He guys, here my PC - intel i7 2600k 16 GB - win7 64 bit on SSD 250 mb - nVidia GTX760 3 GB Latest nvidia driver installed. Talking about SINGLE player (no online server). If i press CTRL+F rF2 show me from 160 to 220 FPS (about) but the problem is that the driving IS NOT fluid. Some time is like to FPS go to 10 for some decimal of second and after it go fluid and linear. I start to be crazy about this. I tried to remove all and reinstall e fresh lite rf2 (300 mb) with only a track (Silverstone) and a car (Corvette) but nothing changed ! The other issue is this one. If i start in 64 bit mode rf2 do not detect my intel i7, like here: http://i.imgur.com/nuKBPK4.jpg But if i force 32bit .exe (use 32 bit executable in 64 bit system) rf2 detect correct my intel. http://i.imgur.com/JkKJLL6.jpg In both (32 and 64) i have that lag problems. I've tried a lot of quality combinations, but if a put all to low i can do 300-400 fps but lag problem remain . Thank u for helping me.
