You can try the optiscaler implementation: https://github.com/Dagherbou/OptiScaler_DLSSNR/releases/tag/v0.1.1.5-dlssnr
It let's you change the NR resolution from 100% to 75%, 50% and 33%
But it drastically decreases the fidelity of the NR, imho it's already a heavy but usable impact at 75%, then becomes virtually useless below, even though it also runs way better.
I think the problem with the current implementations is that they can only run on the final frame
But the ideal way would be to run it together with something like DLSS, lets say render a 4k output at 1080p or so, apply the NR to that image, and then let DLSS do it's upscaling magic
That should dramatically improve performance while only marginally decreasing fidelity
Pretty sure that is how nvidia intended it, but obviously requires proper game implementation or a more in-depth game specific mod like PureDarks Skyrim upscaler

DLSS 5 launches on September 3 with NBA 2K27, gonna be interesting to see what the actual benchmark results are instead of how its implemented as a mod and with the pre-release version (though its of course possible nothing has changed).

No way, its a 23 year old game so a 50% or more drop in FPS is nothing if you get like 400 FPS or whatever, which would pretty reasonable for such an old game as CoD. not sure what you mean with more passes, its with DLSS 5 on and off, not dual DLSS 5..
I have a hard time thinking the performance drop can be this much for actual DLSS 5 when its implemented for games. it would appeal to less than 1% of gamers (5090 users are 0.4% of Steam users), so its practically for no one, or its something for next generation of cards and to hype those up. We'll see.
Edit: talked a little to chapgpt and this is what it predicts in terms of performance
Most likely: 5070 Ti works quite well at 1440p, perhaps with a noticeable ~15β30% neural-rendering cost. DLSS SR + FG compensates for it. RTX 5090 gets the spectacular 4K showcase numbers.
Less pleasant: 5070 Ti works, but DLSS 5 is expensive enough that you really need aggressive upscaling + FG/MFG. NVIDIA can truthfully advertise support, while RTX 60 later gets much faster neural inference.
Worst case: current Blackwell is effectively a preview platform and DLSS 5 only becomes genuinely attractive on RTX 60. I think this is possible, but less likely.

@Amadeus Haha no chance with a 4090

That 50% number is only a relative estimate for modern games
Of course the compute cost of something like DLSS 5 is many magnitudes larger than rendering a 23 year old game on a modern GPU, which will hit engine, driver and CPU limits first
So rather than going from 400 fps to 200 fps you're going to maybe 50-60 fps
There really is a limit on how many NR frames of a given resolution a RTX gpu can output
For example Deus Ex runs at like 600 fps but with NR only runs at around 70 fps, that's on a 5080
Because while the GPU can output many more rasterized frames than that, it can't produce more NR frames than that
PureDark managed to implement a way to select a different GPU for framegen and NR
So he let his 5090 run the raster on Skyrim
And a 4070ti running DLSS 5 / NR
It managed to do around 30fps
But I am sure official implementations will run better, esp. since they will likely run NR on frames before upscaling, so at a lower resolution
That Call of duty (2003) screenshot definitely ran multiple passes of DLSS 5 thanks to special mods that let you run it up to 10 times on each frame, which ofc will result in more extreme results, more artifacts and far less performance.

Pretty cool though, that you can run it that way. But in this specific case wouldn't it be better to use the 5090 for the DLSS 5 part? Surely that would result in more FPS?

i checked and you're right, it was a 3x pass. still, really impressive result.. looking forward to test it.

It depends on the game (enigine) a lot.

Yeah, that looks awesome.

It's how it looks and performs modded with a pre-release... how its applied in an official pipeline might be different.
Trails in the Sky looks like several layers of it btw, someone did it to make some stupid point and to get viral for the anti-AI bros.

That's more akin to Ageia PhysX coprocessor than SLI.

I was surprised Nvidia were not trying to flog a second GPU for ray tracing.
No more multi GPU for me. Not with today electricity prices.
