Geforce 190.38 WHQL released, new power modes

With on-board video becoming increasingly powerful, I’m sure the number of you using dedicated cards is dwindling. However, if you do happen to be using a separate Nvidia video card, this is awesome news as you’ll now be able to make your system even more low powered. I’d be curious to know exactly what real-world effect this has, but at least their mind’s in the right place to save power and your money.

This time, the Geforce 190 family adds a new user-controlled power management setting for select GeForce 9-series and later graphics cards called called Power Management Mode. This is Nvidia’s attempt to lower power in 2D and desktop environments where full GPU performance isn’t required. However, the cards must already support more than one power state. This option allows users to set a performance level for each DirectX or OpenGL application. A little digging shows that the feature doesn’t really do much more than lower clock speeds. We had our EVGA GTX 295 Quad-SLI configuration set at 660MHz/1440MHz/1055MHz respectively, and the Adaptive Power option simply adjusted these to 400MHz/800MHz/300MHz respectively.
