disclaimer: sorry about my voice, but this was recorded during a 24 hour food poisoning marathon and my throat was really raw and scratchy

A medium length video about the pain of mixing scalars and vectors in computation. I’ll show examples on all three CPUs you will encounter as a game developer: PowerPC, SPU, ARM (although technically there are some people still doing PS2 MIPS, VFPU, or maybe even 68000). I’ll explain how particularities of each architecture make it harder (or easier) to do things like horizontal add and vector insert, and point out where the performance problems are. I will also open with one of the illest demos I ever heard on Stretch and Bobbito
