Will the 980GTX in SLI work out of the box with DK2?

I read an article that states that nVidia has worked with Oculus to ensure that if you run two 980's in SLI, it will use each card to render each image to the eyes.

Any word if this will work out of the box with DK2 Direct mode? If so I'm going to take the plunge.

Lastly, NVIDIA’s fourth and final latency optimization for VR Direct is VR SLI. And this feature is simple enough: rather than using alternate frame rendering (AFR) to render both eyes at once on one GPU, split up the workload such that each GPU is working on each eye simultaneously. AFR, though highly compatible with traditional monoscopic rendering, introduces additional latency that would be undesirable for VR. By rendering each eye separately on each GPU, NVIDIA is able to apply the performance benefits of SLI to VR without creating additional latency. Given the very high performance and low latencies required for VR, it’s currently expected that most high-end games supporting VR headsets will need SLI to achieve their necessary performance, so being able to use SLI without a latency penalty will be an important part of making VR gaming commercially viable.

Bar10 - it's hard to say. I saw in another article that not all the new stuff is implemented in the 344 (newest) driver. I bet VR-SLI is though but can't promise it.

But the articles out last night all say that VR-SLI has each card rendering each eye view specifically for HMDs like the Oculus so if it doesn't work out of the box, it will very soon.

Here is the link saying not everything is in the 344 driver yet but they don't include VR-SLI as not being available.

while there isn’t the obvious jump in performance that some people expect with new architecture, Maxwell opens up access to new tech that comes along with the 980’s development, like DSR and MFAA. (Both of which I haven’t been able to test yet, as they’re not part of the 344.07 driver; however, from what I’ve seen in demos, those two types of tech do seem to help increase visual fidelity.) So that could bump up how much of an edge the 980 has over the 780 Ti.
But... but... but... I just NEED to know about the Baba! The Baba has me hypmotized! :shock:

Any news on VR SLI and other features for the lucky peoples owning 2 GTX980.

no, still just 344.16 ..you will undoubtably hear people screaming about awseome vr support when it arrives
i7 skylake, EVGA Classified, 2 EVGA 980 sc's, Thermaltake TR2 RX(1000W), 32GB DDR4, Win 10 on an SSD

Thanks, I hope I will be screaming too...

I hope its backwards compatible with Kepler. People have already tricked the 980M drivers to bring DSR to Kepler and Fermi. Completely artificial limitation! Hate the way Nvidia does that stuff because their cards are 100% otherwise.

I've had mixed results with the current driver, sometimes it will utilize both others it barely utilizes one.

Nvidia are notorious for artificial locking, so I would not be surprised the least bit if the VR features are only 900series compatible. Take a look at their 3D TV drivers for example...they claim that 3dTV can only do 24hz @ 1080p 3D due to hardware limitations, but one EDID overwrite to trick it into thinking you 3DTV is a monitor approved by Nvidia, and you have 60hz 1080p 3D gaming...disgusting really.

Downloaded new driver last night, in reference to the 900 series cards release notes did not mention anything about VR. SADFACE.

nVIDIA. MORE LIKE NO-VIDIA. For you. You know? Like, no video.

...tumbleweed...

*cough* Back to work then.

Hey Wire, I just checked the NVidia site and it looks like they are still on 344.16 even in the beta section.

Did you get a newer version?
