Have you ever wondered how video game graphics have become incredibly realistic? How can GPUs and graphics cards render such incredibly detailed scenes? Well, in this video we're going to explore how just a bunch of data in your computer gets turned into realistic graphics. Additionally, we'll take a quick look into Ray Tracing, DLSS or Deep Learning Super Sampling, and many other complicated aspects of video game graphics.
We at Branch Education love to play video games, so this video has been one of our favorite ones to make thus far. It's kind of like getting to look under the hood of your childhood car. Also, it was surprising that practically all video games use similar basic steps to render each frame. Furthermore, as a fun fact, to create this video our team used 1x 3090ti, 3x 3090s, and the model that we tore down was a 3090.
There are just sooooo many topics in the realm of computer graphics that we couldn't cover. If you're interested in part 2 where we'll cover things like UVs, Normal Maps, Shadows, Reflections, Specular Reflections, and much more, tell us in the comments.

I'm a professional graphics engineer and this is one of the best videos covering this topic. I will be using this video for newcomers to the field.

The amount of work behind this 20 minute video is amazing. I am not taking it for granted.

This is the best visualization of the rendering process I've ever seen. Thank you for your effort

Please continue to make these videos they are absolutely amazing. You focus on the parts that matter. The simple things. Adding in just the right amount of math and explanation to make it clear and concise. Explaining what we aren't covering in the video and where those concepts land the the scheme of things. Its just perfect. I would however watch endless videos no matter how detailed you get. This is actually one of my favorite channels on youtube. I remember watching my first video of yours about starlink and have been hooked since. You know how to tow the line between being bogged down in complexity and broadening the concept. Maybe i'm just a much more visual learner but to me everything makes perfect sense immediately. Its rare to be able to understand things so much better so quickly. Even when you cover things I am already familiar with it deepens that understanding with the visuals in a way my mind may have previously made more convoluted.

This channel, and this video, is the most underrated in the youtube algorithm. Instead of junkie videos that the majority consume, I wish it was videos like these that deserve the spotlight and recognition. This is amazing work and I hope there is nothing out there that forces you guys to slow down

I've been playing video games for over 30 years and been a professional graphic designer for over 12 and I've never seen such a clear and well produced video explaining how video game graphics work. VERY impressive.

The narrator is so chill and awesome to listen to. And the videos have the vibe of an old 80s-90s science video you'd watch in school. I love these

Another incredible detailed explanatory video! Thank you for taking the time to create it. Looking forward to more advanced topics.

This is genuinely a 20 min long master class and the fact that we are able to watch it for free is crazy. Thank you team branch Education for such awesome content.

As a game dev, this video will make my life that much easier as an introduction to newcomers to the field. Beautifully crafted, guys! Kudos!

This video left me with tons of questions, but now I actually feel equipped to know what those questions are and how to find the answers. This summarized the topic more clearly and more succinctly than dozens of articles, books, and even college classes I have taken. I have made a few games as part of classes or for myself but understanding how all of that ended up on the screen was still a mystery to me. This video was great. You took time to explain terminology and provide definitions. The way you explained how the matrix operations fit in without bogging a beginner down in needless details - well I can't even begin to say how helpful that was. Thank you so much, this was excellent.

Amazing video. Great amount of work went into making it and it shows!

What a wild video. 30 Years of gaming and never have i understood the mathematical complexity involved in the more modern games. Honestly breathtaking. Now playing AAA modded games in VR obviously takes these calculations to the next level. What a time to be alive. Great video guys!

Itās hard to believe that content of this quality is free. It amazes me the things that us humans have accomplished. Something that most people donāt give a second thought to, they just download a game and have fun playing it without thinking of the incredible engineering behind every pixel on their screen. It is truly awe-inspiring.

One of the ABSOLUTE best YouTube videos of all times. It's just amazing the detail and the same time simplicity to explain a topic.

I seen many times this video, after that Youtube showed me (I randomly opens it). And I have to learn much more of the complexity of what it does a GPU.
A true masterpiece, the first video that I have seen on 1440p on my smartphone (other videos lags a lot on it XD).
I really hope that you will release soon the videos where you go deeper on this argument, because is very interesting for me that are studying all that a gamer needs to know to choose a GPU for the next Gaming PC (I'm sorry for the bad english, I'm italian^^)
Good job, really!^^

I genuinely learnt more from this video than I did while studying āGraphics Engineeringā in college for an entire semesterš

As someone who works on
GPU Hardware Design, I didn't expect the video to cover so much of the subject. Thoroughly enjoyed the video and would highly recommend to beginners in the field.

I just found this channel, and it contains a bunch of topics I'm really interested in, instant sub. Great work.

This has been one of our favorite videos to make thus far. In this video, we covered the core steps of the video game graphics algorithm. We are debating making a 2nd video on some of the more advanced topics such as how shadows, reflections, and specular highlights (metal shininess) are calculated, as well as UVs, Normal Maps, Deferred Rendering, and other topics. However, 'part two' videos are tricky on YouTube because they rely on the viewer watching the first part, and there's always some level of attrition. So if you want a Part 2 / 2nd video on this topic, comment below on your interest.
