Have you tried using ingame super sampling? instead? if this works and DSR does not, it would seem to indicate that its a driver issue rather then game issue?
Elite Dangerous, the DK2 and SLI discussion thread.

Nothing wrong with SLI whatsoever. Works perfectly and has been for years. Do not mistake nvidia SLI with AMDs CFX, as Nvidias works so much better.
I played for an hour hunting bounties in a resource extraction site (nice haul too, pulled over a mil without much effort)
The frametimes are actually much more worse than I initially thought, averaging 26-28ms compared to 13-15ms with a single card.
Running SLI does not solve supercruise stuttering and there is a slightly noticable judder which isn't there with a single card.
Its still playable but single card at these clock settings is definitely a nicer experience.

Another hour gone, damn, I should be sleeping.
SLI off this time. With SLI on, I feel like I'm playing a game, with it off, I feel like I'm wearing a helmet in a space ship. The frametimes are dramatically different, even with the judder in supercruise the frametimes are still better than SLI normally is.

What is your pre rendered frame VR settings in Nvidia control panel? Setting it to 1 may help with latency if it's not already on 1
My driver 353.38, adapative sync on in NVpanel and average frametime between 14 and 16ms with SLI enabled.

Already done. TBH I don't think frametime is a good indicator of input lag. How does it feel? At the title screen my frametimes are 14-15ms but there is a noticable lag between head movements and what is on screen, this simply isn't there without SLI. Framtimes also go up when in game vs at the title screen which doesn't happen without SLI.

Sure, SLI works great however currently for VR single card is best (this is the VR sub forum after all). Much lower input lag which is why I said use a single card if it's fast enough.
On my current setup the only advantage between SLI on or off is being able to run 2xSSAA vs 1.5xSSAA with the tradeoff being higher input lag and frametimes (which makes me nauseous and gives me eye strain).
I'm pretty sure when VR hits mainstream and we can run retail HMDs this issue will be gone.

He is talking about DSR + SLI + DK2, it currently doesn't work.
Can you post your system specs? are you overclocking your graphics cards at all?
If you look at the graphs I posted, my card is spiking up to 95% while in a station (at the end before quitting the game), this is with everything at the highest setting and 1.5xSSAA and as you can see the framerate is locked at 75FPS (apart from the SC stutter, but as you can see this does not correspond with a spike in GPU usage) so I'm curious as to why you can't run the game at max settings on a single card.
Did some more test this morning:
SLI OFF: i did notice some bloom on text that wasn't there with SLI on, frametime between 14 and 16ms, very smooth head mouvement but my computer can't get 75fps anywhere with in game SS@1.5
SLI ON: no bloom on text, frametime between 14 and 16ms, less smooth head mouvement but my comp will get the constant 75 fps anywhere with in game SS@1.5
Once you're used to the very smooth head mouvement of Sli off i can understand that you don't want to go "back" to SLI on, but sadly i need to made the choice between (super smooth tracking and average look) and (average tracking and super look) :/
This is odd, I have disabled bloom in the graphics options. With bloom on it usually only shows up on the HUD when you have the HUD brightness up high.
Have you tried DSR on single card instead of SSAA in game? 1.5 DSR with smoothness set to around 25 looks pretty good with slightly less performance hit, the only problem is it won't work with SLI.
Yep tried it, but need to set all option to low and shadow off in order to have good 75fps in stations (in the anaconda bridge, perhaps it's too taxing for my gpu alone), but like Palmer luckey said: Smooth>look in the rift
FDEV please add VR SLI support
Dear FDEV,
Please, add VR SLI to Elite. It makes VR performance soooo much better. Pretty please with a cherry on top.

A recent talk on VR SLI
Here is a recent experience report with it in CryEngine
I have to admit the recent live stream with David was a little disheartening to me. It sounded like David wasn't aware VR SLI even existed
The same applies to AMD's liquid VR as well. Please, spend some time to implement this FDEV. The VR experience of Elite is fantastic already, but it is a shame you can't use it with SLI setups.

I installed a second GTX 980 yesterday, manager to run 2x SS with all settings on high in 1.4 and 1.5x SS in Horizons beta 3, again with all settings on high other than the terrain settings which I put on low. Sli certainly made a large improvement for me! Would be nice to see game works support though for proper VR Sli.
Well you can nearly do that with a single GTX 970. If you're using SDK 0.8, as far as I can see leaving SLI enabled and trying to play results in it dropping to a sort of compatibility mode as opposed to earlier drivers where it just broke completely in direct mode.
If you want to see this in action fire up MSI Afterburner or something like it and monitor the GPU utilisation. One will be doing all the work and the other will be mostly idle.
Can confirm the same for me.
I couldn't even enable SS above 1.0 with a single GTX 980 without dropping the VR Quality slider some... From what I have read here 0.8 runtime offers no real improvements.
