresponsive. I have no idea what this is, and even what part of my PC is causing this issue! I have a MSI Geforce RTX 2080, 16gb of RAM, Ryzen 7 3700x
