Hi all!
Anyone heard and rumors of VR-SLI support? Note that this is NOT standard SLI, but a special API that uses one GPU per eye, not the alternate (in time) frame rendering that normal SLI uses to increase FPS. Info here:
https://developer.nvidia.com/vrworks/graphics/vrsli
1.7x improvement in frame rate could be a game changer.
Cheers
I will never trust Nvidia again with such technology as it’s been a failure ever since dual 8800 GTs.
They can keep renaming the tech all they want…SLI…NV Link…VR-SLI.
Nope never again.
I’ve been a SLI guy from day one, with the voodoo cards. I will never ever under any circumstances ever apply, use or otherwise even think about SLI/NVlink ever again… At $2500.00 bucks per card solidifies it. I think Nvidia should be investigated for price fixing/gouging.
SLI Never.

Yikes! More of a theoretical proposition than a financially good idea. The graphics loads are just so far ahead of the GPUs in VR, I’m trying to see any path towards 90 fps in a Pimax 8KX that doesn’t require teleporting into the future.
I think foveated rendering will have to come to the rescue.
Haven’t they been talking about this for years?
I know I heard of “separate GPU per eye” since at least the Rift DK2 days. Nobody has managed to try it or pull it off yet.
Not technically true… there are a few examples. Take a look at the talos principle for example (or actually pretty much any croteam game).
That said it clearly never took off, much like SLI in general.
With the current state of SLI I don’t see it happening. SLI is all but dead… you can’t even do it on the 3000 series apart from the 3090.
Yeah if you read the link from my post, apparently a handful of games supported it and they say 1.7x increase in FPS during testing (by NVIDIA i think).
Although 1.7x would take 25 FPS to 42.5 and feel awesome, where you want to be, high settings on a Pimax 8KX would be taking 0.5 FPS to 0.85 FPS and not so much…
Is it because they don’t wan’t people buying the newest cards rather than using two older/cheaper cards together?
good point! 1.7x faster is not all that much more than you get with each generation of cards…
Perhaps that’s part of it, and cards are more expensive these days so the potential market for people buying two of a new card is even smaller than it was before.
I believe mostly the problem is it’s on the developers to put in the effort to get it to work properly and most developers aren’t interested in putting in the required effort for such a small subset of their market… so developers largely didn’t bother, as a result even fewer bothered getting SLI as most games don’t benefit much, and thus it ultimately becomes a self fulfilling prophecy.
I had 2x 980Ti back in 2015ish and it was really such a waste of money in the end. Haven’t bothered with it since and now like I say it’s not really even a realistic option on Ampere. Next big frontier is MCM GPUs anyway!
I had 2x 9800s back in 2009, Crysis 1 laughed and choked them both out​:rofl:
Looks promising; just put another 3090 to order.
