I'm confused why my computer lags incredibly after i open programs such as my gamecube emulator and my league of legends client. It only seems to lag when i open gaming related programs. After a few seconds its returns to normal until i click out and click back in again, then it lags again. Also this only happens sometimes but more often than not, and im lost for a reason why. I'm using Windows 10 Pro. I'm not sure what else I should specify.
