Not great. Sometimes there is a lag spike, and this happens every 10-30 seconds, and sometimes you end up crashing. Best idea is to have an Ultra Low setting. Also, one time, I was recording a trailerless trip from Airolo to Nuremberg and at around 32 minutes in, a lag spike caused the recording to end. Uninstalled. Don't play this garbage, go play ETS2/ATS. It costs more and is not on mobile, but in the long run, it is more worth it than this garbage.
