im guessing you still have all the clutch assists on? the clutch system in beam is probably one of the best there is.
gameplay settings, and might as well disable all the other assists while youre at it, if you have the H shifter, and use the realistic gearbox mode
I know even driving schools who use BeamNG.drive for training learner drivers the raw feeling of a clutch to prevent damages on they're real cars. It is really the best game i know in terms of clutch system.
i used it to learn what bucking is and grabbing points. still wore down my irl clutch quite a bit but it helped me realize how to correct it quicker since i knew what a certain problem looked like.
