Hello,

I've been wondering if I should try enabling the dual-graphics mode (not CF or SLi) for my computer and I'm requesting help to get some things clear.

What I mean is enabling the inbuilt CPU graphics + discrete graphics, so when there is no need to process graphics, computer would be in 2D mode and almost turn the 6950 of mine off.

I checked and it's possible to set a certain amount of shared RAM to allow the integrated graphics to use. As I just use about 5-6 GB of ram max, I guess allowing it to use 1024MB of my RAM would be no problem, right?

I'm talking about LucidVirtu technology.

How much power could I be saving with this feature enabled? As does it increase the power drawn by CPU and does it bring the graphics card's power draw to near nothing?

Thanks

It brings them down to idle levels and that's it, no quieter/cooler/power-efficient/etc.

I don't see the main purpose of Virtu as power-saving feature, but to allow you to encode using iGPU.

Yeah, just checked a review at [H] and enabling the LucidVirtu actually lowers the FPS in games about 2-10%, so I definitely won't enable it.

It only lowers it if you use iGPU mode so it engages the dGPUs when gaming, I saw ~3%. I have mine in dGPU mode so I can use the iGPU for encoding etc, there's no adverse impact this way.
