For me it seems to be stuck on x2 while having 80-100fps, so saying dependable on the PC performance it's not true. There has to be config in some file that we can edit which will allow us to control the speed by the sim and not the aircraft, otherwise what's the point of flying long haul? I would be more than happy to have ability to manually control the simrate. Not many people have 12hr to sit in front of the PC.
