Mod Demonstrates Multi-GPU Setup for Dedicated DLSS 5 Processing
A YouTube mod by Marcelo Guibout uses a secondary GPU to handle DLSS 5 upscaling, showing notable frame-rate gains but raising questions about driver support and market impact.
YouTuber and modder Marcelo Guibout posted a demonstration in which a dedicated graphics card runs DLSS 5 processing while a primary GPU handles the main rendering workload. The configuration reportedly delivers higher frame rates compared with using a single card for both tasks. Guibout’s video has sparked discussion among gamers about the potential revival of multi-GPU setups for specific functions such as AI-based upscaling and motion-fixed-gaming (MFG).
"It’s good to see there are avenues for performance gains, but also sad to see that the shortage of GPU supply will increase if Nvidia officially supports this," wrote one commenter.
"Will Nvidia lock it like PhysX? This could be the solution for many and a way to promote DLSS 5 faster," another user asked.
Enthusiasts noted that the approach resembles older SLI and PhysX configurations, where a secondary card accelerated particular workloads. Some participants suggested that similar schemes could work with mismatched GPUs or even across brands, though others warned that driver restrictions and added latency might limit practical use.
Industry observers cautioned that, while the mod showcases a novel use of existing hardware, it remains unofficial and could be vulnerable to future driver updates that block such functionality. The discussion also highlighted concerns that an official endorsement might exacerbate the current GPU supply shortage.
