Huge framerate increase thanks to Nvidia DLDSR

o7 CMDRS

I take advantage of having recently updated my PC with the latest Nvidia drivers to make a short tutorial, which allows to significantly increase the game performance.

We're speaking about a performance increase up to 30% in stations, and 40% on planets for CMDRs playing in 1080p.

You may know it, but Nvidia has recently released a new technology: the DLDSR. It's a technology that is only compatible with RTX cards, and that is available with the last update of January 22nd.

The idea is simple: it is the opposite of DLSS. The game starts from a higher resolution and then goes back to a lower resolution.

Basically, you need to go to the Nvidia graphics options, and go here:

https://www.noelshack.com/2022-06-7-1644757451-image.png

There, you go in "DSR - Factors", and you mark the following fields (1.78x, 2.25x)

Once this is done, you apply the changes in the bottom right corner.

After that, you launch the game, and you change the resolution to a higher resolution (for example, in my case I was in 1080p and I changed it to 1440p). Now you're going to say that it's a basic hyper-resolution like it's been existing for 5-10 years, but no! The impact on performance is quite negligible (I went from 100 fps to 85-90 fps, where I clearly should have been around the 50-60 fps with a change to native 1440p).

And once that's done, your game will be much thinner with less aliasing (kinda abvious as you've increased your resolution)! You can then switch your oversampling to x1.0 instead of x2.0. The game will still look pretty good or even a bit better. And since you have reduced the oversampling, tadaaa! You went from 100 to 140 fps, with the same image quality!

Here are some screenshots I took to give you an idea:

Native 1920*1080, FSR FidelityFX, oversampling 2.0, 90 fps: https://www.noelshack.com/2022-06-7-1644759248-19201080-2x0-95fps.jpg

Upscaled DLDSR 2880x1620, FSR FidelityFX, oversampling 1.0, 130 fps: https://www.noelshack.com/2022-06-7-1644759263-2880x1620-1x0-130fps.jpg

Upscaled DLDSR 3840*2160, FSR FidelityFX, oversampling 0.75, 135 fps: https://www.noelshack.com/2022-06-7-1644759298-3840x2160-x0-75-130fps.jpg

I also calculated the difference in performance between 1080p, 1440p and 4k, all four at x1.0 oversampling, and it clearly shows better performance than if you go for a basic hyper-resolution:

- 1080p: 185 fps
- 1440p: 160 fps
- 4k: 85 fps

1440p is almost two times heavier than 1080p, and 4k is four times heavier than 1080p. So the results should be something like this with a native hyper-resolution change:

- 1080p: 185 fps
- 1440p: 100 fps
- 4k: 50 fps

And here are the results I have in Jameson:

Native 1920*1080, FSR FidelityFX, oversampling 2.0, 60 fps: https://www.noelshack.com/2022-06-7-1644769573-19201080.jpg

Upscaled DLDSR 2880x1620, FSR FidelityFX, oversampling 1.0, 80 fps: https://www.noelshack.com/2022-06-7-1644769588-28801620.jpg

Upscaled DLDSR 3840*2160, FSR FidelityFX, oversampling 0.75, 80 fps: https://www.noelshack.com/2022-06-7-1644769604-38402160.jpg

I may not have understood everything about this new tech yet so if some people want to complete/correct me don't hesitate ! :)

Also, here is my RIG:

Motherboard: Asus ROG Strix X570-F
CPU: Ryzen 7 3700X @ 4.3 Ghz
GPU : Gigabyte RTX 3070Ti 8Go
Memory : Corsair Vengeance RGB Pro 32Go (4x8Go) DDR4 3600MHz
SSD M2 Kingston MVMe 1To

Jeebus man, with that graphics card you should be getting good performance anyway. Its way more powerful than my 2060.

Admittedly, i only run at 1080p, which is my monitor's native resolution anyway.

Supersampling shouldn't have been above 1 anyway if you were having performance issues.

In fact that's probably WHY you were having performance issues...

Well, 1080p with FSR FidelityFX x1.0 looks like ♥♥♥♥♥. Aliasing is absolutely awful, and putting it to x2.0 was the only way to get a decent result :/

But here, thanks to DLDSR, I can put it to 2880*1620 (which means aliasing is less important), keep it to x1.0, have a similar rendering but 30/40% extra perf

Agree, but the game has such a crappy optimization that a 3070Ti is not overkill at all for EDO.

In the meantime, can run Crysis Remastered in ultra 1440p at 80 fps...

DSR is not DLDSR.

DL stands for Deep Learning DSR.
As far as i know DLDSR and DLSS only available from DX12+ and elite is DX11.

You gain better performance and/or quality with normal DSR already, but with Nvidia Deep Learning you should see even better results.

Mmmmmh since I've been able to apply DLDSR resolutions to very old games (Morrowind, Oblivion, Crysis, etc.) I guess it shouldn't be related to DX version ?

Not sure of it tbh, and I don't really know if this new resolution brings the DLDSR technology with it on these old games. Maybe it just considers it as a simple hyper-resolution upscale ?

But I also submitted this technique on a french-speaking discussions board, and the people who tried this told me they had noted a significantly framerate increase on EDO.

DSR should work with any game. it is downscaling technique. It basically renders at higher resolution and then downscales it to your monitor resolution. This makes the image look sharper, but it actually costs performance. It should only be used if you actually have some GPU overhead.

Now DLDSR is an upgrade to this, making the downscaling slightly more efficient. You get better results in terms of quality and performance compared to regular DSR.

DSR in general is improving quality at cost of performance. If you get better performance with DSR activated its likely something else that is slowing it down when DSR is off. Check the "Supersampling" setting in the game. Possibly when you have DSR activated it turns off supersampling in the games settings, that what gives you the performance gain I guess.

Now in terms of performance gain more interesting is DLSS (Deep Learning Super Sampling).
This is just the opposite, an upscaling technique. It renders at lower resolution and then upscaling the image and inserting pixels using deep learning AI. This can boost performance significantly without losing much of quality. So you can render something at 2K and upscale to 4K. It renders as fast as 2K but looks as sharp and clear as rendered in 4K. Also it replaces anti aliasing techniques saving even more performance and the quality is better then with 8xMSAA.

But DLSS works only in games that support it and only with DX12.
Mount and Balde Bannerlord in example supports it. When you activate it, you can crank up the resolution up to 4k and you still gain up to 50% more fps compared to 2K without DLSS.
