Together with @phammer.bsky.social, we'll talk about some of the rendering optimizations using triangle visibility buffers and VRS on Doom: The Dark Ages at GPC 2025. Hope to see some of you there!

Had a great time at the Doom release party in downtown Dallas last night with a bunch of the other engine guys. Met most of the US-side team face to face for the first time since joining id a few years ago - awesome people!

Yepp, indeed all projected-grid screenspace still, both for Doom and Indy. We do use some tricks to get around some limitations, like temporally reprojecting grid vertices to last frame to reduce aliasing under motion, but not perfect. We might switch to world-tessellation at some point.

Check out some of the tech we‘ve been adding for idTech 8 these past years. Really proud to be part of this amazing team!
Doom: The Dark Ages releases tomorrow, thumbs pressed people will enjoy some beautiful visuals and decent performance.

Sure! You can use e.g. tex2DGrad(.. ddx, ddy) with manually-computed derivatives.
If you re-order the compute shader threads to be in a morton-like order, you can use e.g. subgroupQuadSwapHorizontal/Vertical() to compute derivatives

Confirmed that this is indeed the software-VRS that's in place here. We're investigating some options to mitigate these places.

Its using a form of software-VRS instead

Hmmm, not 100% sure these are VRS issues, actually - could also come from the upscale sharpening or so. Thanks for pointing it out - fwding it with the team and we'll investigate

We‘ve finally shared some extensive look at Doom: The Dark Ages
Couldn‘t be more proud to be part of this team!

Just received my own physical copy, congrats on the release!
However, my copy seems to include some faulty pages of a different book in the middle? Or is it expected to include advertisements of some sorts?
