i checked the system clock with the stopper on the phone, and it was correct.
then, i switched off programs like antivirus, and everything other possible, and it was still there.
so i managed, to format the whole HDD and install a brand new OS WinXP with integrated SP3.
after the install about a week ago, the game was running correct.
but yesterday it came back, and it seeks every 2min for few ms.
i tried system restore and set 2days before, and the seeking is still there.
so now i don't know what's happening.
btw it wont be the VGA, because when i play in normal mode (when you see the whole car) the FPS is about 15-30FPS on the BL GP track and the seeking is happening, and when i play after pressing the F button (when you can't see the graphics of the car, just the wheels and the pressures and etc.) there is +10FPS in average, but the same seeking is there.
so.......
