On our new Dell Workstation there is a ATI Radeon X1800 Graphics Card. On Windows XP it did perform very well but after installing Windows Vista it is SO SLOW.
OpenGL diagnostic told us:
OpenGL Version 1.1.0
Renderer GDI Generic
Vendor Microsoft Corporation
On WinXP this meant that we were not using hardware accelerated OpenGL
WHAT DOES IT MEAN under Vista? Should we look for a better driver or we will not find a better solution for all you know about OpenGL & Window Vista?
Wasn’t Vista supposed to have a ‘Direct3D’/OpenGL wrapper instead of the ancient GDI wrapper.
Looks like the promised feature was dropped in the ‘final’ version …
