 Suspend/resume uses the existing LÖVE focus/visibility lifecycle: input is reset on focus loss and the game resumes when the window becomes visible again. Exact power-button behavior remains firmware-dependent; hardware validation has been performed on the TrimUI Brick, not every SBC or H700 device.
 
+## Power and Performance Tuning
+
+The handheld build applies several optimizations to reduce power draw and ensure smooth 60 FPS frame pacing on low-power ARM SoCs:
+
+- **KMSDRM / EGL Vsync Fix**: Handheld builds disable driver vsync (`vsync = 0`) to prevent GPU driver busy-wait spinloops in `eglSwapBuffers`, allowing `nanosleep()` and dropping idle CPU usage from ~25% to ~4%.
+- **Idle Render Governor**: Drops presentation rate when a static screen (menus, text dialogs, stationary scenes) receives no input, cutting compositing work ~6x while preserving full 60 Hz game and audio clocks. Any button press restores full framerate immediately.
+- **Sample Rate Scaling**: Audio synthesis is tuned to 22.05 kHz by default (`POKEPORT_AUDIO_RATE=22050`), halving synthesis CPU overhead on Cortex-A53 cores with no audible quality loss on handheld speakers.
+- **Dynamic CPU Governor**: Defaults to `schedutil` instead of pinning `performance` on all cores, reducing thermals and extending battery life.
+
+Environment variables for fine-tuning (configured in `gen1recomp-sbc.sh`):
+
+| Variable | Default | Description |
+| --- | --- | --- |
+| `POKEPORT_IDLE_AFTER` | `10` | Seconds without input before an idle screen drops presentation rate |
+| `POKEPORT_IDLE_FPS` | `6` | Framerate while idle |
+| `POKEPORT_AUDIO_RATE` | `22050` | Chip-synth sample rate (set to `44100` for full rate) |
+| `POKEPORT_CPU_GOVERNOR` | `schedutil` | CPU scaling governor (`schedutil`, `performance`, `ondemand`) |
+
+
 ## Building
 
 Release workflows build this automatically. Standalone builds resolve the latest published Gen1Recomp release by default:
