No not frame rates again!In FS9 frame rates are generally tolerable, good in the cruise and not so at the take off and landings. I use only Wilco buses, Pss757/777 and detailed airports with MYT2006, ASV6.5, UTE/UTUSA. I have just noticed after years of running FS2004, that in the cruise or taxi on the ground,jumping from cockpit view to spot view and pressing the ALT key twice, the frame rate increases by ~20%.Changeing views back and to it goes again until I press the Alt key twice again. It is not hardware as I have just changed machines with a fresh installation. It was the same on the old machine.Any comments welcome. Thanks

Texture loading.

Yes pressing Alt-Alt sometimes "gooses" FS9 to finish loading textures, the loading process will hamper FPS since it consumes CPU time.

Thanks for the reply, but what can be done to make alt/alt unnecessary
