Nvidia DLSS only works on some resolutions

[NumLock21]

It has been discovered by the guys over at Tech Power Up, that DLSS used by Nvidia RTX cards will only work on some resolutions and not others, and it also depends on the video card you get. The RTX 2060 in Metro Exodus, will only support DLSS at 1920x1080 and 2560x1440, but not 4K, while the RTX2080/Ti, DLSS only works when it's running at 2560x1440 and 4K, but not 1920x1080. Nvidia's response for this was

Quote

We contacted NVIDIA about this to get word straight from the green horse's mouth, hoping to be able to provide a satisfactory answer to you. Representatives for the company told us that DLSS is most effective when the GPU is at maximum work load, such that if a GPU is not being challenged enough, DLSS is not going to be made available. Accordingly, this implementation encourages users to turn on RTX first, thus increasing the GPU load, to then enable DLSS. It would thus be fair to extrapolate why the RTX 2080 Ti does not get to enjoy DLSS at lower resolutions, where perhaps it is not being taxed as hard.

Whatever Nvidia's excuse is to limit DLSS on certain resolutions, Many users probably won't be happy, a feature found on their expensive card, will only work under certain resolutions.

That explanation they gave is...misleading. A simple way of increasing the GPU-load is to simply...disable vsync/gsync/freesync. No, the reason for this limitation is that those tensor-cores can't handle high FPS -- if they let you turn on DLSS when the GPU isn't already taxed to the max, you'd quickly notice your FPS tanking simply because those tensor-cores ain't fast enough. If your FPS is already low(-ish), enabling DLSS won't hurt anymore and it'll seem like it's magically increasing your FPS instead.

 

Basically, NVIDIA wants to limit DLSS-usage only to situations where it won't hurt the technology's reputation.

They don't want DLVaseline memes.

Now I wonder if it will work on ultrawide (3440x1440, 2560x 1080) resolution.

Isn't that like "to run faster you first have to bind your hands and chop your legs off"?

 

Jokes aside, it sounds weird...

I can confirm, DLSS is completely broken at 21:9 ultrawide resolutions xd.

 

Useless, you pay a premium for a technology you can only use under their conditions lel.

The quote "It just works" seems very appropriate here... Yeah, "It just works" IF you do this and IF you do that other thing as well. Then it will work...

For real though - a weird decision, I wonder what is the actual cause behind this.

[The Benjamins]

Just another reason to never use DLSS, all the new features of the 2000s is a huge mess.

Do you even need antialiasing while running at such high resolutions?

For what though? You don't even need antialiasing at 1440p like you would at 1080p.

You can still see aliasing quite clearly on a thin objects. 

Also it depends on your screen size since the PPI/DPI varies also based on that.

So the other hugely lauded tech on the rtx cards is useless in at least 50% of situations. 

 

Do they really wonder why RTX sales have been poor. To recap, RTX " on" thus far is a sizable if not huge performance penalty and does not "just work". Implementation is not great either. DLSS is not the awesome sauce it was billed as now either. 

 

Yet Nvidia thought we were all going to swallow the RTX tax. To bad for all those who bought into the hype. 

 

I never thought I'd be hoping for Intel to bring competition the GPU market, AMD doesn't exactly seem poised the do much if anything in the way of competing.

While DLSS is impressive it was originally believed to be an AA replacement that also helped performance not just a plain old performance enhancer like Nvidia is treating it as now. Which sucks because we NEED better AA techniques that can properly AA textures and smaller geometry and not apply a filter like TAA does to attempt it. They broke throuigh real time ray tracing and teased us wit ha breakthrough of new AA replacement but took it away as it just actually being performance enchancement so it's "useless" otherwise (even though the AA it gives can be better than traditional AA and Super sampling given time for the AI to mature.)

any word on oddball resolutions like 1920x1200 or those superwide monitors? o_o

1920x1200 isn't an oddball resolution it's a standard resolution that's superior to 1920x1080.

Yeah true, the DLSS feature doesn't seem very useful IMO and its dumb that DLSS only works at certain resolutions depending on the game and the RTX GPU being used.

Imagine the flames, mockery, taunting and other things if someone else would make such thing, that doesn't seem to be that ready for the market (yet)...

 

Reminds be of the flamewars back in the day, when the nVidia side claimed that 32bit was awesome (though too slow), while the 3dFX side argued that 32bit is too slow anyway and 24bit Dithering is the best compromize...

 

Awesome - on paper.

In reality?? Pretty useless...

 

Just look at how long it took for FSAA to be useful...

Did you not see the asterisk next to that Nvidia statement.

Guess I'm screwed forever with my 16:10 2560x1600.

[xAcid9]

Can someone compare DLSS to FXAA/SMAA? 

[D13H4RD]

It just works!!!*

 

* - May require specific conditions for best results. NVIDIA cannot guarantee claimed performance outside of validated parameters. 

[FloRolf]

Oh man, if AMD wouldn't f#ck up so badly right now they could easily be king. Nvidia done goofed m8. 

[SkilledRebuilds]

MONTHS Old Hardware now....Transparency of None.

 

iE - Nvidia obviously won't mention anything that hurts them,... but seriously,.. people do like options do tweak further,..presets exist for those that don't.

Not full total control over some of the basic aspects of the technology....

 

[CTR640]

Another reason not to buy RTX GPU. Good job, nVidia, really good job.
