Thank you for your help, so every one know it was the NVIDIA anisiotropic needs to be off for some reasone. But I know have perfect setting. thank you FA'...

Could be Mastiff.

Check in the advanced settings in Nvidia Control Panel and then pull up the settings for IL2.
Make sure that your settings say to overide, not compliment.

That was my problem when I did a re-install of drivers.
If that doesn't help, you can try to completely remove the drivers using Driver Cleaner Pro. Hard to find now, but if you need it, let me know.
Remove all Nvidia Video Drivers, set your display to generic.

Next runn CCleaner and do a registry check to delete any Nvidia entries left behind as well as fix any errors in the registry.
Now reboot the system and then reinstall the drivers.

That will reset all the registry settings for Nvidia and give you a Clean Install for the drivers.
