Hey cadsters, Here is some news that has come out of Siggraph 2005. I have cut/pasted this from the discussion boards. It sounds like CAD graphics might take a performance hit with the Aeroglass implementation in Vista and that we could do our bit by voicing objections through Solidworks on behalf of 250,000 users.regardsneil-----------------------------------------------------------------------------------------------------------------------------Microsoft's current plan for OpenGL on Windows Vista is to layer OpenGL over Direct3D in order to use OpenGL with a composited desktop to obtain the Aeroglass experience. If an OpenGL ICD is run - the desktop compositor will switch off - significantly degrading the user experience.In practice this means for OpenGL under Aeroglass: a.. OpenGL performance will be significantly reduced - perhaps as much as 50% b.. OpenGL on Windows will be fixed at a vanilla version of OpenGL 1.4 c.. No extensions will be possible to expose future hardware innovationsIt would be technically straightforward to provide an OpenGL ICD within the full Aeroglass experience without compromising the stability or the security of the operating system. Layering OpenGL over Direct3D is a policy more than a technical decisionWhat can you do? 1.. Write to your preferred ISV, hardware developer or OEM and tell them to bring this up with Microsoft (e.g. 3Dlabs, ATI, Intel, Matrox, NVIDIA, HP, Dell) 2.. Bring this issue up on other developer and tech-related web sites. If you have a personal blog or podcast, talk about the issue there. Windows Vista might end up being a great product, but not if OpenGL is crippled 3.. Post your comments to this message board (please no Microsoft bashing - Just make it clear that Windows needs to stay a great platform for the OpenGL API and offer any suggestions)

Vista should be the new windows OS which is due to come out on 2006 (until a few weeks ago was named with the code name "longhorn").As for Aeroglass - I too, would like to know what it is.

OpenGL under threat?

I didn't know that ! In that case, you can report back here for those of us who are too lazy to keep up with two sources of SW information. I actually gave up reading the forum before I gave up paying support.
