I have been playing Skyrim for a while and it has worked really well. I have played on ultra high graphics without any problems up intil a while ago. Suddenly the highest graphics perform like the worst. The grass pops up just a few meters in front of me and details on object appears like 10 meters in front of me. I have tried to reinstall the game twice but the problem is still there. I can walk down a road and out of nowhere a tower appear. It is getting kind of annoying.
