Sorry to hear that, what kind of PC specs do you have? All the key assignments are in the settings menu...pretty easy to figure out although not as plug and play as MSFS...I may have a slight edge on performance due to Linux which uses less resources out of the box...Look into tweaking whatever OS you run...NickN has a good set of tutorials for XP & I think Vista here....
I cant run this sim on full settings and I only bump up the autogen for screen shots, but I still maintain good FPS unless I get crazy with the autogen, AA and vehicle traffic
