A developer has vibe-coded a brand new ReShade add-on file that offloads the DLSS Neural Rendering workloads to a second GPU, nearly negating the in any other case huge DLSS NR efficiency hit. Given the unique DLSS 5 photographs we noticed when Jen-Hsun first confirmed off the characteristic round GDC and GTC within the Spring had been working on two graphics playing cards, that is not wholly shocking, however this mod definitely does open the the potential for conserving your outdated GPU round for neural coprocessing sooner or later.
Like nearly the entire present DLSS 5/Neural Rendering implementations we have seen the place the person will get to select the sport, the mannequin, and the burden of the consequences, the Neural Coprocessor add-on file—mgpu_bridge—is designed for ReShade, an app used to inject totally different visible results into PC video games. The information exist on Github, could be downloaded and added right into a sport that is already been modded with DLSS 5 assist, and will dramatically enhance the efficiency.
That is, for me, the largest challenge with each the homebrew mods for DLSS Neural Rendering and the one launch implementation we have seen from Nvidia and the builders themselves: the hefty efficiency penalty from turning it on.

Nvidia itself has touted a 50 – 60% frame rate hit as a blanket determine—no matter sport and the way a lot AI filtering it is doing—as what it’s anticipating to see from enabling DLSS NR. Andy benchmarked NBA 2K27 forward of launch and located that typically the body price affect could be even larger than that.
I imply, it is not as dangerous as if you try to run DLSS NR on AMD GPUs, however I’ve famous these sorts of efficiency hits if you run the brand new characteristic via ReShade, too. However Marcelo Guibout has coded a ReShade add-on file that enables a second GPU—right here an RTX 5060 Ti 16 GB—to take the ultimate completed body and carry out the neural rendering move on that GPU and output by itself monitor. Meaning it does not have handy the body again, which provides its personal efficiency hit and latency.
They initially used a neighborhood mannequin—Qwen3.8-27B-Q6_K—working on LM Studio utilizing the identical pair of RTX 5060 Ti 16 GB playing cards they ultimately examined the characteristic on. This created the “preliminary add-on scaffold” which they then took into Claude to put in writing many of the C++ core, although Anthropic’s AI “additionally produced a number of assured, well-formatted, incorrect diagnoses alongside the best way.”
Trying via the Github documentation Guibout makes it clear this isn’t a production-ready add-on, and is generally offered for additional analysis and improvement. They be aware it has been run on precisely one machine with three video games, and encourage everybody to learn the supply code earlier than working the information. However it’s nonetheless a extremely fascinating improvement within the DLSS 5 modding story.
“The rationale it’s value doing: neural post-processing saturates no matter machine it runs on,” writes Guibout. “Run it on the render GPU and decreasing your render decision simply frees capability the neural stage instantly eats, so upscaling stops paying for itself. Transfer it to a second GPU and the render GPU is genuinely freed.”
DLSS NR on AMD
AMD GPUs working DLSS 5 appears nice, however runs horribly.
That is nearly definitely the rationale behind Nvidia initially working the characteristic on two GPUs for the unique demos, and the truth that it can get it working on a single GPU continues to be spectacular from a technical perspective, however having a coprocessor dealing with the load ought to provide the better of each worlds.
Although there are apparent caveats to this.
The primary being that it is costly sufficient to purchase one graphics card proper now. You have a look at this mod and the very fact it has been created and examined on a pair of RTX 5060 Ti playing cards and suppose that is kinda mid-range. They’re the fifth-tier playing cards of Nvidia’s RTX Blackwell stack. However these are two GPUs that now price one thing round $800 apiece, so we’re nonetheless speaking about needing $1,600 value of graphics silicon to get this working.
The opposite caveat is that we’re working on with two displays right here as a necessity. Guibout notes within the Github readme file that, “The second monitor is a requirement, not a nicety – the neural output is displayed by the cardboard that produced it. Headless works and is meaningfully slower.”
The third caveat right here is that this ReShade implementation is a remaining step course of. It’s dealt with after the ultimate body has been rendered and works with not one of the depth and movement vector info the official Nvidia implementation runs with. Meaning the second-GPU goes to need to be extra tightly built-in into the precise rendering course of. Not fairly as tightly sure as with SLI, maybe, however it would absolutely nonetheless must get entangled earlier than the ultimate post-processing is finished.
However I might doubtlessly see this as a solution to do one thing helpful along with your current-gen card if you subsequent improve. And, on a purely mercenary stage, it may be a wise factor for Nvidia to really make as a characteristic as it will have the impact of locking somebody into the GeForce ecosystem much more securely.
Although instances have modified and SLI and CrossFire have died, and so motherboards are even much less seemingly at present to have a number of PCIe x16 sockets accessible to stay secondary GPUs into. Particularly in case you’ve acquired a number of NVMe SSDs taking on treasured PCIe lanes.
I am loving the speed of improvement occurring outdoors of Nvidia now that the characteristic has fallen into the arms of the group at giant. And no matter how you’re feeling concerning the expertise, I might encourage you, you probably have the {hardware}, to try how even simply the ReShade implementation appears, and how one can alter it. It provides an enchanting perception into the expertise, into its limitations in addition to its unwelcome excesses.
Although it is not all the time simple. I’ve spent the morning making an attempt to get this ReShade add-on working with the take a look at rig, as a result of I used to be to see if it might be run asymmetrically, as I haven’t got a pair of RTX 5060 Ti 16 GB playing cards. Sadly, with an RTX 5080 and RTX 5060 Ti because the neural coprocessor, I couldn’t get the add-on to arm when in Cyberpunk 2077. So, I’ve acquired extra work to do to get this factor working.
