Which one? Like the majority of teams (other than Haas and possibly Alpha Tauri), they have multiple simulators). Was it the rail based one?I drove the McLaren simulator and felt very unwell afterwards!
I struggle in driver in the loop simulators, even when they are very good, but it is possible to train yourself to drive them. Get up to speed gradually and avoid spinning. If you spin you need to shut your eyes as simulators are very poor at simulating spins (they are not designed to do this).
