What is this DLSS stuff? Should I run it on my games?

>>714826605 (OP)
If you don't need it, don't run it.

it lowers your resolution to give you better fps.
pc gamers have been doing this since the 90s. you played at 800x600 or 1024x768 if you couldnt run at native.

>>714826605 (OP)
It means running your game at a lower resolution internally and then AI upscaling it to your screen's resolution.

>>714826605 (OP)
No don't do it. You will create mustard gas

>>714827264
I don't want that shit, AI upscaling will ruin everything

voodoo magic if you can't tell the difference

decreases resolution for more fps.
if you stand still like OPs picture you dont notice it but when you move then you see the lower resolution artifacts

That’s frame generation specifically, you can (and always should for that very reason) use DLSS without framegen.

DLSS4 is when the bullshit Jensen was spewing is actually correct. You can force it in nvidia app or with DLSS swapper. There's no ghosting, artifiacting, or other weird issues. It's fucking spooky. Dlss2 and 3 are honestly not that good and the critics are right.

After using it for a while, I conclude that 90% of the time it’s free performance and you should use it.

DLSS4 is worse than FSR4. Multiple things wrong with DLSS on the right if you're not blind.

>There's no ghosting, artifiacting, or other weird issues
Untrue, it causes issues with volumetric lighting. You can see it a lot in games like Expedition 33 which have a lot of god rays, or games like Control, Stellar Blade, and a lot others. It's nigh flawless in anything but this one area though.

I have a 5080 and I turn that shit off. Ruins image quality.

DLSS4 and FSR4 are basically free performance and look better than native because native has forced TAA by the game which is dogshit. The TAA pass in DLSS and FSR is far superior to whatever games use. Obviously, native + MSAA out the wazoo would look sharper but it's not a thing nowadays.
Framegen is a mixed bag. Below input 60fps it's dogshit but above it's fine as far as I'm concerned. Some people don't like it at all.
The best thing you can do is not listen to all of us retards on /v/ and just test it yourself. You like it? Keep it on. It's shit? Turn it off. Simple as.

DLSS4 is sharper and resolves more detail but it has more artifacts. FSR4 is closer to DLSS3 in stability, it's like a DLSS3.5.
DLSS4 really shines when you upscale from 1080p to 4K (Perf mode) for a massive perf uplift with surprisingly little image quality loss but I think FSR4 has better Quality mode because it's less aggressive.
In a path traced game that shits itself above 1080p on a 5090 I'd rather have DLSS4 but for all other games I'd rather have FSR4.

DLSS is Nvidia's "AI assisted" upscaler.
As the name implies, it renders the game at LOWER resolution, then uses some clever guesswork + filters to scale it up to your screen res, making it look... "less shitty" than just doing typical bilinear upscaling.

AMD has its own version called FSR, and Intel joined the fight with its XeSS.
These upscales become a cheap crutch for lazy devs who cannot optimize their shit. It's practically essential if you wanna use real-time Ray Tracing and shit, or play at extra high resolutions on modest hardware.

To make it worse, all this essentially relies on the extra blurry Temporal Anti-Aliasing to smooth out the otherwise very noisy and ghosting-filled image.

The next cancer it has brough is the Frame Generation, which even fakes performance. So you got input lag, visible smearing, and other noisy artifacts.

tl;dr: Don't use any of this unless you reeeally have to.
Avoid games where you HAVE TO use it. Mostly Unreal 5 slop.

I turned on DLSS4 and it made the game look really weird and mushy

>>714827608
>That’s frame generation specifically
Incorrect.
It's just TAA's temporal frames being poorly masked and cut out, as usual.
Yes, ALL upscalers do rely on TAA.

You can see how much it adds to the overall final look in games like Deep Rock Galactic, that has separated AA and uspcaler options. TAA with 10% render res, no upscalers, with some Sharpen filtering, looks near identical to older FSR.

>proprietary "technology"
I seriously hope you don't do this.

>dlsstranny doesnt post proof

dlss is only good at "ultra quality" settings which is only available in a select few games. it runs around .77 resolution instead of the scuffed .66

It is an algorithm that is trained on high resolution, and then when it observes the low resolution image, it can reconstruct it as it would be at a higher resolution. Since NVidia GPUs have dedicated chips for this, the process is fast enough for imagem reconstruction to be in real time.
The problem is that it is a temporal solution. The longer you stay on the same image, the better the reconstruction. The effect collapses completely when you are moving and something in the foreground is blocking the background constantly, as in the pic related, where the fence near the screen is constantly blocking the image behind it, so when you move there is a severe degradation in image quality.

>but that's caused by TAA!
No, you can clearly see that the resolution as a whole has been affected on the moving screen, you can see fewer pixels on the fence, for example

>but it's imperceptible in real conditions
In fact, the effect is always noticeable, to a greater or lesser extent. The moving image is always of poorer quality than the image when you are stationary, with DLSS turned on.
