NVIDIA SLI and ATI CrossFire are designed to provide scorching dual-GPU 3D goodness. Only trouble is, Windows Vista may not have been cooperating.
The Solution for the "Dissing Your Second GPU" Blues
X-bit Labs reports today that Microsoft has released a fix for systems that ignore the second GPU. According to Microsoft Knowledge Base article 936710, the solution involves replacing three files (D3d10.dll, D1d10core.dll, and Dxgi.dll). Updates are available for all Vista editions, both 32-bit and 64-bit.
It's going to be interesting to see what happens to Vista gaming performance after the updates are made.
