My car is faster than my mate's car

we were doing drag races on the highway on 2 different servers and on the exact same settings and cars (automatic cars) and my car was just signicantly faster than his. How can we solve this issue?

It’s possible his game is running below 60 fps so his physics are calculated slower, making him go slower than you.

ok thanks for your answer

I tried to limit my fps to 30 to have the same delay but it didnt work. Do you think that there is another explanation?
