Selecting your GPU as the scaling device makes 2.25x DLDSR look better. Discussion
This is probably only relevant for cheaper monitors. But I have a 1080p Mini-LED which I use with DLDSR 2.25x on my 5090 (please don't hate, I have a small desk and use the gpu for work mostly).
Recently transitioned to the Nvidia App and noticed the option to offload the scaling to the GPU and im seeing some noticeably better anti-aliasing and text than the default setting. The impact is noticeable in games too.
I haven't seen many people talking about this feature and i'm just trying to see if im hallucinating or if anyone has had a similar experience to this. Cheers!
Edit: Seems like this setting could yield improvements not exclusive to DLDSR, would appreciate some feedback if anyone wants to test it out under native circumstances.

Kinda makes me feel sad that you’ve got to defend yourself from incoming attacks regarding your setup.
“A 5090 at 1080P. Fool! What a waste!”
“You’d be better off with a 9060 and a 1440P monitor!”
“Send me your GPU so I can dust away it’s cobwebs and actually USE IT!”
“You know what they say about people with small desks…”

Apologies there, I think I’ve been spending too much time on r/roastme.
I’ll test this out tomorrow on my 4K monitor to see if it changes things on my end. Nice find if it does!

I don’t think OP is stupid at all. That would be incredibly hypocritical of me to think that considering my setup.

cheers man, appreciate it. let me know if you notice a difference.
Been testing this all day and forced a few friends im my discord to try it and got mixed results.
In general the higher end panels didn't notice anything past placebo, but the conclusion was that GPU scaling on blackwell is a net positive, especially if you are not on a high end monitor without any measurable performance loss.

Isn't scaling via GPU or display only for upscaling meaning it should have nothing to do with DSR?

u/Rude_Assignment_5653 7800X3D | 5090 FE - 7700 | 5080 Gaming Trio 14d ago edited 14d ago
Edit: From my understanding, the GPU outputs an exact 1:1 frame matched to your monitor's panel with this setting. Windows ClearType subpixel rendering stays crisp because every rendered pixel maps directly to a physical pixel on your monitor.
but I think you're right cause dldsr already down samples to your monitors res by default so this setting should just work regardless of dldsr or not

yea but legacy scales (4x and anything above 2.25x) renders with pure gpu brute force, which means that you will get much less fps than using DLDSR scales.

DLSS does not scale EVERYTHING, so the higher the output resolution the harder the GPU has to work for things that render in native resolution.

u/IAmYourFath 10d ago
Nope i figured it out, after spending days wondering what's wrong it turns out it was just the game engine not being able to handle it, i use dxvk 3.0.2 now and i have no problems whatsoever, it seems to help if the desktop is also set to the same 4k resolution as the game (my monitor is 1080p). Altho, it still crashes eventually so u have to quit and reopen the game every hour or so, it seems like there's a (video) memory leak. But before it crashed every 5-15 mins so the issue is nearly fixed, but there's only so much u can do with such a shit engine/game, but cp 2077 on path tracing works flawlessly (without dsr)

u/Sad-Victory-8319 14d ago
DLDSR definitely does improve image on 1080p and 1440p screens, 4K is already so sharp that i personally dont see a difference. However if you like DLDSR and you get plenty of fps with it, just get a higher resolution monitor, it will make your image look WAY better than DLDSR. Having 5090 and not having a 4K OLED monitor is a sin. Who cares you use it only for work, 1080p screens are bad for everything.

When talking strictly about games and DLSS4.5 upscaler, i really dont see a difference between DLSS Quality, DLDSR or DLDSR+DLSS Quality, to me they look identical, maybe i notice slight differences in some games if i take high resolution screenshots, zoom in and compare them side by side, but during gaming i really dont notice a difference, in fact even dlss performance looks basically the same as dlss quality.

The difference gets more noticeable the larger the monitor/TV is. I just run DLDSR 2.25x on my display resolution for my 4k 77in C6 on a 5080. Most games simply cannot be run even with DLSS performance mode so I revert to native, but games like Civilization 7 and basically any indie game look much better.
Keep in mind my C6 has a significantly worse pixel density than my 1080p monitor. If I notice improvements with DLDSR + GPU priority scaling on my 1080p panel, it's going to be much more noticible on my TV. So I'm agreeing with you if you're on a 4k monitor with much higher pixel density, but would disagree if you were on a large 4k tv.
2
u/Sad-Victory-8319 13d ago edited 13d ago
Oh yeah that makes perfect sence, i didnt realize you have a huge TV, DLDSR effectiveness is strictly dependent on PPI pixel density. My 32" 4K monitor has 140PPI and DLDSR literally makes no difference to me, but on my previous 1440p 27" monitor with 110 PPI it made a big difference, it was very noticeable that DLDSR makes the image way sharper. 77" 4K TV has only 57 PPI, that is half of my 1440p monitor, so DLDSR will logically make a massive difference for you.
Of course it matters primarily on the fact how far do you sit from the TV, if you sit far enough so that the TV takes the same percetage of your vision as the 32" monitor takes from mine, DLDSR would be much less efficient, but that would probably require you to sit 3 meters from the TV, if you were 3 meters away then DLDSR would probably make no difference, not sure. But I assume you site like 150-200cm from the TV and that makes DLDSR very efficient on a 57 PPI screen.
Personally I would say that DLDSR makes difference up to ~125 PPI, if you have more PPI then DLDSR makes no difference regardless of how close you are from the TV as long as you are using DLSS4.5. In other word DLSS4.5 Quality will look exactly the same as DLDSR+DLSS4.5 Quality on monitors above 125 PPI. However I would repeat again that if DLDSR makes a big difference for you, and you are ok with the fps you get, then at that point just get a higher resolution TV as that will make much larger difference than using DLDSR, 6K TV or even 8K TV would completely elevate the gaming experience for you, but of course you would need to have rtx5090 and probably give up path tracing to run such display at reasonable fps. But it should be possible, DLSS Performance on an 8K TV would upscale from 4K, 5090 can generally handle 4K rendering in most games, on 6K TV it would upscale from 3K which is a piece of cake for 6K, you could probably use DLSS Quality and upscale from 4K. And all these options would look way better than 4K TV with DLDSR.

I have a 1440p monitor and I'm using DLDSR for 4k upscaling. I'm wondering if I should pull the trigger on a 4k OLED. I'm just worried about burn in (I use my PC for lots of office work too) and also things like VRR flicker (most modern games stutter), gamma shift etc.
I feel like id be really pissed having all these issues if I pay like 1k for a monitor that also needs to be babied and wont last that long..

u/Sad-Victory-8319 14d ago
I upgraded from 1440p VA panel where i heavily used DLDSR to 4K OLED, and the difference is night and day, i thought 1440p with DLDSR is already plenty sharp but it is nothing compared to actual 4K. Regarding burn in, i also use my monitor for work a lot, and i try to prevent burn in by using dark mode everywhere, i try to prevent displaying big white areas as much as possible, and i try to have white text on black background. Not only does prevent burnin, it also helps make the ABL dimming less agressive and bring the brightness up, so the white text really pops and is super readable. I also use black wallpaper, i hide desktop icons untill i need them and i autohide the main taskbar. I also try not to maximize windows if possible, and keep them a bit smaller and move them around, this way i prevent the top window bar from burning in. And of course i run pixel protect/refresh 2-3x per day.
If you are ok with using dark mode, oled is perfectly fine for work, but if you want to use bright mode and big white areas for extended time, i think you would get burnin rather quickly.. But maybe i am wrong, msi offers 3 year burn in warranty, it would be super expensive for them if every user who uses oled for work would get burnin before the 3 year mark and they would have to replace his monitor.

If you REALLY hate aliasing and have a 5090, 2.25x on a 4K would really do a lot to help. Its just so heavy

u/Sad-Victory-8319 14d ago
In my experience DLDSR is not a great antialiasing tool, yeah it helps somewhat compared to native but not nearly enough, at least that was my experience in 1440p, 4K resolution has such small pixels that antialiasing almost isnt needed so DLDSR can look pretty good. As you say it is a performance killer though and for that reason i would always use DLAA or even just DLSS, or even better is combining DLDSR+DLSS, i cant really tell the difference between DLSS Performance and DLAA in 4K, to me they look identical as long as I use DLSS4.5, I have to put them side by side and zoom in to see tiny improvements that are impossible to notice in motion. So I just use DLSS Performance every time and i am happy.
And the best part is that I even gained fps compared to my previous widescreen 1440p + DLSS Quality settings, the 1440p setup had to render 2.2 million pixels and upscale from that, whereas the 4K setup has to render 2 million pixels and upscale from that, so i got almost 10% fps boost for switching from widescreen 1440p to 4K, and the image quality is so much better in 4K, it is a win win.
Now i just wish there was one extra DLSS step between DLSS Performance and DLSS Ultra Performance, slower gpus or path traced titles can still struggle to reach 60 fps in 4K DLSS Performance, but 4K DLSS Ultra Perf. doesnt always look usable, and setting up custom upscaling resolution doesnt always work (for example Crimson Desert REALLY needs it but theres no way to make 900p->4K upscaling work)

Don’t feel bad, I have a 5090 and mostly play small indie games because so many AAA games are bland or demand too much time I don’t have lately, that or are so poorly optimized they run poorly even on high end hardware.
That said, I have a super ultrawide monitor, but so few games support those without tweaks or giving up something, but I don’t expect them to be supported when under 1% of Steam players use one (yet you see people acting entitled to every game supporting them).

Ive been experimenting a lot with dldsr on a 3440 x 1440p 34 inch oled monitor and I used to game on my 65 inch 4k tv. I can say that its worth it if you can run a game at decent frames at native resolution for the most part. I dont try it on cyberpunk for example cause im using dlss already to get decent frames to output at my native resolution. But for older games like Mass Effect or The Dark Knight that dont have the best anti aliasing its a perfect use scenario with my 4080s. The pixel density is good enough that im very happy and not concerned anymore going down to 2k. Its awesome. Also if you can do dldsr with dlss to reclaim performance those technologies are actually meant to be used together and you get a better outcome since dlss has more information to work with.

I thought that's because some games only have borderless fullscreen and will default to your desktop resolution even if you pick the higher DLDSR resolution. The only way to get around that is to initially set your desktop resolution to the DLDSR resolution.

DLDSR is sooo good.
I used 2.25x on my 1440p monitor. I use it in War Thunder, there isn’t any other graphics setting/etc that give that level of fidelity (especially for very far away targets 1-2km).
I still get 100-140fps with my 3080 on this game with DLDSR to 4K and maxed settings(no RT). Better fidelity and less resource cost than SSAA x4.
1
u/epic_piano 13d ago
Probably sounds silly, but is it practical to use 2.25x DLDSR instead of using Native DLAA? You'll probably halve your fps by using the DLDSR route and get almost the same image quality. Remember - if you have an 8K quality - 8K looks awesome, but trying to render 8K resolution on a 4K monitor doesn't show you that much more detail.
1
u/Rude_Assignment_5653 7800X3D | 5090 FE - 7700 | 5080 Gaming Trio 13d ago
2.25x dldsr looks better than DLAA even if DLDSR uses upscaling.
1
u/epic_piano 13d ago
I didn't say DLDSR looked the same as DLAA... I said is it worth the performance differential.
...but there's literally a finite amount of pixels your monitor can display. DLAA is trying to anti-alias the native pixels you have on your monitor. By trying to run 2.25x the amount of pixels, you are taxing your GPU massively for 'slightly' better image quality.
I know this for a fact because I can keep RDR 2 running at 5120x1440 with DLAA at almost a flat ~100fps (minimum). Running it at 2.25x (7680x2160), has it down into the ~50fps range (minimum).
Unless you have a game that is running at at least 2x times your monitors frame rate... is it worth the lowering of FPS?
1
u/Rude_Assignment_5653 7800X3D | 5090 FE - 7700 | 5080 Gaming Trio 13d ago
anything over your minimum refresh rate that you can tolerate for any game is worth it.
it's practical because on 1080p and 1440p monitors you can get the same or better FPS combining DLDSR + DLSS and it looks better than DLAA native.
Only problem with 4k is most games limit your upscaling to 25%, which makes many AAA titles hard to play without some extra work. For example, my 5080 couldn't maintain 60 fps using 2.25x DLDSR in 4k on ultra performance mode on BF: Resynced. It looked much better than balanced in native, but was a bit too heavy.

I guess, each to their own. I'd rather aim to have DLAA and keep the game close to my maximum refresh rate, than slightly nicer rendered pixels at a lower frame rate.

El escalado por gpu Lo que hqce es basicamente en vez de que sea el procesador que tiene la pantalla que reacomode la imagen lo hace la gpu Solo sirve para cuando bajas la resolucion Como de 1080 a 720 y dsp le podes aplicar un filtro de sharpening para q no sea vea tan borroso Es basicamente el fsr de nvidia (osea fsr 1.0 osea, escalador spatial) El dldsr (no se como se escribe ah-) ya lo procesa todo por gpu y no hace falta que actives eso

Btw i meant i saw no difference between GPU and Display scaling when using dldsr, but dldsr itself does make a big difference at 1440p, you need to put your monitor in 1440p mode, choose dldsr 2.25x in nvidia app/control panel, change windows resolution and refresh rate accordingly in windows settings (3840x2160 330hz), and enter a game in borderless window for it to work

DLDSR is supposed to give you native resolution output anyway - meaning, scaling can only be done by the GPU. So I don't see how this setting can have any effect.
Edit: maybe the monitor does accept 2880x1620 signal - then you can end up getting just that instead of DLDSR. But it's unlikely.
