it was all good until a few days ago i dont understand, im reinstalling it now hope that fixes it. i've already reinstalled my drivers and even different versions but that didn't seem to fix it.
Download RivaTuner if you don't have it already, and then lock the FPS in RivaTuner to your monitor refresh rate. This works when, for whatever reason, the game is struggling to manage frametime when your FPS isn't stable. Might not be the problem but worth a shot.
