Hello people , i just joined recently. I am experiencing problems with fps , i tried everything , from inside game vsync to outside nvidia specific max fps and sync. Sometimes it stays stable for some time then it starts shuttering again and GPU going crazy 100% ,lagging the whole computer.Tried to limit it also with RTSS,same thing.I dont really understand. I have 5600x unlocked/3070ti/16gb ram , m2 samsung. I tried lowering it from 1440p to 1080p , it was kinda better but not good. I think it doesnt have anything to do with that. Something else hits hard , i dont know what. Any thoughts?
