Windows Server 2008 with Nvidia GeForce 8600GT - poor performance when using aero
I have a computer running Windows 2008 Server Enterprise (SP2). I have installed the Desktop Experience feature and activated the Themes service. From the Nvidia website I've downloaded the latest drivers for Windows Vista x64 and the they've installed without any issues (I assume they are the best for my OS, since Nvidia does not provide support for Windows 2008). When I activate Aero, the performance is really bad, I have issues even with the scroll in Firefox. If I run dxdiag everything seems to be fine, it says that hardware acceleration is on. Do you have any ideas on what is causing the performance issue and how to fix it?
