summary
Global web usage hits about 60% connected and maintaining 60 fps gives a 16.6 ms budget per frame, shrinking to ~11 ms at 90 Hz and ~8 ms at 120 Hz. Practical fixes shown are offloading heavy work to WebWorker with Comlink to run reducers or long sorts without blocking the UI, compiling hot code to AssemblyScript -> WebAssembly to encode video in‑browser, and using CSS Paint / Houdini worklets for complex rendering like animated backgrounds or barcode generation while animations remain smooth.
