id Software’s Tiago Sousa and Axel Gneiting have shared some new tech details about Doom Eternal. According to Gneiting, Doom Eternal does not have a main or render thread. Instead, the game has jobs with one worker thread per core.
Fun fact: Doom Eternal does not have a main or render thread. It's all jobs with one worker thread per core.

Although Gneiting has not shared the exact number of jobs per frame, he estimated that it’s around 100.
I don't know the exact number, but I would guess in the order of 100 jobs. Jobs can spawn more jobs, but we also have preconstructed job graphs.

On the other hand, Tiago Sousa stated that the game’s Anti-Aliasing solution uses up to 32 temporal subsamples.
#DOOMEternal #idTech7 geek details: Anti-Aliasing uses up to 32 temporal subsamples (~32x SSAA). This iteration is also full quality on all platforms due heavy optimization (0.92ms on XB1 and runs async).

Furthermore, certain techniques in id Tech7 rely on temporal accumulation to distribute costs over many frames. Thus, disabling it will result in on many techniques/surfaces looking super noisy/aliased.
Ohh nice! >=120hz is the way to the future ?

Tiago Sousa has also confirmed that Megatextures is no longer available in Doom Eternal. Instead, id Tech 7 uses streaming textures.
Many reasons: overall quality / shading flexibility / disk space (both for final product and keeping development sane) / faster workflows, and so forth.
