I have tried to use the souped up video card drivers for Nvidia cards from people like Omega, and others. It gives a great boost in framerates with FS9. The problem however is the driver seems to lock the sim at a resolution of 800x600. And will not let me adj any of the graphics in the sim itself. If i do, it just reverts back to the way it was when i go back to flying. Anybody else have this problem ? And if so, how do you fix it ?????

Are you running FS9 in full screen mode? If not, give it a try and see if that fixes your problem. R-

Yes i am running in full screen mode....

Make sure your fs9.cfg is not set to `read only`.Allcott
