I've been told for the most part SLI is especially useless with the Oculus Rift, however I've been playing with assigning Physx functionality as well as turning on SLI anti-aliasing (assuming that the type of anti-aliasing the game uses is compatible.) But I'm unsure if I'm benefiting at all. I'm going to do some testing tonight but if anyone has information on this it would be much appreciated.
For those of us who know what we're talking about, explicitly offloading Physx to your other GPU makes certain that your main GPU isn't bogged down should the occasion arise (Elite might use Physx). Also, in the nVidia control panel, you can enhance a games anti-aliasing if the game uses MSAA. If you enable that option and you have SLI you can dedicate a card just to do anti-aliasing. up to 16x, which might be handy considering how the Rifts image quality is so dependent on AA. That option is called SLI anti-aliasing. Thhhthbt.

Speaking of not knowing what you're talking about, PhysX isn't something all games just always make use of. Also, MSAA doesnt work with any game that uses deferred rendering. Finally, I may be mistaken ( doubt it) but if SLI isn't supported, "SLI anti-aliasing" won't be either.
I stand corrected, hell I even knew that. We are a ways away from SLI though. I am happy with my single 1080 but SLI support can't hurt and I cant wait for devs to start using multi projection.
I am generally skeptical of the idea of a dedicated PhysX card though. In some cases it can even give worse fps as the main gpu waits on the PhysX card. A 1080 is plenty outside of 4k.

I don't know where I implied that I thought every title uses Physx. Or how you inferred that. But that's not really the point. I've not seen any mention of anyone trying to use the SLI anti-aliasing at all, let alone in VR. I do not know that every game uses deferred rendering and that MSAA doesn't work with it. I do know that enabling the SLI rendering for Redout does improve the image but I don't see the second card rising above 10%. Also it's not clear that Redout is using MSAA. However the framerate is smooth, or at least I see no difference in performance. I'm going to look for a game that I know uses MSAA.
