Have an nvidia graphics card?

Have dual monitors?

Not getting the graphics performance that you expected?

I’ve got a fix.

Nvidia’s card has issues with its multiple monitor rendering. If you play games on both monitors it may get a performance boost (Supreme Commander for instance) but if you only play on your primary display you will more than likely get a significant decrease in performance.

Go to this setting
Nvidia Control Panel > 3D Settings > Manage 3D Settings > Multi-display / mixed-GPU acceleration

Set it to
Single display performance mode

Apply the setting change and start up your favorite game.

Quake wars went from 6FPS up to 60FPS by just changing this setting.
Friends of mine have reported less comparable results, but results none the less.
