GPU high frame time, choppy screen

[BK_]

Hey so my screen is choppy, im 100% certain its not a monitor issue, i tested 3 monitors on the same pc and all of them had the same problem and all of them different refresh rate testing, on a different pc which is worse this issue didnt happen. So basically it looks like the frames are choppy and on the online ufo test the ufo is like glitching back and forth and so does the background. It happens on every refresh rate, every speed of the ufo test, yes my bios is updated and yes i tried freesync and vsync. My nvidia drivers are the new ones. I tried older ones, i tried ddu, i tried unplugging gpu and plugging back in, i tried different gpu ports, i reinstalled windows and i downloaded a program and saw my gpu frame time is jumping between 6 and 200ms Specs: R5 7600, RTX 4070

 

I just tried my old pc it was completely fine and that pc is so much worse aswell. The nvidia driver update was the same on both pcs. This issue happens in games aswell but gets fixed a bit when i have other games in the background for some reason, and also gets fixed when i limit the fps in that game to 360, if i the fps on even 280 it lags like crazy. Even on a 144hz monitor 240fps is laggy and 360 is ok. Thank you everyone for helping. I already made a redit post on this but i added a few details here, thanks everyone for the help.

Btw this issue started happening a few days ago.

 

ON THE VIDEO, LOOK AT THE TOP ROW IN THE BACKGROUND OR THE UFO, YOU WILL SEE SLIGHT LAGS (THE SCREEN IS NOT SMOOTH AT ALL)

 

Thank you everyone for the help, i really appreciate it.
