I updated my GPU drivers earlier and found that it totally wrecked the frame rate. before installing, I was getting 60fps average with a lowest recording of 58 with most things set to ultra. after updating to 12.8, it has more than halved to an average of 26, with a lowest of 19 with no settings being changed. the game was totally awful to play so I fully installed and went back to the previous version I had installed, but found out that it didn't fix it. I even tried doing a system restore to a few days ago, but this didn't help either. any ideas why this is happening? I'd understand it if it was just the latest drivers, but a clean uninstall/reinstall and a system restore didn't correct it.
