I have a MSI 1080 ti that is about 2 1/2 years old and all of a sudden (past week) playing games have been sluggish. When I play COD:MW Warzone at max settings my fps is 45-60 which is way below average and when I change all settings to low it is oddly still playing 45-60 fps. This is also happening to other games, like Terraria where my framerate is 20 fps which shouldn't be happening with a 1080 ti. Now, what I'm suspecting is that the GPU isn't getting enough power (PSU is underperforming) but I want to know what everyone else thinks. Thank you for reading!
