GTX 1080 revealed!

Nvidia is live-streaming a reveal event to show off the new GTX 1080 tomorrow night (Friday May 6 9pm EDT). (Source)

I know a lot of us here have been waiting for the Pascal line-up, due to the graphics-power-hungry nature of VR. If the performance increase is significant, I'm going to go ahead and upgrade my GTX 980. I have a second PC that I recently built that's using an old GTX 660 Ti, so it will take the 980 when my main box gets upgraded.

Anyway, just thought you guys would like to know!

DK2, CV1, Go, Quest, Quest 2, Quest 3.

Yes the 1080 has a nice performance upgrade, but it may not be worth upgrading from a 980ti for general gaming,  BUT what people are forgetting is the possible VR optimizations in these new gpu's that could completely blow away the 980ti.  The question is what kind of hoops do developers have to jump thru to access these VR optimizations.  Some say,  only DX12 and NVGameWorks can apply, but I'm not so sure.  Since there is new hardware on these 1080s to accomplish VR optimizations like multi projection, it could be accessible by a knowledgeable coder.



As far as I know, Simultaneous Multi Projection has been possible since the release of Maxwell 2.0. Back then, Nvidia were touting it as Multi Projection Acceleration and devs were using Multi-Res Shading to improve 4K renders, as well as VR.

Basically, this kind of tech is possible on both Maxwell 2.0 and Pascal. Now, whether Nvidia have altered the name slightly (from Multi Projection Acceleration [MPA] to Simultaneous Multi Projection [SMP]) to help market the 1080 as some kind of VR specialist card, I don't know. But I'm pretty sure that Cyan, the Myst creators, who're developing Obduction, and using this tech in that very game, have categorically stated that SMP is working on both 9 and 10-series Nvidia GPUs.

If this is no longer the case, I do hope Nvidia aren't going to disable such features at driver level, just to shift the 1080/1070. It wouldn't be the first time Nvidia delayed "new" tech from being enabled on capable previous GPUs.


Yes the Maxwell can do a version of this new tech, but the Pascal cards have new hardware on the card that much improves multi projection etc.

 Based on general performance there is no need to update a 980ti, BUT the big questions that we don't have answers too right now is the 1080's VR performance.  Any game optimized to use the 1080's multi projection in one pass would blow away any 980ti in VR.

I may upgrade my 980ti only to take advantage of EVGA's upgrade program, if the new 1080's come out in the next month or so.

My 1080 should be in tomorrow, as I pre-ordered.    I was only able to reserve 1 as there is a very large back list, so SLI won't happen this time around but I will report my findings and do some benchmarks once I have a moment.
