Did some searches and could not get good info on the following.1. After simming for 20-30 minutes or on approach to a complex airport the frame rates gradually go down to 1-2 FPS...then if you Alt-Enter the frame rates go back up to MY normal 15-25..! I usually run in full screen...and I run all the complex panel/aircraft combos. PIC, PSS, and Dream Fleet. Happens with all and freeware also!2. What is it with the strobes at the airports and on tall towers during day light hours they send out a black splinter or wedge into the sky looks awful!Any ideas!!!RegardsTony

From inside FS, go to the settings/display/hardware menue and make sure you have at least enabled Bi-filtering or the prefered Trifiltering.Paul
