Earlier today I made the mistake of changing my graphics mid-game and ever since then it's been virtually unplayable. Previously, I had 60mhz 120mhz and 144mhz options but now the only choice is 144. I have verified files and uninstalled the game but I still only have 144mhz options. My monitor is freesync up to 144mhz but I never run it that high because the computer is getting a bit old. While in the game, it will stutter slightly, but at times the entire screen will freeze and everything snaps back a few seconds later.
