Nvidia Developing Linux Driver for Optimus

The title is misleading: Nvidia is doing NOTHING to port Optimus to Linux - it's the opposite: Xorg developers are working to make it possible for a GPU to offload tasks to another GPU on Linux (and any system that ports the Direct Rendering Manager 2) without going through a proprietary interface: instead, any driver that implements RandR1.4 can be used to offload rendering tasks, making combos such as an AMD card displaying on 6 screens using an Nvidia card to generate the 3D on them a possibility, or an Nvidia Tegra using any integrated chip to render, say, a video, or, as in the present case, an Intel IGP using an Nvidia chip to render the 3D content.
And, as indicated, since the interface is open and shared across all GPU makers (RandR1.4), stuff like Nvidia disabling PhysX on systems using an AMD card cannot happen... Or at least, can be thwarted.

still cant run linux on my PC because of sli :(

otacon72Optimus graphics switching is the worst "innovation" ever to come out of Nvidia. I bought an HP laptop about a year ago that had this great technology. Too bad it never switched to the discrete GPU ever no matter what you did. Ended up returning it.K so one person had problems, so the whole technology is trash? Right....

I own two laptops with Optimus and it works fine. Except in one instance where it wouldn't switch to dedicated in that zombie game dead something.. Forcing it for that particular game worked fine though.

Without Optimus, many hours of my study would have had to be completed in my personal time instead of in-class (as my battery would have been vaporized by that load).

I would much rather a computer with both an IGP and dedicated GPU over one or the other. It just gives you the choice of having either battery life or high performance computing.
