I will soon be setting off for a weekend in the mountains, so not at the moment. Internet dead zone over there, so can't do anything until Monday or Sunday evening at the earliest.

As for evaluating DLSS i think it really makes sense to ask game developers and especially they graphics people what they think.


Anyone else may have their personal opinion - and for instance like that something may look sharper with DLSS on. But if that was not the intent of the developers then it becomes more like a 'loudness' button on your old hifi. You may like the result, but what is playing is now quite far from the artists intentions.


It may well be the other way around - that DLSS on come closer to what was intended.


Only way to know, is to ask the developers.

Ray tracing on the other hand imo makes it look either the same or worse. Not much improved and certainly not enough for the performance hit.
It's because we're so used to seeing bad shadowing hacks to add some level of occlusion. Those soft shadows from those characters ooft.

You don't really have developer intent with DLSS, it's a neural network based algorithm with the training based on the game itself ran at an extreme resolution, with the desired input as the game at a normal resplution, there's no fine tweaking on the individual basis(while a developer could manually play with the training weights in the neural network this shouldn't be desirable or necessary), really you want the back propagation algorithm to work all the weights out itself from the input. The reason DLSS improves with time is because either
A) The algorithm has spent more time training (refining it's internal weights to produce the desired output from input)
B ) The algorithm was originally trained to work with a notably different input (different resolution, aspect ratio or even certain settings to the original training input could feasibly have an impact)

Neural networks are cool when they work right, you just feed in an already sorted or correct data set and let the weights adjust themselves till the network fires out the right outputs for the inputs you want, but the lack of ability to easily manipulate that algorithms functionality directly, particularly with deeper networks, without knowing and understanding how all the internal weights would impact the result, which is near impossible for stuff neural networks are best used on(very abstract wide data sets), makes them a real pain(or practically impossible) to try and "quickfix" manually or add functionality or intent in later(think accidentally racist neural networks as a result of oversights during training and stuff) so often they just get retrained which is a pretty long compute intensive process.

#14 if your reply was to me, then I maintain that the developers are the best people to judge the end result after DLSS. Everyone else is entitled to their opinion, but it remains only an opinion based on personal preferences.



Developers can say if the result is better, worse or about the same compared to traditional rendering. Only they know what they are aiming for - and even traditional rendering has it limitations so it is not necessarily the perfect picture that everything else should be compared to.



How it works is meaningless in evaluating the results (although interesting) :-)

Yeah I just mean, the game developers have no influence on the results of DLSS, the training process is done by NVidia on their own supercomputers, and the algorithms themselves have no developer influence, it's kinda a black box to the gaming devs, but yeah I agree they should have the ultimate opinion on how their artwork is meant to be viewed (Although I think ultimately beauty is in the eye of the beholder regardless of whether that beauty is an accurate portrayal of the art as intended).

This is true but if it's so hard to distinguish between the two but one takes away 40% of your framerate, it's not worth it.
