I think I found somthing that may solve some of the problems people are getting with 3d party Addons not showing up with the Anaglyph 3D glasses.What I did was reformatted my HD, and have not reinstalled direct X 8.1, and only have 8.0a version as yet.What I did find I use FSW clouds, with direct X 8.1 these clouds where not displayed in 3D, and did not see any red/Blue separation, now I do with Direct X 8.0a. It's faint of course, but there now.So wondering if Direct X 8.1 is causing 3D party addons to not be displayed in 3D? As Ido now suspect this maybe the case, but cannot say for sure.All I do know is when I had Direct X 8.1 installed I seen no red/blue separation using FSW clouds.

Thanks for those thoughts Den.I assume that you have no add-on airports as you only mention seing the difference with clouds?I have so much 'stuff' on my PC that I am not about to try and remove DX8.1 nor do a format :-), I will live with none 3D add-ons for now.
