- Use simple scroll effects and fewer animations (Nova Settings → Look & feel → Animation speed).
- Use 4x4 or 4x5 grids on low-res screens to reduce redraw cost.
- Avoid heavy live wallpapers; use static PNG/JPEG.
- Limit widgets (each widget consumes RAM); prefer 1–2 small widgets.
- If lag appears, clear Nova cache: Settings → Apps → Nova Launcher → Storage → Clear cache, then reboot.
