Cessna421 or SenecaV?

I do alright on my P3/800 as well. One secret is found in leaving reflections off. And reflections only seem an issue in the external views. From the cockpit, I've never had a fps impact....but....I've noticed that the GPS can cause a stutter when the window is open. It is best to close it on final. That may improve framerates in marginal systems...-John
