GTX 970 to SLI or not

sorry I'm a bit dim when it comes to graphics.

I tried out downsampling last night using my GTX 970 card. The graphics look so much better.
I noticed that I get a steady 60fps which is as much as my TV supports, I also noticed that the GPU fans are never on so the card looks like its handling every thing just fine.

With everything is working perfectly in mind....

1) if I invest in another GTX 970 and SLI - will I see any difference?
2) I have just ordered a DK2. I see posts saying that the DK2 doesn't support SLI so not sure if I really need another card

Any help appreciated. I'm tying to justify the expense of a new card and get a feel for what it brings me.

Hey man. If you already have steady frames, then no need for another card. I mean you're not going to see the benefit if your TV is only 60Hz.

Actually I believe the DK2 outputs 75Hz soooo a second card would helpbridge that gap . But I would wait and see first. Try it out, and if you want more frames then go ahead and get a second card.

Vsync is known to suck up a lot of frames.

I have a single 970 and a dk2 and I can get a steady 75fps pretty much everywhere in the game. Two 970s in SLI will give you faster framerates, but as I understand it (for the time being at least), you'll get a larger motion to photon latency, so a slightly longer time between your head moving and the world reflecting that. I don't have SLI though so I don't know how much of an issue it is. If I were you I'd probably hang on till you get your DK2 and try some things out. I'm finding a single 970 is good enough for the DK2.

Very good advice, it took me ages messing around with various settings for my dk2, see how far you can push DSR in nvidia control panel makes a big difference.

There you go OP, best advice is in this paragraph. However just be aware your frames may differ since not all system/hardware configurations are the same. But it looks like a piece of cake.

I am currently using a 6990 but for some reason since beta 3.9 I am in low persistant mode constantly now, prior it was butter smooth. at least I think its low persistant mode when i move my head I see double images like it splits into 2 images when I move my head.

Will order a 970 as soon as funds permit.

Hi there -- I am running 2 x GTX 970 in SLI on a i7-2600k @ 4.6 ghz. When I run one GTX 970 i need to largely set things to low to ensure a consistent 75 fps in all situations on the rift (even heavy stuff in a station). I've run a framerate monitor and you will get drops below 75 fps with medium default settings and only a single 970. With a second GTX 970 and SLI enabled, I can run high on everything - except I disable Blur and AA of course.

I'm running the DK2 rift in extended mode for reference. The latency may be there for a second GTX 970 but i'm not really perceiving it vs. a single GTX 970. I also expect the VR SLI driver to become available in the next few months which may address the latency issue.

The only problem I have is i can't run DSR (i.e. render at 2560x1440 then downscale) without flashing effects on my 970 SLI setup. Not sure why yet, but this is a recommended way to make the text easier to read in the rift. I'm using MSI Gaming G1 GTX 970's.

Hope this helps..

A single gtx970 should easily slam elite dangerous. If you have to turn everything down to low with one card you may have a bottleneck or a faulty chip. How are you temps?

I'm running 2x980's and with everything maxed out except AA(off) and Ambient Occlusion(Off) and at 2560x1440, I can get 75fps everywhere except the occasional super cruise stuttering. Setting environment quality to Medium eliminates that. I was having trouble running the same settings at 1080p with SLI off, so SLI definitely helps and I don't see any noticeable latency (although I know it is there due to the SLI still using AFR).

I don't know what difference 2x970s vs 2x980s is but if you have the money to spend, SLI definitely helps, if only for the 2560x1440.

A single GTX970 should be able to run the game on the DK2 with High settings as long as you;

Drop Shadows down to Medium or Low
Disable Ambient Occlusion
Disable AA

You'll get occasional stuttering, though thats mostly due to the game stuttering itself as it loads/generates assets.

I dont agree at all, a single gtx 970 cannot provide a steady 75 FPS in all situations. You will get frame drop in crowded stations, ressource extraction site, and supercruise if there is too many npc, even if you have everything set to low. Right now the game have unexplained frame drop not related to gfx (mainly npc related). I already warned players about this in some other thread. Don't believe people how surely not checked their FPS ingame. The cake is a lie ;-)

So, just one piece of information. While I agree that SLI does not work with the DK2 in general. Elite Dangerous seems to be the exception. I have been using SLI with the DK2 in Elite and it has been running fantastically well. That being said. SLI will be supported in the future. Both AMD and NVIDIA have announced SLI solutions that will work well with the Rift.

I have the same card and had this flickering, I think it's because your dk2 is outputting at 60mhz
Set dk2 as primary and it should be flicker free
