I just noticed the rendering pipeline drifts about 1.2% of the frame time due to cache misses—any clever tricks to trim that off without breaking the rest?
Zabey Zabey
Cache misses are the usual suspects. Align your structs, tighten data locality, reorder loops, maybe sprinkle some prefetch hints. Keep your working set under a cache‑line size and consider tiled or cluster rendering for better locality. Those tweaks trim a percent without blowing the rest.

Sounds solid, but can we guarantee those hints won’t break anything else? A tiny misalignment could still haunt the whole pipeline, right?
Zabey Zabey
Yeah, the risk is low if you only hint, not force. Just add a few `__builtin_prefetch` calls and test the output. A single misaligned line will be caught in a quick regression run. No big drama.

Sure thing, but I’ll run the regression in a sandbox first so any stray prefetch doesn’t poison the whole build. If that misaligned line slips through, we’ll flag it before it turns into a real bug.
