Despite the fact that Windows Vista is a resource hog, the fact of the matter is that feeding too much resources into the latest operating system from Microsoft can be just as bad as not giving it sufficient horsepower. The Redmond company has informed of a scenario where users go all out and invest in a high-performance video card just to be disappointed with the results.  According to Microsoft, this time it's not the hardware, and it's not the drivers, it's all Windows Vista. High-end graphic cards with multiple GPUs do not integrate into normal parameter with Vista resulting in poor graphics performance for the system.

"You have a Windows Vista-based computer that uses a high-performance video card. This video card uses multiple graphics processing units (GPUs). In this scenario, the computer's graphics performance does not meet your expectations," Microsoft described the issues adding that "this problem occurs because the operating system does not forward driver-render requests to the secondary GPU."

Microsoft has failed to reveal a list of affected products, which seems to point to the fact that the problems are isolated. Both the 32-bit and the 64-bit editions of the operating system are affected. Still the Redmond company did produce a resolve, and the solution is in place since the end of June 2007. However, end users must contact Microsoft directly to get access to the hotfix.

"A supported hotfix is now available from Microsoft. However, it is intended to correct only the problem that is described in this article. Apply it only to systems that are experiencing this specific problem. This hotfix may receive additional testing. Therefore, if you are not severely affected by this problem, we recommend that you wait for the next service pack that contains this hotfix.
