I just got my CV1 yesterday and use to use SLI for the dk2 months ago before I sold it successfully. However direct mode and timewarp is out now. Timewarp seems to make things slightly blurry or is this my imagination. Does direct mode work with SLI for CV1 like it use to work for extended mode for DK2? If so what settings are you using and are you using multimonitor performance or single monitor performance in SLI settings? I am expecting very few SLI users out there but would love to hear from you all. Mods do not through this in the general SLI thread as this pertains to SLI for VR. I don't want to read though tons of pages because you all think everything belongs I one thread its getting old.
Any successful CV1 SLI users out there ? Mods PLease do not throw this in the general SLI thread.

SLI is not supported in VR. Nvidia's new VR SLI needs to be supported by the game developers. It also needs a pascal card and DX12. I wouldn't count on too many games using it for a while and as it is not an AMD api as well, I can't see it being adopted by very many developers As games developers write to the majority which would be single GPU users.
If I've read it properly SLI users have had to disable it in VR in some cases. AFAIK

I did have two 970GTX cards until recently- and no, SLI didn't work. Extended Mode allowed the headset to rely more on nVidia's settings and I could get a few titles shoehorned into working. However, not since the the Oculus runtime used Direct Mode (which is the default now on 1.3 of course). And not with ED, and as dogbite says above it'll take quite a lot of work to make a title use it. Hence I'm currently using a single 980ti instead having bought out of SLI- too many titles are simply not going to use it to make it worthwhile, especially with VR when neither CV1 or Vive runtimes utilitise it either.

Can confirm that SLI does nothing at the moment but add problems when playing this title. I can also confirm this because my second GTX 980 is now sat on my desk gathering dust

Sat on your desk? Metaphorically speaking?
You can just disable SLI when playing Elite in VR? (That's what I have to do when I want to play Elite in VR, I've got two GTX 970s)

It may not cause you problems with 2 cards installed but there is no advantage to it in VR. It is NOT supported in VR games or by Oculus or Vive right now. Some have complained that it screws up ATW but can't confirm that.

I was talking about ED on my DK2 here: i can say that i can't run the game in VR with SS*2 on 1 card but on 2 card i can and afterburner does show that both card work (gpu load and SLI sync), surely it does affect latency but i never really felt anything off since the ATW inclusion in runtime 1.3. Still would like to know why (tech side of things) on ED going from DK2 to CV1 made SLI give worse performance for some users

If I understand what I've read, since the Oculus 1.3 runs in direct mode you won't see any performance benefit from sli. There is a crazy amount of arguing on how much benefit came from sli with earlier runtimes over at the Oculus forum. What I was getting at was current runtime and direct mode shows no benefit. You say you are on 1.3 with your DK2 -pull 1 card and see if you lose any performance . Apparently you shouldn't but don't have sli so I cannot confirm. Ask Oculus or read their forum or google the question. There are a fair amount of sites discussing SLI and VR

I can assure you that disabling SLI (so runing on one card) reduce my performance playing on ED (just confirmed it play launching my game with same settings planet side = judder fest ATW can't cope). The big problem with SLI is the sync limit, if both card aren't sync there is not much gain of FPS side and it increase latency. if both card don't run at the same clock then sync is not achived. I got rid of that by using evga precision tool to permanently Kboost both of my cards so that both clock are the same.
A talk about my experience, others may differ with hardware quality and user settings. Still feel sorry if CV1 don't wrok at all with SLI beacause running the game at SS*2 in DK2 got rid of 90% aliasing, looking at an orbis station is just marvelous....

What cards are you using? What are your FPS? Just curious. So you are saying you get better performance in SLI with your new CV1 but that ATW is causing judder? Then your query might best be dealt with at the Oculus forum. I and many others would certainly like to see what you can learn from them. Standing by. Good kuck

Sadly no: english isn't my native language so i think i may have said something wrong. I do not own a CV1 (oculus don't ship worldwide) but on my DK2 playing ED with lastest beta and 2*970gtx supercloaked i got 75 FPS (DK2 here) in space, near planets. In station it goes to 66fps and then ATW kick in and give smooth vision, same thing near planetary instalation (50+fps) all that with SS*2 ingame and some options in low.
For the CV1 i saw some users saying that SLI didn't make any change so going from 1 screen (dk2) to 2 screen (CV1) might be the problem of added latency using SLI with CV1
Well ok then. I was responding to the original poster of this thread's question " Any successful CV1 SLI users out there " when I said SLI is not supported. You say you get increased fps with SLI but have judder on your DK2 with 1.3 so really then it doesn't work for you either in any meaningful way unless your willing to put up with the judder but again I was addressing the original post. If ATW is causing the judder for your sli then it would fall to Oculus to remedy I would think.

Nope, it's on my desk. For the past 3 or so years I've pretty much only played VR games, even the Witcher 3 kept my attention for an hour at best. As SLI causes so many issues with Oculus 1.3, ATW judder, games not booting etc I took my second GTX 980 out of my machine. No point having it installed if I'm no longer using it. I need to get around to selling it really.
+1 for OP, Thanks for the honest/detailed replies on the SLI status of Elite and CV1. I was looking at some more performance for CV1 and this thread answers whether to SLI or not..
(I had 970SLI for DK2, and later went to 980Ti for a better experience, although SLI was helping with profile tweaks it wasn't as good of an experience as the single 980Ti).
Thanks!
