Multi gpu support?

[bgray9054]

@ CDPR / Moderation

Can you advise on what API the game is being made in and if it will have multi gpu support? Thanks very much.

I have tried a sli setup many times and no matter what kind of framerates i got in-game(why use a benchmark)it always performed equally or often better to a brand spanking new card that cost twice as much. Despite the ignorance of some people here you should never underestimate the power of greed and what it can make people do, such as removing sli from gaming to force us to buy these heavily overpriced new cards.

no need to spam comments like sli is dead etc, really. please , dont,
people here r lookin for solution and dev's respond.
current gpus as 3090 and ,most likely, future 3080ti HAVE sli feature.
nvidia Still offers Sli solutions so it means sli is alive. if next gen gonna loose sli feature then i say sli is dead.
some gamers invested huge amount of money to recieve best experience on cyberpunk. 4k resolution and 30-40 fps on single 3090 with Ultra + RTX Ultra + DLSS Quality? i wont be happy .
no i dont have 3090 , am using two 2080s. and game 's perfomance kinda bad.

Ya, I've run about 5 multi gpu setups over the last 10-12 years and had really great experiences with all of them. I've just recently sold my 1080 Ti SLI setup and bought a used 2080 Ti for about half its original MSRP - you're correct on what NVidia is doing with the overpriced cards now - that's why I stopped buying them new. I'll likely continue running one or two generations behind moving forward and just buying via 2nd or 3rd hand market as I simply will not normalize the pricing of these newer cards by purchasing them new. Over $1k for a single video card? lol...no. And I have tons of $, but that's just ridiculous.

The lack of SLI support is really disappointing, I wanted this game but now I think I'll refrain from buying it. In fact, it turns out that only owners of solutions of the level of GTX 3080 or higher can get the full experience of the game. I am very disappointed.

Same here, I was really hoping that SLI will be supported with this game but sadly is not. Won't buy it for now. I'm tired with all theses games not SLI friendly.

Multi gpu not work ;((( https://ibb.co/hD17D5B

I love all the people popping in here to say that SLI is dead. Full disclosure - my last SLI rig was two 1080 Tis that I replaced with one 3090.

With that said, here's some knowledge for some folks:

SLI is DX9 through DX11 only. It's implemented through Nvidia drivers and the game devs. Yes, sometimes you can skirt around this by using SLI profiles from other games.

MGPU, explicit or implicit, is what DX12 uses for multiple graphics cards. It's implemented through the game devs only within their game code with no driver side requirement (e.g. SLI profiles).

Cyberpunk 2077 is DX12 only. Therefor, SLI doesn't even apply - it's MGPU only.

So, if you're gonna bad mouth multi card setups, do everyone a favor and at least bad mouth the correct version, and bad mouth CDPR for not putting in a little extra effort that even smaller game developers have.

^ Well-said. I liked how well-implemented mGPU support was with the Tomb Raider games as an example. 4k / 60fps without a hitch on a pair of 1080 Ti cards.

The TR team at Crystal Dynamics show what can be done with mGPU support. I second your opinion. Did it require a bit of extra effort to implement? Yes, but their solution for DX12 mGPU was before they even added full RT support. They continued to support mgpu on DX12 and the RT features worked just fine. It looks gorgeous and the framerate is buttery smooth running 2 1080tis in my old rig and current rig with 2 2080tis. Squeaky wheel gets the oil so keep these mgpu threads alive folks. CDPR had great dx11 SLI support for The Witcher 3 and it is a sight to behold maxed out on a 4k HDR display six years later. I can see Nvidia not wanting them to do mgpu day 1 to keep 30 series demand high (as if scalpers/bots buying their inventory in seconds isn't enough) but a 3090 not hitting 60fps currently is all the more reason for mgpu. As they further patch and optimize this game I really hope this is on their post-launch project timeline for 2077. DLSS does return some performance but it isn't exactly wolfenstein youngblood in terms of a equal or better solution than native res but the only option currently if you want playable framerates and the RT eye candy.

The Witcher 3 sold 50+ million units not only by being one of the best action adventure RPGs ever made but by the constant TLC and updates over the years. Let's hope THAT CDPR lives on and we can all toss a coin to a de'V'. Hell I bought the fugly but fully playable switch version (the visuals grow on you after the initial shock and you realize despite the low res and aliasing a lot of the visual features ie fully dynamic trees, weather etc are in there) but I bought it because these maniacs did Switch/PC crossave!

TLDR-CDPR has a great track record with post-launch support. Let's let them know mgpu is at the top of our wish list.

ok so this is just for your own good, sli is being dropped from most if not all titles curently no one wants top deal with it anymore and no one will, io think the 3090 has sli support but no games will be utilizing it anymore along with crossfire, i wouldnt hold my breath, if you do you will die


at best sli and xfire are just used for benching

This is a thread requesting it, we already have six pages of people saying this sh!t. If we own multiple GPUs, we know the official support status, but also the many custom inspector nip files for SLI/mgpu. We don't need this "SLI is dead" s#$t every other post. Thanks.

snip - for length

Yep, my thoughts exactly particularly with what you said about the 3090 - $1500+ GPU that can't reliably run this game at 4k / 60fps...utterly pathetic. It's a very clear statement of why mGPU should be pretty darn mandatory on any graphically demanding AAA title. I refuse to play into NVidia's little game where they are trying to sell these video cards for what, just a few years ago, was the price of TWO high end video cards, lol, and we don't even get the performance equivalent. I'll likely be buying my video cards 2nd hand or even 3rd hand moving forward.

Probably not. Multi-GPU is dying, mostly intentional - NVIDEA and AMD dont want people saving money by buying two cheaper cards rather than one crazy priced new card. Its the very definition of bad business plan.

Very few games support the multi-gpu scaling necessary to actually use the second card. As far as I remember there have only been a few AAA games in the last couple years to actually do GPU scaling for this.

So Im going to predict that it wont. Its a relatively small crowd to cater to, as per steam hardware surveys very few people use multi-gpu's.

Incorrect, SLI/Crossfire is dying, DX 12 and Vulkan support Multi-GPU via their API's this means coders will no longer have to rely on support from GPU drivers and can choose to support Multi-GPU in software.

For a good example just look at Ashes of the Singularity: Escalation. DX12 Multi-GPU support works wonderfully in that game and actually uses BOTH adapter's VRAM instead of just the primary adapter's. So if you have 2 8GB GPU's install you have a total of 16GB addressable instead of just 8GB.

SLI/Crossfire = Old way
DX12/Vulkan Multi GPU = New way

[AstralStorm]

Of course CDP Red did not implement any support for mGPU. The game was already rushed maximally so they did not even think about it.

This will be the story with all DX12 titles as mGPU there takes a plenty of additional work. Likewise Vulkan (though slightly less work).

And current top GPUs cannot even touch the amount of raytracing this game attempts to throw at them, RTX or not. (DLSS and the like is fake resolution.)

[Suburban_Seven]

This game needs Multi GPU most of all, as hard as it is to run on everything
