1 00:00:00,240 --> 00:00:08,200 oh boy I can't wait to play the new Indiana Jones 2 00:00:04,319 --> 00:00:11,120 game huh hang on a minute Billy for 3 00:00:08,200 --> 00:00:16,080 modern games you'll need Modern Hardware with Ray tracing Ray tracing what's that 4 00:00:14,879 --> 00:00:21,840 Mr Murdoch why it's quite an old technology 5 00:00:19,119 --> 00:00:26,560 but now done in real time thanks to powerful accelerators in your GPU that 6 00:00:24,880 --> 00:00:32,640 sounds expensive it is very expensive but you 7 00:00:30,160 --> 00:00:40,960 don't want your games to look ugly do you ugly like you well I guess not but I 8 00:00:38,920 --> 00:00:48,399 don't have enough money for a new GPU what can I do it's easy you just need to 9 00:00:44,360 --> 00:00:50,960 find a

00:01:13,119 --> 00:01:19,720 the great circle is the first game that was developed from the ground up to use 15 00:01:17,000 --> 00:01:25,240 ra tracing not as an option to make the lighting a bit more realistic but as a 16 00:01:21,720 --> 00:01:28,000 core required component of the game so 17 00:01:25,240 --> 00:01:32,880 we've set up two test systems one using the latest and greatest at the time of 18 00:01:29,600 --> 00:01:34,560 film NVIDIA's RTX 490 and one using 19 00:01:32,880 --> 00:01:39,399 NVIDIA's entry point into R Trace lighting Splendor the60 we're at 15 20 00:01:37,360 --> 00:01:43,280 frames that being said on both PCS we've set everything to Max on the 490 side 21 00:01:41,640 --> 00:01:46,640 we're still 4K native we have everything turned on except for path tracing 22 00:01:45,360 --> 00:01:51,360 there's still a lot of raate tracing that's happening like the reflections you can see in the window big thing I've 23 00:01:49,640 --> 00:01:56,240 noticed is that even in raid Trace games there's still just visual anomalies like 24 00:01:53,880 --> 00:02:01,079 his hair kind of changing color we are consistently above 60 frames a second 25 00:01:57,960 --> 00:02:03,479 Which is far above what I expected in 26 00:02:01,079 --> 00:02:09,080 this scenario but there is one thing NVIDIA really bunged up and that's the 27 00:02:05,719 --> 00:02:11,680 messaging we call RTX Ray tracing but in 28 00:02:09,080 --> 00:02:16,599 truth most games even this one only switch to Global Ray Trace illumination 29 00:02:14,160 --> 00:02:21,480 if you turn on path tracing I'm very impressed with the 49s ability to do 30 00:02:19,319 --> 00:02:24,879 over 60 frames a second and I've had to verify the settings many many times to 31 00:02:23,319 --> 00:02:28,640 make sure that I'm not secretly using dlss but that's going to tell you 32 00:02:26,599 --> 00:02:34,280 nothing about how the starter point for Ray tracing is going to do the 2060 and 33 00:02:31,480 --> 00:02:37,040 immediately you'll notice that the 2060 has a bit of challenge giving us the 34 00:02:35,560 --> 00:02:42,920 performance we'd like to see and so why don't we turn down some settings and give this thing a chance one thing to 35 00:02:39,760 --> 00:02:44,760 note is that Indiana Jones does a vram 36 00:02:42,920 --> 00:02:48,519 test when it boots if you have 12 or less gigs of vram it's it's going to set 37 00:02:46,440 --> 00:02:53,640 it to the lowest settings if you use a custom exe you can actually boot the 38 00:02:50,680 --> 00:02:56,680 game and skip that vram check uh to get access to those settings but uh 39 00:02:55,519 --> 00:02:59,840 unfortunately if you try and turn them on the game will crash actually we're 40 00:02:58,599 --> 00:03:05,040 going to leave 4K we're going to turn turn on some dlss baby 23 frames a 41 00:03:03,239 --> 00:03:09,200 second this is incredible even with an internal resolution of 1080p we are 42 00:03:07,040 --> 00:03:12,879 still having around 20 frames a second what if you have a 2060 and you want to 43 00:03:10,560 --> 00:03:17,840 make it actually run let's turn down some settings this game is running on 44 00:03:14,440 --> 00:03:20,080 the 2060 at a native 1080p High settings 45 00:03:17,840 --> 00:03:24,159 and it looks drastically worse which is no surprise but this is still a rate 46 00:03:22,159 --> 00:03:28,519 Trace experience if you bought your card 6 years ago you would still be able to 47 00:03:26,080 --> 00:03:31,920 play these games in Fairly High Fidelity oh those Reflections are 48 00:03:30,360 --> 00:03:36,640 oh remember when there was bright light reflecting on the floor from that window 49 00:03:33,920 --> 00:03:42,159 David remembers now it's clear that the 2060s first generation Our Tor were not 50 00:03:40,000 --> 00:03:47,000 chosen wisely in terms of future proofing but as you can see you don't 51 00:03:44,599 --> 00:03:51,599 need full rayra Global illumination for a game to look really impressive and it 52 00:03:50,239 --> 00:03:57,000 could be argued that NVIDIA's big selling point for this generation 53 00:03:54,200 --> 00:04:00,760 somewhat came true even if lonus wasn't wrong that you'd be better off waiting 54 00:03:58,120 --> 00:04:05,120 for a second third or fourth four or fifth gen card but why are we switching 55 00:04:02,879 --> 00:04:10,920 in-game lighting to Ray tracing more importantly why are we doing it now it's 56 00:04:08,280 --> 00:04:14,519 been used in film for decades and long before it was a selling feature on the 57 00:04:12,200 --> 00:04:18,359 side of GPU boxes even video games were using it to create the pre-bake lighting 58 00:04:16,239 --> 00:04:22,199 Maps used in traditional rendering we'll get to that but first you may already 59 00:04:20,759 --> 00:04:26,479 know the difference between path tracing and rasterization but let's lay them out 60 00:04:24,560 --> 00:04:30,160 just in case rasterization is the process of converting vector graphics or 61 00:04:28,639 --> 00:04:34,880 polygons and their inter intersecting points into a raster image which 62 00:04:33,039 --> 00:04:39,199 consists of pixels shaders are then applied that best approximate what those 63 00:04:37,000 --> 00:04:43,960 pixels should look like based on lighting texture and material properties 64 00:04:41,520 --> 00:04:48,919 path tracing often used interchangeably with the term Ray tracing even though 65 00:04:46,120 --> 00:04:53,080 they aren't exactly the same thing simulates the path of light rays as they 66 00:04:50,960 --> 00:04:56,880 travel through a scene hitting objects bouncing reflecting refracting or being 67 00:04:55,520 --> 00:04:59,720 absorbed Based On A material's Properties there are numerous methods 68 00:04:58,520 --> 00:05:05,440 that impact the accuracy of the simulation recursive Ray tracing for instance has Shadow rays that are sent 69 00:05:03,320 --> 00:05:09,600 out at each Ray intersection Point towards light sources and Photon mapping 70 00:05:08,080 --> 00:05:13,759 emits light particles from the light sources of a scene in a preliminary 71 00:05:11,160 --> 00:05:18,960 rendering pass but the principle of both Ray tracing and path tracing Remains the 72 00:05:15,479 --> 00:05:21,960 Same simulate light by tracing the paths 73 00:05:18,960 --> 00:05:24,680 of rays through a scene how many Rays 74 00:05:21,960 --> 00:05:30,360 you ask well that depends but the short answer is if you want to do it right a 75 00:05:27,440 --> 00:05:34,400 lot and when you do it right it offers a big advantage in terms of realism 76 00:05:32,639 --> 00:05:38,199 especially in scenes with Dynamic lighting like open worlds with day and 77 00:05:36,199 --> 00:05:43,080 night cycles as for why we're doing it now well it was inevitable the industry 78 00:05:40,880 --> 00:05:47,840 has wanted to for a long time and for good reasons don't take my word for it 79 00:05:45,160 --> 00:05:51,680 or inv videas but Pixar describes it as conceptually and mathematically simple 80 00:05:49,919 --> 00:05:55,520 and elegant that means that not only does Ray tracing code take up much less 81 00:05:53,720 --> 00:05:59,080 storage than the large light Maps we need for pre-baked lighting but no 82 00:05:56,960 --> 00:06:02,440 longer making those light Maps or adding extra lights to simulate indirect 83 00:06:00,800 --> 00:06:06,680 lighting should both save developers time and in result make for prettier 84 00:06:05,000 --> 00:06:10,080 games that was one of the key sales pitches for rate tracing that the 85 00:06:08,039 --> 00:06:14,319 reduction in manh hours outweighs the increased Hardware costs the only 86 00:06:12,080 --> 00:06:19,319 problem is that in the context of gaming The increased Hardware cost falls on the 87 00:06:16,639 --> 00:06:23,319 gamers whose gpus now need to perform those lighting simulations continuously 88 00:06:20,960 --> 00:06:28,080 every time they play a game Power build what power build and there are other 89 00:06:25,440 --> 00:06:32,440 costs NVIDIA has taken a lot of our money during RTX is awkward adolescence 90 00:06:30,479 --> 00:06:37,759 and maybe more importantly there's a cost in performance the most expensive 91 00:06:35,039 --> 00:06:43,240 gaming GPU at least until you can get its replacement over here is the RTX 490 92 00:06:40,759 --> 00:06:47,919 it has over three times the ray tracing prowess of the underwhelming first 93 00:06:45,120 --> 00:06:52,960 generation RTX cards and still can't consistently render a native 4K 60 Path 94 00:06:50,880 --> 00:06:59,759 traced experience even the newly announced $2,000 RTX 5090 is advertised 95 00:06:57,360 --> 00:07:03,960 to only hit 28 frames per second natively in cyberpunk with all the ray 96 00:07:01,720 --> 00:07:09,080 traced bells and whistles AI assisted upscaling with dlss is meant to make up 97 00:07:06,360 --> 00:07:15,440 for that and if my lovely assistant will move oh yeah you can see clearly it can 98 00:07:12,919 --> 00:07:19,319 deliver impressive results but from talking to one of pl's old games 99 00:07:17,000 --> 00:07:22,960 industry contacts Gamers aren't the only ones feeling like this transition might 100 00:07:21,360 --> 00:07:28,319 have been rushed a little bit see the pitch to developers including to our 101 00:07:24,960 --> 00:07:30,240 contact was of course Time Savings but 102 00:07:28,319 --> 00:07:34,599 the time that they saved from less manual lighting work ended up getting 103 00:07:32,160 --> 00:07:38,800 replaced with more time testing and optimizing performance on those 104 00:07:36,240 --> 00:07:43,199 underwhelming early generation cards optimization that usually resulted in 105 00:07:41,000 --> 00:07:47,240 turning down visual settings which in many cases left us with image quality 106 00:07:45,400 --> 00:07:51,000 that didn't look that much better than traditional rasterization as hard run 107 00:07:49,280 --> 00:07:55,000 box pointed out in an excellent recent deep dive those compromises caused some 108 00:07:52,919 --> 00:07:59,520 glaring issues such as noise and artifacting appearing as a a boiling 109 00:07:57,599 --> 00:08:03,280 effect those can be caused by low r counts needing to accumulate lighting 110 00:08:01,080 --> 00:08:07,199 information over multiple frames and suboptimal D noising techniques if you 111 00:08:05,520 --> 00:08:11,599 haven't experienced rate tracing at home it can be hard to tell sometimes YouTube 112 00:08:09,479 --> 00:08:15,039 compression and screenshots will cover a lot of those sins furthermore devs are 113 00:08:13,759 --> 00:08:20,000 still learning how to implement ra tracing both technically and artistically and the available tools are 114 00:08:18,360 --> 00:08:23,840 more rudimentary than their rasterized equivalent for example our contact set 115 00:08:22,039 --> 00:08:27,919 that key features such as light linking where lights will affect certain objects 116 00:08:25,440 --> 00:08:31,280 and not others are not as simple to use in Ray traced scenes some some of you 117 00:08:29,759 --> 00:08:35,599 might be old enough to remember the era of Bloom video game Graphics where every 118 00:08:33,560 --> 00:08:38,440 surface was slathered in a soft fuzzy glow that made it look like you were 119 00:08:36,640 --> 00:08:41,919 playing the game in a foggy mirror games like Burnout Paradise Twilight Princess 120 00:08:39,959 --> 00:08:46,440 and Oblivion come to mind and just as Bloom and motion blur and depth of field 121 00:08:44,480 --> 00:08:51,240 and other visual tricks went from flashy and new to overused and disgusting to 122 00:08:49,200 --> 00:08:55,320 intelligently applied I think raate tracing will hit those same milestones 123 00:08:53,160 --> 00:09:00,040 in due time strangely enough the strongest use case today for raid 124 00:08:57,000 --> 00:09:01,600 tracing in our opinion is the dazzling 125 00:09:00,040 --> 00:09:06,320 effect it can have when implemented into older titles either through discrete 126 00:09:03,480 --> 00:09:09,680 remasters custom mods or RTX remix NVIDIA's Suite of modding tools designed 127 00:09:08,000 --> 00:09:14,320 to make transformative upgrades of old PC games super easy I recently played 128 00:09:12,640 --> 00:09:19,200 through the original fear with added rate tracing via reshade and it was n 129 00:09:17,160 --> 00:09:23,600 transformative even though it pushed a 20-year-old game back to sub 60fps 130 00:09:21,600 --> 00:09:27,279 performance part of that performance hit is the hybrid raster and R Trace 131 00:09:25,560 --> 00:09:31,320 rendering committing to full rate tracing can actually improve performance 132 00:09:29,079 --> 00:09:35,720 like we've seen in Metro Exodus enhanced Edition or Indiana Jones so once raid 133 00:09:34,279 --> 00:09:39,680 tracing Tech has evolved to the point where most games fully transition to 134 00:09:37,959 --> 00:09:45,040 raid Trace rendering we may experience a bump in overall playability and maybe 135 00:09:41,760 --> 00:09:46,640 just maybe GPU makers can reduce the die 136 00:09:45,040 --> 00:09:52,920 space use for raster performance in exchange for even more raid tracing 137 00:09:48,200 --> 00:09:55,120 prowess or dare I say cost savings gosh 138 00:09:52,920 --> 00:09:59,760 that would be real nice the worst part of all this is that until we fully solve 139 00:09:57,399 --> 00:10:04,240 the chicken egg problem these issues will linger and the transition is 140 00:10:02,200 --> 00:10:09,160 clearly going to take some time I mean nearly one in every 30 PC Gamers is 141 00:10:06,600 --> 00:10:14,800 still running a 1060 for God's sake that came out in 2016 so I don't blame you 142 00:10:12,120 --> 00:10:19,560 guys for asking yeah it's pretty but is Ray tracing even worth it worth it like 143 00:10:17,519 --> 00:10:25,680 our new more compact commuter backpack at LTC store.com okay Jokes Aside only 144 00:10:23,120 --> 00:10:29,560 you can answer that question but what I can say is that no matter who you are 145 00:10:28,120 --> 00:10:33,240 you've got your head in this sand if you think that R tracing isn't happening and 146 00:10:31,560 --> 00:10:37,320 that you won't need it at some point I mean I remember back when people thought 147 00:10:35,240 --> 00:10:41,320 that fancy mesh shaders were just deployed to sell new graphics cards but 148 00:10:39,399 --> 00:10:45,079 I think in hindsight most people would agree now that we're better off for 149 00:10:43,160 --> 00:10:50,240 their widespread implementation I mean Allan Wake 2 looks incredible and runs 150 00:10:48,000 --> 00:10:54,040 well on lower-end Hardware as long as it's somewhat recent and has an 151 00:10:52,079 --> 00:10:59,800 up-to-date feature set but these things take time and I can hear a lot of you 152 00:10:56,680 --> 00:11:01,160 saying well yeah sure it's cool but 153 00:10:59,800 --> 00:11:07,079 I'm going to wait till it can be done natively with real frames no AI but I 154 00:11:05,160 --> 00:11:10,880 think it's becoming clear that that's not happening the real solutions are 155 00:11:09,360 --> 00:11:14,839 going to come in the form of optimizations like improvements to 156 00:11:12,880 --> 00:11:19,720 proprietary Solutions like dlss Ray reconstruction or generalized shortcuts 157 00:11:17,279 --> 00:11:25,040 like better distribution rate tracing because the thing is even in offline CG 158 00:11:22,800 --> 00:11:28,519 rendering studios are still using optimized shortcuts instead of brute 159 00:11:26,639 --> 00:11:33,880 forcing more rays and that's when we're talking about some sometimes 24 plus 160 00:11:30,880 --> 00:11:36,560 hour render times for a single frame so 161 00:11:33,880 --> 00:11:41,160 if you want your game to hit 60 plus frames per second you're going to have 162 00:11:39,000 --> 00:11:46,959 to accept that some Corners are going to be cut to bring the time down um 5.2 163 00:11:44,680 --> 00:11:51,839 million times really I don't think the problem is real-time rate tracing itself 164 00:11:49,279 --> 00:11:56,120 or even the AI upscaling techniques but rather that we've been forced to live 165 00:11:53,480 --> 00:11:59,560 through and pay for their infancy once we've worked through the current 166 00:11:57,200 --> 00:12:03,880 shortcomings we could see r traced motion blur and depth of field that can 167 00:12:01,880 --> 00:12:08,200 push cinematic realism to a whole other level or Hardware level support for 168 00:12:06,200 --> 00:12:13,240 advanced features like bidirectional path tracing to reduce noise at an equal 169 00:12:10,600 --> 00:12:17,639 render time and maybe even the promise of easier developer side implementation 170 00:12:15,600 --> 00:12:22,519 actually coming true so instead of seeing the new Indiana Jones as the 171 00:12:19,360 --> 00:12:24,720 harbinger of GPU pain and suffering I'm 172 00:12:22,519 --> 00:12:30,120 choosing to see it kind of like the hint of a whisper of
