No further comments needed, it's **very** good.

I've seen some of his videos in the past, but I missed this one. Glad I saw it.

Nanite Tessellation Nanite Tessellation, aka Nanite Dynamic Tessellation, aka Nanite Dynamic Displacement was the next major feature I worked on after Nanite it...

I'm finally writing up how Nanite Tessellation works. The first few blogs posts are up. More will be coming.

This post shows how to get different constants for the R2 low discrepancy sampling sequence which have the same properties, but are smaller valued, so behave better in floating point at high sample counts.

I spend 1.5 years doing this. Full rewrite last summer and another partial rewrite last month. As Hemingway said: "First draft of everything is always shit".

From profiling to kernel patch: the journey to an eBPF performance fix | Ritesh Oedayrajsingh Varma A story about how an innocent profiling session led to a change to the Linux kernel that makes eBPF map-in-map updates much faster.

New article! What do you do when profiling your code shows the slowdown isn't in your code, but deep in the kernel? Why, you grab the kernel source and go spelunking.

Ten Years of D3D12 For those of us that have been using it from the start, it can be hard to believe that Direct3D 12 has been around for nearly ten years now. Windows 10 was released on July 29th 2015, and D3D12 has be...

I've got a new blog post for all of you fine folks! It runs through the additions to D3D12 since it was released, and finishes up with some of the things that have changed for me personally in my code.

(And yes it's really been 10 years 👴).
