I have an ATi Radeon 2600XT and I am running Windows 7 Ultimate Edition 64 bit.
When I go to hardware acceleration (Display > Resolution > Advanced - not sure of the exact steps but been there several times), the "Troubleshoot" button, from where the hardware acceleration settings can be modified, is greyed out.
This is a common problem it seems, but I cannot solve this. I am running the latest CCC drivers
To make things even more confusing, I used to run VMWare Workstation 6.5 and Windows Server 2008 R2. I could happily adjust the hardware acceleration setttings (had not updated the ATi drivers but VMWare uses its own display drivers). I then got VMWare Workstation 7.0 and I could not adjust hardware acceleration.
Any ideas how I can resolve this?
