Recently I purchased Battlefield 3 on origin running Windows 8.1. On windows 8.1 I was getting around 90 FPS Max settings. I decided to downgrade to windows 7 and download battlefield on that OS, when I ran the game and joined a server I was getting a max framerate of 3 FPS whether I was on max settings or on low settings. I have tried uninstalling the game and re-installing it and that didn't work, got the latest drivers and that didn't fix the issue so i'm am at a point of I have no clue what it could be. Does anyone know what it could be?
