1. OpenGL® on Windows Vista™
Neil Trevett, NVIDIA

2. Good News! This time last year…
The plan for OpenGL on Windows Vista was to layer OpenGL over Direct3D in order to obtain the Aeroglass experience
The situation today…
OpenGL accelerated ICD now fully supported under Windows Vista
OpenGL works fully with the Aeroglass compositing desktop
Performance and stability will rival Windows XP by driver release

3. The Details
Direct3D and OpenGL now use common window manager interfaces
To allocate system resources and send rendering commands to the GPU hardware
The Windows Vista CD does not include ICDs
Driver with ICD must be downloaded from web site the same as Windows XP
Windows Vista Beta2 ICD available today
From NVIDIA at
Drivers will soon be available from ATI – watch this space
Microsoft has a layered OpenGL over D3D for basic functionality
Only used if no ICD is present

4. Two Things to Watch Out For
Hardware overlays are not supported
Hardware OpenGL overlays are an obsolete feature on Vista
ATI and NVIDIA strongly recommend using compositing desktop/FBOs for same functionality
Stereo is not currently supported – will be limitation on first Vista
ATI and NVIDIA are working with Microsoft to cleanly build stereo support into driver model
If you need stereo – let Microsoft know

5. Thank You! Thank you to the OpenGL community Thank you to Microsoft
For helping to communicate with Microsoft the need for accelerated OpenGL on Windows Vista
Thank you to Microsoft
For being responsive to market needs
Together we can now provide the best user experience on Windows Vista
