Hi *******:First I want to thank you for all the work you have done for all of us, you have helped a lot of others improve their FSX programs.I used your tweaking tool with the VSync fix checked and got back a cfg file that looked ok. I installed the tool’s suggestions in the new cfg file and copied it in FSX fsx.cfg. My problem is simply this,I get a blank (black) screen that should show the default AC. Also when I clicked on the Fly Now button I also have a black screen though the mouse will show the names of the gauges and other points.I’ve rechecked the cfg file for weeks now to see if I could figure out what is causing this. Also rechecked all the posts to no avail. The only thing that I thought was unuual was with the VSnc fix whereas in the [Graphic] section I have – ForcedWindowedVSync=1, and –ForcedFullScreenVSync=1, however also in [Display] –ForcedFullScreenVSync=False, and – ForcedVSnc=False. This is the only commands that seem unusual.The only thing that I’m not sure of is if the code is wrong. It is in English and looks the same as in my original cfg.I have gone through all the Posts and not found anything that is remotely like my problem. There was a problem with changing from Windowed and Full screen, but I’m not getting past the default AC screen.My OS is XP 32bit, SP2. FSX Deluxe Edition bought in Europe.Thank you in advancefor any help you can give me.ThomasMainboard- ABIT Fatal1ty FP-IN9 SLI N650 RAID/ Processor-Intel core 2 duo E6700 2.67GHz 4MB-ArcticCooling Alpine7/ 4x 1024MB DDR2-667 Mushkin SP2-5300/ DVD player-Samsung18x+/-RW silber/ Hard drive-400GB Samsung HD400LJSATA11/ Grafic and Sound card 2x 768MB XFX GeForce 8800 GTX/ LC-Power 850 Watt PFC bulk.
