http://forums.avsim.net/dcboard.php?az=sho...topic_id=136178 This is an unbelievable tweak, probably THE BIGGEST TWEAK IMPROVEMENT I HAVE DONE TO MY COMPUTER. This has allowed me to go max sliders on EVERYTHING in 2004 and get a rock steady 30 fps. I may drop 2-3 frames going into an airport like KSFO, but that ain't nothing. If you have a Nvidia based card, this will astound you!!!!!!!!! I just can't say it enough, this is a major video tweak. Un-friggin' real!!!!!! Hope this helps some of ya out!!! Let me know if you see any difference. Harry CVA5812

No difference here - cause I run a Farzenhuuven video card with full duplex modifications and double slant bypass modes.DS CVA3339 / UKD149System: Attlon 900 McW Hamster/Gerbilized Quantum Accessible 55Gig Iodized-Encrusted Four-poster with Mega-brill Farzenhuuven http://vatsim.pilotmedia.fi/statusindicato...tor=OD1&a=a.jpg

Bill, what exactly did you do? I have followed that thread, but it is, well...a bit difficult to follow. I have tried a few things and saw little or no improvement with my nVidia Quadro4 700XGL.Lee Hetherington (KBED)
