Have CFS2 installed on system with Rage pro 120.

With 1.4 Gh and 256 Ram all works well on full settings.

Recent prob is that when I initiate any mission or aircraft, the graphics start out fine, but within a few seconds the gunsight and scenery go very blurry. (Gunsight unusable).
The panel (virtual also) remain good.
If I go to external view the stock planes have virtually no textures at all, just flat colour (blue in F6f) but addons do have textures.
Some times it will come good for a short time and then go bad again.


What the hell is going on?

Thanks 

P.S. Everything is fine and as usual on CFS1 & 3. This is only happening on CFS2.
