when I try to play Fifa 2005 the game runs too fast even when the settings (of both the video card and inside the game) are set for best quality and lowered performance, and the speed inside the game is set at low. The players move so fast that is impossible to play. I tried reinstalling the game but nothing changed.

Seems to be a fairly common problem with the game.

I've been searching the web for this problem and it seems that the main problem is the CPU-speed. FIFA detects a lower speed then you're working with. To test this you can run the EZ-utility in the support directory of fifa. But now I'm looking for an command/program so that fifa detects the right speed.

I have the same problem. The problem is indeed the cpu speed detection used in fifa. Its mainly laptop users such as me that have this problem because of the built-in cool n quiet feature some laptops have.
