I don't want to be too negative with Carenado, but the not all fps-friendly is really starting to bother me. They should really work on that. The latest exemple is the Phenom 100. I have to use one trick mentioned in this site to have very low and just acceptable fps (around 10fps in 3Dsurround at San Francisco: rename and therefore desactivate two files that came with it). They are the worst (Pmdg 737, VRS with Tacpack, M2000C, M2M F-15E are much more fps friendly). So I just can be afraid of what the new Citation could be....
