However this time, everything is fully forward rendered omitting the G-Buffer. Doom 2016 was mostly forward rendered with a thin G-Buffer for screen space reflections. Just like its predecessor, Doom Eternal is using a forward rendering pipeline. It’s an interior with a few enemies and a large portion of volumetric lighting. We’re looking at a section in the game close to the start. With Id Tech 7, the engine has moved away from OpenGL and is entirely built with a Vulkan backend allowing them to make better use of current generation GPU features, bindless resources in particular. If you haven’t played the game yet, don’t worry about spoilers! The section I used for this study is in the beginning of the game which doesn’t give away any of the details. I do not in any way support the reverse engineering for malicious purposes and stealing intellectual property. I do want to stress here that these studies are absolutely nothing more than educational. Some passes might not be covered here because they are very similar to Doom 2016 and are well covered in Adrian Courreges’s study. In this breakdown I aim to stay at a high level and not go too in-depth of each rendering technique/pass.

I believe these graphics studies give a lot of insight into how certain rendering problems are solved in a AAA game and are greatly educational. This frame breakdown is inspired by Adrian Courreges’s study on Doom 2016. Doom Eternal has improved in many areas of which a few are worth investigating which I will try to cover in this frame breakdown. Doom 2016 has inspired me greatly on a technologic level due to its simplicity and elegance while still having a high visual quality. It’s developed using the 7th iteration of id Tech, id Software’s in-house game engine. Doom Eternal is the successor of Doom 2016.
