www.graphicsprogrammingconference.nl might be a good fit for this - IIRC you're also based in EU currently? :)

Super cool! I'm really enjoing the game so far - huge congrats to the entire team.
Would be very interested in hearing a conference-talk about this tech and its early prototypes some time :)

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.

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

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?
