Nvidia DLSS only works on some resolutions

Recommended Posts

Posted · Original PosterOP

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.

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.

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.)

What baffles me is people foolishly buy into Nvidia's marketing of features that (in reality) net them lower performance...

 

I'm no fool for giving anyone credit for "what this could end up being X years later". No I give credit only on proven achievements.

 

And am glad majority of the market will not get conned into brand exclusive performance downgrades. Because fact is, that game developers know majority of their customers are on AMD hardware (consoles), and will not be stupid enough to waste resources implementing Nvidia's nonsense into their games when it can only work for a minority of customers.


Awareness is key. Never enough, even in the face of futility. Speak the truth as if you may never get to say it again. This world is full of ugly. Change it they say. The only way is to reveal the ugly. To change the truth you must first acknowledge it. Never pretend it isn't there. Never bend the knee.

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.

LOL YEAH seriously tho would DLSS not work? o_o i get the feeling (if it's the case) they're having troubles generalising the AI upscaler for any kind of resolution

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...
