Hi ! I play BF3 since 2011. Since then, i upgraded for a GTX 1070 (MSI ARMOR 8G). I had never have any problems. I play regulary. But last time i tried to play, i had horrible framrate (30-50 FPS). And i easily identified the issue. The game isn't using more than 30 % my GPU, sometimes like 20 %. I can play any others games, it's only with BF3. I already used DDU and reinstalled last drivers. I have the latest version of Windows (May update), latest Nvidia. I used to have 120 FPS on this game. I already reinstalled the game too.
