making your games look better without having to drop a bunch of money on a new
graphics card is something that GPU manufacturers are keenly aware that
gamers want especially now that a new GeForce or Radeon card is going to cost
you a spare kidney on the secondary market now NVIDIA and AMD have both tried to
use their own secret sauces to make this happen both NVIDIA's dlss and AMD's fsr
have made plenty of headlines recently but team green is adding another feature
to its arsenal that it hopes will give it a leg up on AMD and maybe give you a
leg up in your games they call it dldsr
or deep learning dynamic super resolution and if that sounds familiar
it's because NVIDIA's regular dynamic super resolution you know without the
deep learning part has been with us since the days of the gtx 970 and 980.
so let's talk about what exactly that is and how deep learning improves upon it
regular dsr is a super sampling technique basically it uses your
graphics card to render your game at a higher resolution than what your monitor
natively supports then it scales that down to match your screen this produces
better looking images than just rendering at your display's native resolution
but why well dsr more specifically works by
taking samples of groups of neighboring pixels from the higher resolution
rendered image and blending them into a single pixel that you see on your lower
resolution display to make the resulting image more accurate this is essentially
the same way that super sample anti-aliasing or ssaa works
ssaa has been around for longer than dsr but games had to implement it
individually dsr has the advantage of not requiring work from game developers
and also puts the image through NVIDIA's own filter that takes into account
additional surrounding pixels to further improve image quality dsr has a habit of
making images a little softer than traditional ssaa though meaning that
some gamers like it and others don't regardless it's a popular way to improve
image quality especially as it allows more granularity with exactly how hard
you want your GPU to work instead of rendering the image at two times or four
times your monitor's resolution you could specify something like 2.25 times
depending on how powerful your GPU is but both dsr and ssaa are very
computationally expensive since you're basically asking your GPU to do way more
work and then throw away most of it that is where dl dsr comes in it
leverages the tensor cores in rtx series gpus that are designed with machine
learning and ai in mind we'll tell you about how dldsr works right after we

to freshbooks.com techquicky the idea behind dldsr is that
the neural network and the tensor course can figure out what the image should
look like by sampling a smaller number of pixels than regular dsr or ssaa one
example NVIDIA gave was from the game prey which was rendered at 1620p rather
than 4k then downscaled to 1080p
this was accomplished with nearly no frame rate drop compared to native 1080p
rendering and the image actually looked a little better than the traditional dsr
image that downscaled all the way from 4k similar to regular dsr dldsr doesn't
need per game support so it can actually make your older games look refreshed but
if you're using a title that supports dlss you can combine the two features
for an extra quality boost without sacrificing too much performance
don't expect it to work miracles though early reviews have said that the quality
improvement over regular dsr is pretty marginal and of course turning up the
scaling factor is still going to slow your frame rate down just that the
impact won't be as huge as it would be with traditional super sampling you'll
need an rtx card to take advantage of dldsr but don't feel completely left out
if you have a card from team red as AMD is set to launch its own ai-based Radeon
super resolution technology in early 2022 which should work on any rd and a2
GPU AMD cards at least for now don't have
dedicated machine learning cores like NVIDIA's do so it'll be interesting to
see how the two super sampling methods ultimately stack up against each other i
just hope they'll both be super get it because it's super resolution
