Show HN: Avoid smooth spinners, use low-FPS spinners
7 hours ago
- Low-FPS spinners reduce CPU/GPU usage from ~50% to ~3-8% on typical laptops, decreasing battery drain, heat, fan noise, and app slowdowns.
- The page uses no JavaScript and provides public-domain code for copying and implementing these spinners.
- A comparison table shows GPU usage for various spinner designs in HTML vs SVG, with SVG generally performing better due to fewer independent GPU layers.
- Measurements were taken using Chromium's Task Manager on an i7-7500U laptop, with individual designs displayed one at a time.
