Hello, recently my rtx 2080 ti had to be replaced and in the meantime I borrowed my friends gtx 750. He has a gtx 780 in his rig. When we went ahead and played minecraft the results were shocking. I was getting 500+ fps in 1080p and he was getting max 100fps with fps drops to 15fps. His game was stuttering very badly while mine never dipped below 400fps. Also note that I have an (i5 10600 non k) and he has an (i7 4770k). His gpu usage is constantly below 30% usage while mine is 100% all the time. We uninstalled the drivers, applied unlimited fps in nvidia control panel and minecraft, disabled vsync/gsync, applied max performance power profile in windows, overclocken slightly in afterburner to no awail. What can be the cause of this? We have tried everything that came to mind.
