OOOOOOOOOOOOPS!!!!!..what happened????
Maybe your video card is overheating all of a sudden... for some reason. Sort of looks like it.
Blow away your FSX.cfg and restart FSX.
When you uninstalled, did you check if the folder containing the "shaders" was gone as well ?
I mean, since this stuff is "compiled" on first lauch, maybe it needs to be recompiled to work with another video card ?
FSX SP2 on a fresh Windows - working.
Relief - indescribable.
Someone in a geman FSX forum said that the /3Gb and /UserVA switches might have had something to do with this.
Time for investigation...
