Watch On As commenters online have noted, the method seems more akin to using Nvidia's dedicated PhysX cards, with plenty of potential for gamers who have the capacity to run a dual GPU setup. The second demo features a Ryzen 5 5600 on a DDR4 system, so top-of-the-line hardware isn't required to make it happen.

usertests It's a recreation of the original demo of DLSS 5, that ran on two RTX 5090s. Reply
Jabberwocky79 Ah yes, I remember running dual GPUs while offloading PhysX to one of them. Eventually I was able to up my rizz to a GTX690 which was a dual-GPU card all in one. This could actually be practical for the bleeding-edgers who want to run DLSS5 right now. What I'm curious about is the performance gains to be had when one card is inferior to the other. Like, what's the budget/performance sweet spot? A 5080 for raster and a 5050 for DLSS5? Or…..? Reply
PEnns "…a 32GB DDR5 setup with two Nvidia RTX 5060 Ti 16GB GPUs, with both cards using PCIe 5.0 x8, and a display attached to each card." Just throw enough GPUs, RAM and monitors at the beast and it will be tamed in no time at all. What's next in that magician's hat? Quantum Computing to grab the holy grail of DLSS at any cost? Reply
Vicecrow I'am using the INTEL UHD 770 to display what the RTX 5070 can provide. can output 2560×1440 at 120hz without issue. on quake 2 rtx with dlss 5.0 got 100-90 fps. maybe a free Gpu card to output the video will free the acellerator and gave good amount of free fps. Reply
Vicecrow Tried now with the OLD game THE ASCENT only rtx 5070 220 FPS 1920×1080 ultra with dlss5 90 FPS Using the intel UHD770 for display got 197 FPS and 87 FPS with DLSS 5 Loose performance 3 fps The RTX 5070 has locked 170w max at this test dlss 5 172w max without 130w Reply

I used a PCIe x1 GT 730 for PhysX when using SLI 780tis. Then the W3 stopped using hardware PhysX 🙁 Reply
blppt The thing that always bothered me about the death of multi-GPU gaming was that DX12 was supposed to help make it easier to put games together that wouldn't require the overhead of the patchwork AFR technologies from Nvidia and AMD. Instead, the tech just disappeared. Not that most people can afford two high end 5-series cards anyways…. Reply
usertests blppt said: Instead, the tech just disappeared. Not that most people can afford two high end 5-series cards anyways…. We keep seeing opportunities to pair two GPUs together, or even GPU + iGPU. PhysX (before Nvidia unkilled it), Lossless Scaling, DLSS 5… Reply
