I also thought that Brendan so I upgraded to a MSI 970 and its still there.  I've installed my system (W7 64bit) from scratch and even in default P3D its still an issue.  My old trick of using another G3D.dll does not work as the old one I used in 2.5 is not compatible with 3.0.

 

Like I said I just learn to live with it and keep on flying.

Which version of prepar3d did you copy the G3D.dll to prepar3d v2.5?

It was the initial 2.5 release.  Unless you saved the original 2.5 before it was updated you will not have the g3d.dll that will fix the issue in 2.5

 

I looked under my licence info at LM and the only file to download for 2.5 now is the updated full version.  I used to keep a backup but with 3.0 now I think I deleted mine.
