Simon, I haven't noticed any performance degradation (similar to what you describe) on nVidia hardware. It sounds like maybe the radeon driver does ok drawing alpha quads (or quads with an alpha component) from back to front, but perhaps there is an inefficiency in the pipeline when the alpha

In real life, I've been having a hard time with my landings on the circuit ('suck' might be the most appropriate term). Practicing with FlightGear has helped a bit, but it didn't really feel right. When I'm landing a real C172, there are almost always wind gusts, turbulence, and other nasty
