What sort of Metal topics would you like to see me write about? I’ve got ideas, but I’d prefer to maximize interest and usefulness. ∙ Practical physically-based rendering ∙ Raytracing ∙ Shadows ∙ HDR/multipass rendering ∙ MPS image filters ∙ Your suggestion here?

Thinking about it it could be that I copied the 3D data each frame for each instancing-object. But I could be wrong. If you‘re interested I could dig out my thesis and have a look if I find the problems that I could not solve.
Makes sense. I’ve found calculating instance data, as well as computing matrices for skinned animation, to take up the bulk of CPU time in some cases, dominating encoding. At that point, you want some strategy (like a job system) for multithreading, which I haven’t written about.
