I quote my comment from yesterday. I can confirm that on WIN8 the game (BF4) works way better than on WIN7. It runs smooth, with high stable fps and no stuttering (settings on Ultra). With WIN7 I had fps drops and lots of stuttering (settings on Medium). Thanks for the people here who encouraged me to install windows 8. Now I can see that all the bad reviews it gets are inaccurate. It's a great windows in my opinion.
