The video of my group's latest demo is up!
This one is entirely ray traced via #Vulkan compute shaders. :)

Real-time composition of UI rendered via CEF/Chrome works surprisingly well in my Vulkan engine!

This is what good GPU profiler looks like. Occupancy graph and bottleneck (SOL) graph. In 99% of cases you don't need any numeric data when you have both of these graphs. Slide 58 of my GDC presentation (approved by vendor).

Shader Playground now supports AMD's RGA! As the per the underlying rga.exe, input can be HLSL, GLSL, and SPIR-V Assembly.
You can select which ASIC to target, and you can view disassembly, live register analysis, and CFG.

RenderDoc v1.1 is now out! This release focusses on improved API and OS support, as well as a boatload of bug fixes.

Finally got around to uploading a video of my latest #Vulkan demo!

RGP 1.2 shows driver barriers (including explanation). Awesome feature. Instantly realized that timing queries take 5% of my frame time in development builds (two barriers each, both full L2$ flush). Without timing queries 2% of frame spend waiting in barriers. Much better :)
Released my second #Vulkan demo at AtParty 2018! #demoscene
The party results are now available on pouet:

I'll be uploading a YouTube capture as soon as I get a chance.

Vulkan 1.1.76 spec update is out, featuring VK_KHR_draw_indirect_count (yay! finally! :)). Hopefully driver support will be there soon? I've updated github.com/zeux/volk to the latest version.
