Hi all. I have a problem and want to ask if someone can help me. I have two EVGA GTX 680 SC in SLI and when I was made the test´s in heaven I could get 95 FPS, but one of them broke. Now I have another one and having placed in the same place where it was broke. I uninstalled the drivers with Unistal factory and then went into safe mode with driver sweeper swept for proper uninstall. New tests made in heaven, I saw that I lost half of the performance, I can only get 56 FPS. In Battlefield 3 could normally have between 120 and 160 fps and can now only be 30 to 60 fps. Had installed the 306.23 driver, since I stuck my previous driver 306.02 and still the same. If they need to know my specs are in my project Obsidian - ROG Rig Mod. Someone can help me? Best Regards.
