00:00:00,120 --> 00:00:06,680
we have a whole video about NVIDIA dlss and the cool features it offers but

2
00:00:05,040 --> 00:00:12,599
according to the most recent steam Hardware survey only 52% of you have a

3
00:00:09,880 --> 00:00:16,840
graphics card that supports dlss but what if I told you there's an

4
00:00:14,200 --> 00:00:23,720
open-source alternative that any modern GPU can use what it's called AMD's

5
00:00:20,119 --> 00:00:27,480
Fidelity FX super resolution or FSR and

6
00:00:23,720 --> 00:00:30,160
version 3.1 just came out so lest you

7
00:00:27,480 --> 00:00:34,719
think we're ingredia shills let let's talk about how FSR Works how it compares

8
00:00:32,480 --> 00:00:40,760
to the aforementioned dlss and how to enable it in your favorite games like

9
00:00:37,160 --> 00:00:43,239
dlss the overall idea of FSR is to

10
00:00:40,760 --> 00:00:47,800
increase performance that is frame rate by rendering the game at a relatively

11
00:00:45,160 --> 00:00:52,120
low resolution then using upscaling techniques to fill in the blanks and

12
00:00:50,160 --> 00:00:58,000
produce the final image you see on your display NVIDIA's dlss accomplishes this

13
00:00:55,239 --> 00:01:03,120
by training a proprietary AI model using a supercomputer but how how does FSR do

14
00:01:00,879 --> 00:01:08,560
it FSR has actually gone through three revisions the first of which FSR 1 came

15
00:01:05,840 --> 00:01:13,320
out in 2021 and is primarily concerned with correctly reconstructing the edges

16
00:01:11,240 --> 00:01:17,920
of objects on the screen the algorithm does this by comparing gradients in the

17
00:01:15,600 --> 00:01:22,799
original image to see how to reconstruct edges in the upscaled image after this

18
00:01:20,520 --> 00:01:27,240
is done the image is sharpened and sent to your screen fsr1 typically gives

19
00:01:25,560 --> 00:01:31,040
better results than more common upscaling techniques that displays would

20
00:01:29,079 --> 00:01:34,680
perform on their own own but it does require you to have anti-aliasing

21
00:01:33,000 --> 00:01:41,159
enabled in your game settings which means your GPU has to do some additional

22
00:01:36,960 --> 00:01:43,240
leg work but FSR 2 released in 2022 can

23
00:01:41,159 --> 00:01:49,320
work on more parts of the image than just the edges unlike fsr1 FSR 2 is a

24
00:01:47,119 --> 00:01:53,880
temporal upscaler which is a fancy way of saying it analyzes previous frames to

25
00:01:52,079 --> 00:01:58,799
determine what the next frame should look like this is closer to how dlss

26
00:01:56,520 --> 00:02:04,079
works and provides a significantly nicer image than FSR 1 including more detailed

27
00:02:01,399 --> 00:02:08,360
textures after FSR 2 applies its upscaling algorithm which works without

28
00:02:06,399 --> 00:02:13,720
anti-aliasing being on in your game first it then does its own anti-aliasing

29
00:02:11,280 --> 00:02:18,720
pass that takes the place of the builtin TAA of whatever game you're playing the

30
00:02:16,080 --> 00:02:24,239
downside of FSR 2 though is that because it relies so much on previous frames it

31
00:02:21,200 --> 00:02:25,840
can produce ghosting in fast-paced games

32
00:02:24,239 --> 00:02:30,160
since the previous frames might be very different from the current frame FSR 2

33
00:02:28,080 --> 00:02:33,640
is trying to upscale not all Fram are the same I learned that the hard way but

34
00:02:31,840 --> 00:02:38,080
even though FSR hasn't even been out for all that long there's already an FSR 3

35
00:02:36,599 --> 00:02:42,360
and we'll tell you all about it right after we thank the sponsor of this video

36
00:02:39,840 --> 00:02:47,360
Odo to carve your own space in the digital world without a website is

37
00:02:44,800 --> 00:02:51,640
madness with ODU you can design and get your very own website up and running in

38
00:02:49,400 --> 00:02:55,840
no time at all thanks to their intuitive codefree drag and drop elements and if

39
00:02:54,319 --> 00:03:00,280
you find yourself experiencing some writer block odu's AI copywriter is

40
00:02:58,519 --> 00:03:04,599
there to help you out oh and did we mention that it's free it's free and you

41
00:03:02,800 --> 00:03:08,640
can even get unlimited hosting and a fully paid custom domain name for the

42
00:03:06,799 --> 00:03:13,879
first year visit the link in the description and start building your very

43
00:03:10,239 --> 00:03:16,799
own website with ODU FSR 3 is based on

44
00:03:13,879 --> 00:03:22,159
FSR 2 but it also includes frame generation so it's a little bit like how

45
00:03:19,480 --> 00:03:26,879
motion interpolation on a TV Works where frames are completely created and

46
00:03:24,519 --> 00:03:32,040
inserted between actual frames from The Source content in order to increase the

47
00:03:29,000 --> 00:03:34,599
apparent frame rate aka the thing I turn

48
00:03:32,040 --> 00:03:39,439
off on every single TV I ever use except in this case you want it because games

49
00:03:36,799 --> 00:03:43,239
reviews on the image quality of FSR 3's frame generation have generally been

50
00:03:41,480 --> 00:03:47,599
good but it should be noted that enabling frame generation can result in

51
00:03:45,760 --> 00:03:51,720
higher latency between a controller input and what happens on your screen

52
00:03:49,840 --> 00:03:56,000
but whether you'll notice comes down to what kinds of games you play how

53
00:03:53,400 --> 00:04:00,120
sensitive you are to lag in general and whether you're using FSR 3 in

54
00:03:58,000 --> 00:04:04,519
computationally heavy scenes where the frame rate starts to dip which can make

55
00:04:02,159 --> 00:04:09,040
latency worse it should also be noted that issues have been reported when

56
00:04:06,200 --> 00:04:12,640
trying to use FSR 3 image generation with variable refresh rate AMD

57
00:04:11,200 --> 00:04:17,160
recommends that you try and keep your game's frame rate within your monitor's

58
00:04:14,599 --> 00:04:22,280
refresh range to prevent tearing so your mileage may vary on a more positive note

59
00:04:19,359 --> 00:04:26,199
FSR 3 does add its own native anti-aliasing mode which can be used

60
00:04:24,600 --> 00:04:30,520
without upscaling if you want an alternative to traditional AA without

61
00:04:28,600 --> 00:04:36,400
the other FSR featur feat the frame generation feature can also be used with

62
00:04:32,720 --> 00:04:39,199
a different upscaler such as dlss in FSR

63
00:04:36,400 --> 00:04:45,160
revision 3.1 and later good news if you have a RTX 2000 or 3000 Series GPU as

64
00:04:42,800 --> 00:04:50,039
DSS's competing frame generation technology is only officially supported

65
00:04:47,560 --> 00:04:54,400
with 4,000 series cards you're welcome NVIDIA no matter what flavor of FSR

66
00:04:52,520 --> 00:04:57,639
you're using turning it on is just a matter of toggling it in the game

67
00:04:55,880 --> 00:05:01,720
settings menu but keep in mind that there does need to be developer support

68
00:04:59,400 --> 00:05:06,440
for for it so it won't work with every single game but AMD does offer a

69
00:05:03,720 --> 00:05:11,880
solution called radon super resolution which is similar to fsr1 but will work

70
00:05:08,960 --> 00:05:17,520
in any exclusive fullscreen game without that game's developers doing any extra

71
00:05:13,840 --> 00:05:20,160
work but you need an AMD RX 5000 series

72
00:05:17,520 --> 00:05:26,199
GPU or newer to run it as it's part of the AMD graphics driver and only AMD

73
00:05:22,680 --> 00:05:27,960
gpus use that have you tried FSR in any

74
00:05:26,199 --> 00:05:32,560
of your games what did you think about it we're let us know in the comments and

75
00:05:31,039 --> 00:05:37,560
if you want to know more about NVIDIA's competing solution dlss go watch this

76
00:05:34,600 --> 00:05:42,319
video next we just I'm so curious what's going on out there
