As the title says my FPS has suddenly dropped significantly on all maps and certain maps display significant artifacting. This only happens on BF3 -- all other games are fine, both those more and less demanding, e.g. Crysis 3. 7970/7950 Crossfire, 13.8 beta 1 drivers (installed almost two weeks ago, problem only just showed up yesterday and worsened today). 3770k. 16GB RAM. As I said, all other games are fine. The FPS has gone from 60-144 to 25-55. Temperatures are fine. GPU usage on both cards is lower than normal. 95% sure there isn't an external program causing issue. I've tried repairing through Origin but it said it was fine and I'd really rather not have to download 30GB+ again on my dismal download bandwidth. Any fixes anyone?
