we have a whole video about NVIDIA dlss and the cool features it offers but
according to the most recent steam Hardware survey only 52% of you have a
graphics card that supports dlss but what if I told you there's an
open-source alternative that any modern GPU can use what it's called AMD's
Fidelity FX super resolution or FSR and
version 3.1 just came out so lest you
think we're ingredia shills let let's talk about how FSR Works how it compares
to the aforementioned dlss and how to enable it in your favorite games like
dlss the overall idea of FSR is to
increase performance that is frame rate by rendering the game at a relatively
low resolution then using upscaling techniques to fill in the blanks and
produce the final image you see on your display NVIDIA's dlss accomplishes this
by training a proprietary AI model using a supercomputer but how how does FSR do
it FSR has actually gone through three revisions the first of which FSR 1 came
out in 2021 and is primarily concerned with correctly reconstructing the edges
of objects on the screen the algorithm does this by comparing gradients in the
original image to see how to reconstruct edges in the upscaled image after this
is done the image is sharpened and sent to your screen fsr1 typically gives
better results than more common upscaling techniques that displays would
perform on their own own but it does require you to have anti-aliasing
enabled in your game settings which means your GPU has to do some additional
leg work but FSR 2 released in 2022 can
work on more parts of the image than just the edges unlike fsr1 FSR 2 is a
temporal upscaler which is a fancy way of saying it analyzes previous frames to
determine what the next frame should look like this is closer to how dlss
works and provides a significantly nicer image than FSR 1 including more detailed
textures after FSR 2 applies its upscaling algorithm which works without
anti-aliasing being on in your game first it then does its own anti-aliasing
pass that takes the place of the builtin TAA of whatever game you're playing the
downside of FSR 2 though is that because it relies so much on previous frames it
can produce ghosting in fast-paced games
since the previous frames might be very different from the current frame FSR 2
is trying to upscale not all Fram are the same I learned that the hard way but
even though FSR hasn't even been out for all that long there's already an FSR 3
and we'll tell you all about it right after we thank the sponsor of this video
Odo to carve your own space in the digital world without a website is
madness with ODU you can design and get your very own website up and running in
no time at all thanks to their intuitive codefree drag and drop elements and if
you find yourself experiencing some writer block odu's AI copywriter is
there to help you out oh and did we mention that it's free it's free and you
can even get unlimited hosting and a fully paid custom domain name for the
first year visit the link in the description and start building your very
own website with ODU FSR 3 is based on
FSR 2 but it also includes frame generation so it's a little bit like how
motion interpolation on a TV Works where frames are completely created and
inserted between actual frames from The Source content in order to increase the
apparent frame rate aka the thing I turn
off on every single TV I ever use except in this case you want it because games
reviews on the image quality of FSR 3's frame generation have generally been
good but it should be noted that enabling frame generation can result in
higher latency between a controller input and what happens on your screen
but whether you'll notice comes down to what kinds of games you play how
sensitive you are to lag in general and whether you're using FSR 3 in
computationally heavy scenes where the frame rate starts to dip which can make
latency worse it should also be noted that issues have been reported when
trying to use FSR 3 image generation with variable refresh rate AMD
recommends that you try and keep your game's frame rate within your monitor's
refresh range to prevent tearing so your mileage may vary on a more positive note
FSR 3 does add its own native anti-aliasing mode which can be used
without upscaling if you want an alternative to traditional AA without
the other FSR featur feat the frame generation feature can also be used with
a different upscaler such as dlss in FSR
revision 3.1 and later good news if you have a RTX 2000 or 3000 Series GPU as
DSS's competing frame generation technology is only officially supported
with 4,000 series cards you're welcome NVIDIA no matter what flavor of FSR
you're using turning it on is just a matter of toggling it in the game
settings menu but keep in mind that there does need to be developer support
for for it so it won't work with every single game but AMD does offer a
solution called radon super resolution which is similar to fsr1 but will work
in any exclusive fullscreen game without that game's developers doing any extra
work but you need an AMD RX 5000 series
GPU or newer to run it as it's part of the AMD graphics driver and only AMD
gpus use that have you tried FSR in any
of your games what did you think about it we're let us know in the comments and
if you want to know more about NVIDIA's competing solution dlss go watch this
video next we just I'm so curious what's going on out there
