@newincpp Nevermind, I guess they aren't consistent about it. Thanks Vulkan!

[Andy Robbins @miniciv]

@newincpp Checks out. Byte 0 for your CPU endianness would be where 0xRR is. You read the hex value right to left, but the Vulkan format left to right.

I have shared it in the past but it is worth re-sharing this great collection of resources on GPU optimisation: https://t.co/iy6bFN56rO

If you want to learn how to implement a simple shader printf in HLSL 2021 and D3D12, then I've got a new blog post for you: https://t.co/1oULzlk48Q

A classic book on radiosity and image synthesis was just freed up by the authors, making two that have recently become available: https://t.co/Kzrh8O4GSi

“Low-level thinking in high-level shading languages” is in my top 3 most influential presentations, one that changed the way I think about shader programming. 2023 was the 10th anniversary so I tried a quick refresh and discussed developments since. https://t.co/fFmymkfe9R

Great explainer of occupancy, also includes some new info I haven't seen elsewhere, eg the 16 waves max occupancy for RDNA2/3 (compared to RDNA's 20) and the inter-wave barrier needed for threadgroup with 2+ waves and how it affects occupancy https://t.co/3IlkPTvt6F

Here is a new blog post of mine about fibers.
Hopefully, it could be helpful to someone who is interested in learning the topic.

@JeremySCook @PCBWayOfficial @digikey Thank you Jeremy! Learning a bit more every day 🙂

I’ve written a small library that provides an assert-like macro in HLSL shaders that triggers a GPU memory page fault. Together with Radeon GPU Detective, it may be useful for debugging. https://t.co/pMJY14v19s

I never knew how much I needed this!

The @AMDRadeon Developer Tool Suite has a new member: Radeon #GPU Detective (RGD) 🕵️

RGD is a tool for post-mortem analysis of GPU crashes so you can:
🎆 Capture and analyze crash dumps
🎆 Narrow down the root cause of a crash

Take a look now! #D3D12

[Adam Sawicki @Reg__]

The tool that was so much needed finally appeared! Radeon GPU Detective can capture and analyze GPU crashes / TDRs. I am happy and proud to be part of this project.
