It’s a single player mode, what difference does someone upping sim rate in their game make to your experience in your career mode. I’ve only just started using sim rate change after flying two 3.5hr cargo flights back to back that both CTD when taxiing to parking at my destination, so wasted over 7hrs of my time. Now using simrate i can finish in around 40mins and if my sim crashes ive not wasted so much of my time.
