I have a RTX 3080 GPU and an i7-10700k CPU, and my computer can't reach 240 fps on any game. Valorant is 170 fps, Halo is 120, and Overwatch is 200. I'm unsure if games are incorrectly using my integrated GPU still, even after changing my settings so that wouldn't happen anymore. My gpu utilization doesn't seem to be high and my cpu never goes over 70 degrees celsius, which makes me think it isn't pushing that hard either. I'm unsure why the performance has fallen down so far compared to what it was. Also, I make sure to never have anything open in the background.
