Honestly, forget about AI tools. The trifecta of power tools for game engine development is RenderDoc, Superluminal and Live++. Hands down the most bang for your buck you can ever get and RenderDoc in particular is criminally underpriced.

I wrote a blog article about D3D12 resource states.
It explains the rules around state promotion/decay and how that means a resource can be used on multiple queues at the same time (even if one queue is writing!)

I have another take on “Vibe Coding”, and it doesn’t involve gen AI:
Spend time coding on a project you enjoy, following a coding methodology and style that reflects you, experimenting on things you like, without overbearing process.
That, is vibe.

I'm almost done writing my STL replacement, or at least I have enough to replace almost all std:: uses in Asset Cooker.
All that's missing is Mutex, Semaphore and some specific Atomic specializations for pointers/enums. A few evenings of work?
After that I guess I'll make the github repo public 😶🌫️

RESTIR is one of those moments in computer graphics where a method is too useful to ignore, but too complex to fit in a textbook paragraph - and with time, the explanation simplifies and it becomes canon. This course by Chris Wyman is a huge effort to explain and simplify
