Hi guys, nice forum you have going here. Been lurking for some time now. And a very special thanks goes out to ******* for making my FSX experience better than ever. I have tried this mod on my 5870, and the the sim is smoother, no doubt. Though the fps has not improved the sim feels much better. Very nice. My "specs":Using CCC Super Sampling AA16X AFBP=0Affinity Mask=14HighmemfixForceFullScreenVSync=1Shader Mod 3.0EnbseriesREX2PROLBLEM: I get black bars/spikes/artifacts on & off. They come and go. I can get rid of them by turing on/off the menu bar (alt). Its always the same type, a black "spike" in front of my view that disapears if I pan aound. Otherwise the IQ/FPS is excellent!The problem showed up AFTER this mod.Any suggestions would be highly appreciated!
