Does Elite Dangerous support SLI for two graphics cards?
- Thread starter AnArmyOfBeaker
- Start date
2 x 1070.
SLI caused stuttering for me in Odyssey (docking was particularly noticeable). Also noticed very low frame rates as assets loaded, the frame rate then increased. as I played in the scene.
I disabled SLI completely in the Nvidia panel and the stuttering went away. So fo me it was better without.

Honestly - it's decent!
There are some frame drops when things get a little 'busy' (In starports, planet surfaces etc) but it's perfectly playable!
(About the only thing in Odyssey that really brings my system to it's knees - is fire. BIG frame drops when I look at fires...but there's not many of them!)
I was running in Low - but i've up'd the quality to Medium - it's good! o7
Fire kills my GTX 1080 as well. I have tuned it and now get about 60 fps in the stations. I have not been near fire since I tuned it, so maybe I'll try that tonight.
I have some ram coming today, I doubt it will help, I just decided to go with more because it was only $89 to take me from 16gb to 32 so why not.
No, they still have practical gains on hardware and software that supports them. They are becoming obsolete and unsupported though.
Well, the tuning helped some what, I'm getting around 55 fps, until 
shows up... It drops as low as 14fps. 
shows up... It drops as low as 14fps. Both SLI and Crossfire are no long suggested or supported by either Nvidia and AMD. They both determined that the cost to benefit ratio was horrible and gave up support about a year or so ago.

AMD Bids Farewell To CrossFire After 12 Years, Retiring Brand In Favor Of mGPU
AMD revealed today that it no longer refers to multi-GPU support by its long-standing Radeon brand known as CrossFire. This revelation came via PCWorld's Brad Chacos, who was curious as to why Crossfire wasn't mentioned in the company's latest Radeon Software 17.9.2 drivers. He proceeded to...

NVIDIA Ends SLI Support and is Transitioning to Native Game Integrations (read terminated)
NVIDIA on its website is listing a new support entry, and while diplomatically written, if you read through the lines, it says SLI support has now officially ended....

The 3000 series cards cannot run SLI in DX11 games at all. There is no implicit SLI support on Ampere at all, only explicit multi-GPU rendering with NVLink.
Older cards can still scale pretty well in some cases with SLI, but there is no longer any official support from Frontier or NVIDIA.
I run two 970 GTX's in SLI.
And, I gotta say, in Horizons - It was amazing. Framerates were (are?) always in the hundreds, very stable, and the system was ice cool!
Not so much with Odyssey. (for me)
Crash crash crash crash....when in SLI mode, or alternate frame render mode.
I've had to devote one card exclusively to Odyssey - and the other just runs background Windows stuff...
Performance isn't amazing - heat is through the roof - but it's playable atleast
Reading the experiences of other SLI users with Elite however....It seems practically random how your specific system will react with Odyssey!
I wouldn't expect Odyssey to do well with SLI, especially on GTX 970s. The cards don't have enough VRAM for a good Odyssey experience at higher settings, and the game's highly bursty and erratic CPU utilization means the cards aren't going to be the limiting factor as often as not.
I ran crossfire R9 290Xes in ED for a while, worked alright, but frametime inconsistency did mean effective scaling was only about half of what it should be. Still, rarely had issues making it work.
Fire is one of the only purely GPU limited areas of Odyssey at middling (1440p) resolution for me. They did slightly improve it's performance, but it looks comical. Most of the bloom is gone, the flame animation has been thinned out, and the render/update framerate of the flames is low. Since my cards could handle the old fire, this is a decided downgrade for me.
Not done transcoding yet, but you'll get the idea (~five minutes in):

I went from 62 fps minimum to 64 fps minimum between old an new fire in the tutorial, 1440p ultra.

Doesn't look like I'm getting much of any FPS gain in Odyssey with SLI enabled from disabled. I'm using the current game and driver versions. With SLI enabled both GPUs are being loaded, but not resulting in any significant FPS boost that I can tell, unlike Horizons where I'll see maybe a 50% or so FPS boost with SLI.
So... I guess one more reason to stick with Horizons for the time being, beyond occasionally testing a few things here and there.

SLI is NOT working in EDO. Please add your report here: https://issues.frontierstore.net/issue-detail/32304
We should be able to get the confirmation threshold on this one.

Same setup I used to have - weird, mine was super awesome 200FPS stuff one day, literally the next day without doing anything, it'd rock between 120 and 80FPS, sometimes dropping below 60 for a bit.
This was always after driver updates, or, elite dangerous game updates, either one seemed to screw it.
You sure? How did you get it working? That was the set-up I had, but it never worked with E: D. I got rid of one of the cards as the only game I found that did actually use SLI was NVidia's Circus game demo. E: D has never supported SLI, and if the game doesn't support it, it shouldn't be possible to get the cards to work together...
NVIDIA's drivers had an SLI profile for ED, and even without one specifically targeting a game, it's usually possible to get some degree of functionality by setting custom SLI flags. Most DX11 and earlier games can be made to work with AFR to some degree.
I wish I'd found this information while I had the second card. Do you have any references (I did spend a lot of time looking into this at the time, and didn't find anything like this - it's possible I was drunk, I suppose...)?
I just checked one of my NVIDIA setups with fairly recent drivers. SLI profile for ED is still present (anything with an SLI specific hack with it's name on it definitely has a profile in the drivers):
In general, most games could work with some functionality simply by setting "AFR compatible" in the SLI options in the driver control panel, and the number of games that wouldn't work at all with SLI after tweaking compatibility bits in NVIDIA Profile Inspector was pretty small.
Elite: Dangerous had some severe scaling issues with SLI on some drivers, but plenty of people got it working.
As I had mentioned, the stock driver SLI profile for Elite: Dangerous works great for me still in Horizons on my Titan Black cards. I'm seeing roughly a 50% FPS gain, no tweaking nor custom profile made.
Odyssey though, I'm not really seeing any FPS gains from SLI, which might help explain its exceptionally poor performance on my system compared to Horizons, getting only about 1/3 the FPS.

Happy to report that SLI in Odyssey is now giving me a performance increase in FPS of 40% or so in the hanger, compared to having it disabled.
Performance is still quite low compared to Horizons at roughly half the FPS. Better than the third I was getting before at least.
Cheers.

I wouldn't recommend it. Newest cards don't support SLI.
