A dive into the AMD driver workflow
I ended up getting a response from high level people at AMD. It was still very light on any real technical information, but it did include some great phrases like “I am able to replicate the issues you are facing” and some mockable phrases like “We are hoping that this will improve your perception of AMD products and…

Zip-NeRF: Anti-Aliased Grid-Based Neural Radiance Fields
Neural Radiance Field training can be accelerated through the use of grid-based representations in NeRF's learned mapping from spatial coordinates to colors and volumetric density. However, these grid-based approaches lack an explicit understanding of scale and therefore often introduce aliasing, usually in the form…
