ok guys i have big problem with wheel i have wheel "Genius Speed Wheel 5 pro" with vibration Feedback and i have problem with vibrations. wheel works fine when feedback is off and all game are smooth but when i turn on feedback in game then my picture begin to lagging or i see that game is not smooth anymore and i don't know what to do. i have good configuration and rest games are smooth too without any lag. my computer is AMD Athlon64 x2 with 4GB DDR2 RAM and graphic card ATI Radeon HD6670 with 1GB DDR5 128-bit. i think this configuration is more then good for race 07.
