So I've had my pc for a little over a year now, and suddenly every game has been having very low fps and is stuttering. I have a 3070 and a 7 3700x, so I think that my parts are decent enough to play almost any game without lag, at reasonable settings of course. The thing is that no matter what settings I choose in game, the cpu and gpu usage just get lower and lower, so my fps is almost always the same (which is very low). I can play a game at ultra settings at 1440p and get the same fps when I play it at 1080p and medium settings. I have almost never seen my gpu usage go over around 60% and it is always at like 50-55 ° C. For instance, I played a modpack in minecraft the other day and was getting around 70-100 fps, but my gpu and cpu usage were both under 20%. I just feel that it can perform much better, it just isn't.
