That was my first thought... it happens even if i go to the boxes and back in game... it just barely moves... And the clutch is all okay but if i keep accelerating on max it eventually ends up burning the clutch

Hello guys! My problem with my driving wheel is that i assigned every button, axix and stuff, everything is working but when i accelerate the car barely moves... if i go up a gear it makes no difference... rpm goes high but car still barely moves... any tips?
