I tend to get frustrated which doesn't help and my time on the sim usually comes at the end of a long work day, so I am actually often quite tired when I get into the seat and that is a big issue to. I find MX5's I was much better with because I can relate more to their dynamics having raced one, though the base set up is crap. Likewise I settled into the AMG GTR as I drive one and though it was different there are still some common themes. Same will the 911, RSR is hard to pedal at pace but it is like a 911, again something I have actual reference points for.
