We all know how difficult it can be at times to view complex 3D models with Autodesk Design Review or any other application for that fact.
Mind you, this is a problem that is widespread and not only caused by applications but many times by the limitation of the used platform itself.
We have made much progress over the years and Autodesk Design Review 2009 has shown many improvements as far as performance in the 3D arena is concerned. And yes, 2D performance was improved as part of the same.
Autodesk Design Review 2009 even offers some assistance to you to improve 3D performance.
The afore stated dialog appears when DirectX drivers are detected on the system. Several customers have now confirmed that switching to DirectX graphic drivers actually enhances the 3D performance of Autodesk Design Review even further.
You can always switch back to OpenGL, if you did accept the DirectX settings and find that it does not show improvements to your liking. Use Tools>Options>Model>View Settings.
Not sure which version of DirectX you have on your system? Try running "dxdiag.exe" through your Start>Run Windows interface. This will bring up a detailed Windows DirectX Diagnostic Tool user interface.
The shown dialog is from my own system and your own might differ, since it will display information relevant to your system.
The UI offers information but also provides some diagnostic tools under the display tab. FYI - I chose to decline Microsoft's invitation to "check for WHQL digital signatures" in the process.
Here are some links to good resources on the subject:
