Sure, hit the loop, measure the tick, and pull the latency out of the loop before it pulls you in. First, instrument the code with a high‑resolution timer, like std::chrono::high_resolution_clock, and log every branch. Drop the “if” that checks a flag twice per frame; it costs 0.8 ms. Use cache‑friendly data layouts, unroll inner loops, and lock‑step the GPU dispatch with the CPU tick so you’re not waiting on a fence. Then, profile the memory bus with a tool like Intel VTune or perf; if you see cache misses, you’ve got your micro‑lag. Finally, keep a spreadsheet with latency vs. each tweak so you can see the trade‑off curve. That’s the rubber‑band way: stretch the code, snap the loop, re‑configure until you hit the sweet spot.
