![]() He explains in far more detail than I could ever explain. You can find more information about this stage on Fabian's slides. Most of them related to sky and clouds.Ĭlouds, fog, and volumetrics are RDR2's prominent effects. Mud map: 2048x2048 R16_UNORM Sky and cloudsĪfter the mud pass, the game does a lot of work on GPU compute. This accumulated texture is used for Parallax Occlusion Mapping when rendering terrain. The game renders footprint textures of humans and horses into a displacement map along with trail textures of horse wagon wheels. Beside being a game mechanic, it makes envrionments more realistic. ![]() Because of that, the frame starts with a bunch of tasks like creating and deleting textures, shader resource views, unordered access views, updating descriptors, buffers, etc. RDR2 is an open-world game that streams data constantly. It should demonstrate most of the rendering techniques used in the game. It contains a lot of properties like spot and point lights, directional light (it's very subtle but it's there), buildings, NPCs, a horse, trees, vegetation, clouds, etc. It amortizes its work across multiple frames.īecause of that, I captured more than a single frame but this is the main one we are going to be focusing on. When it comes to a game like RDR2, it's almost impossible to see all the techniques in one frame. If you find any mistakes or things that can be improved, please reach out to me. So, there will be plenty of things that I don't understand. Since both RDR2 and GTA5 are from the same company and uses the same engine, some of the techniques from GTA5 present here as well.Īnother important thing is that, I am not a senior graphics programmer or anything like that. You can also read a graphics analysis of GTA5 by Adrian Courrèges here. Slides (At the bottom of the page), Video (starts at 1:58:00) You can check the slides from a SIGGRAPH talk by Fabian Bauer. If you want to learn from the actual developers, It just me analyzing RenderDoc frame captures. This isn't an official breakdown of the game. Today, we are going to look at some frame captures from the game and try to analyze graphics techniques used in the game. I know that I don't have a good rig but 25 FPS on medium settings? I finally managed to play the game and amazed by its graphics immediately.īut I got upset because I can barely play the game on medium settings at 25 FPS with a 1050Ti laptop GPU. Returned with a prequel for consoles in 2018. One of my favorite games of all time, Red Dead Redemption
