When I move my mouse in minecraft windows 10 with rtx. It went from 90+ fps down to 0-10 fps instant! the gpu usage also decrease from 90-100% down to 5-40% depending on how fast and much I move my mouse… I have tested to reinstall the game and change the hz on the mouse but I still have the problem!
Everything worked fine but then I turned off my pc and the next day I tested it again and I had the problem for no reason. I haven't change any setting or something it's so weird.
