...frames.I have a P4 2ghz, 1024 ram, 128MB Geforce FX5200 Ultra.The way I have my settings the PSS A330 runs at like 15-20fpsand the RFPB runs from 15-20fps, and like 7-10 in big towns

Without the ram, you'd hurt, but since you have plenty to deal with the bigger footprint, you should be happy enough. It is no worse then any other complex addon, they all require a little give and take at the detail end of the slider.Ray

I find that the PMDG yields 3 to 5 FPS better than RFP. I don't have the airbusses.__Josh
