My first truck I drove with bad brakes for close to two years. The rear drums were worn so bad the insides were egg-shaped. Braking after coming off the interstate made the whole vehicle shudder. Finally got those fixed and it smoothed the ride out quite a bit.
So I know ahead of time, is it a requirement to fly with the realism settings maxed? For the moment I fly without engine overheating/mixtures/etc.
