i dont think so...because i have good FPS (70) but is like time of the game is faster thant the real time, is possible that the clock setting of lfs was not good?

hello i am sorry for my english but i will try to be the most clear as possible...

So since today when i play on lfs offline the game run most rapidely than normal, the time pass most speed, for exemple to go from 1:10.45 to 1:32.45 it will not take realy 22s but only 18... so the game is not controllable, and the most big probleme is when i play online, the game stop everytime for equalising my game time (who go faster than the normal time) with the normal server time...
Please help me for this big bug.....
THANK YOU
