NVidia DLDSR (Dynamic Super Res+AI) Examples/Thoughts

[smogsy]

thought it would be cool to discuss DLDSR experiences here in 1 thread
All my images will be DSR 1.78x from 4K (5461x2880)

What are these?
DLSS - takes a render image resolution (say 4k) Then renders at a % of that resolution & upscales. DLSS Balanced would rendering at 1080 & upscaling to 4k - Qaulity would be 1440p -> 4K

DSR - does the oppssirte renders at % higher & scales down the image for better visuals
DLDSR Does DSR but uses AI/Tensor cores for calculations to make the image better with less fps impact

Snowrunner - works flawlessly no FPS drop (maybe 4fps max)
God of war - Does not detect higher res (maybe due to borderless only)



Snowrunner

so far ill be using it in all games i can

 

[smogsy]

all games tested 4fps drop if that

I haven't noticed any difference, as if it's turned off....... Yes it's turned on correctly in the Control Panel.

Didn't do anything in Battlefield 2042 for example

You did set your resolution to your new resolution in game right?

4k will be 5xxx x 2x

From what I've seen, the steps are.

1. Go to the NVIDIA Control Panel, under 3D Settings > Manage 3D settings > DSR - Factors. This is set globally, not per game.
2. Choose between 1.78x or 2.25x.
3. After applying the change, you should not have access to a higher resolution option on the desktop and in game e.g. on a 1440p screen, using 2.25x, I now have access to 4K (3840 x 2160).
4. You don't need to change your desktop resolution, just the game.
5. Open the game and set it to the new resolution.
6. Seems to work fine with DLSS.

I tried it out with Shadow of the Tomb Raider. Using the in-game benchmark.

• 1440p Native - 109 FPS
• 1440p DLSS Quality - 140 FPS
• 4K DLDSR - 58 FPS
• 4K DLDSR + DLSS Quality - 85 FPS

The last config would be my pick.

your last one is a weird combo but cool. but your intstructions are correct

so to break this down for 4K (now 5xxx due to dldsr)

DLSS your Saying render at 1080p/1440p & upscale to 4K
DLDSR then at the same time render at 5K and downscale to 4k..

my guess is it renders at 5K then DLSS uses 5K as % so use arounnd 1600p (% of 5k) hence you get 85fps

so DLSS qaulity would be around 1600/1800p

 

[smogsy]

Well since you're telling the game engine to render at 4K, DLSS should be working from the 4K image, and not the DLDSR 1440p image.

I have no idea what the actual order of events are. The combo of DLSS and DLDSR worked flawlessly for me - gameplay was smooth.

so worked it out

DLSDSR would be set at 5K (4k+DSR) (so game is rendering at 5k)
So DLSS would use % of that 5K image (1600p-1800p) to do its calculations (4K is 1440p)
so your using around 2890x1600p as your basis for all DLSS calcuations

Sorry to be the thick turd and ask this question.
DLDSR? What is this/ How does this differ to the infamous DLSS?

DLSS - takes a render image resolution (say 4k) Then renders at a % of that resolution & upscales. DLSS Balanced would rendering at 1080 & upscaling to 4k - Qaulity would be 1440p -> 4K
DSR - does the oppssirte renders at % higher & scales down the image for better visuals

DLDSR DOes DSR but uses AI/Tensor cores to make the image better with less fps impact

 

[smogsy]

updated orignal posat with these answers for all

 

[smogsy]

So if I am using a 1440p monitor, what would I be aiming to do?

Not really looked into this all that much but sounds interesting.

well
Game that has DLSS

you could use DLSS to take calculation from 900/1080p and upscale it 1440p (better FPS) than native 1440p little sharper picture

Game without DLSS
you could use DLDSR to render your game at 4K then downscale the picture to 1440p (less fps than above but better picture)


Game with DLSS & Have perf left on your GPU
You could use DLSR+DLSS to render at 4K & use then use DLSS Calculate your DLSS image from 4k render (1440p at Qaulity dlss) to give you a smoother/sharper picture with slighty less fps than native 1440p

 

[smogsy]

In theory what this allows is getting the same image quality increase from DSR as before but from rendering a lower amount above your native res which results in less of a performance hit.

just uses AI and tensor cores to reduce perf hit

 

[smogsy]

does 'OFF' setting give best fps, or any tweaks?

Off is off standard nvidia rendering

 

[smogsy]

So how do you turn on the DLDSR in older games ? Is it simple just switching on the DSR?
But that was there from before though?

1. Go to the NVIDIA Control Panel, under 3D Settings > Manage 3D settings > DSR - Factors. This is set globally, not per game.
2. Choose between 1.78x or 2.25x. (notice old dsr is called legacy)
   
3. After applying the change, you should not have access to a higher resolution option on the desktop and in game e.g. on a 1440p screen, using 2.25x, I now have access to 4K (3840 x 2160).
4. You don't need to change your desktop resolution, just the game.
5. Open the game and set it to the new resolution.
6. Seems to work fine with DLSS.
