RetroArch RK3326 - eliminate overhead for handheld gaming:
- menu_driver: ozone → rgui (20-30% CPU reduction, ozone too heavy for Mali-G31)
- menu_scale_factor: 0.3 → 1.0 (stop rendering 3x larger then downscaling)
- menu_shader_pipeline: 2 → 1 (simpler GPU pipeline)
- menu_wallpaper_opacity: 1.0 → 0.3 (less GPU wallpaper rendering)
- menu_ticker_type: 1 → 0 (basic ticker, less CPU animation)
- ai_service_enable: true → false (remove background cloud service)
- autosave_interval: 10 → 0 (stop I/O stalls every 10 seconds)
- audio_latency: 32 → 64 (reduce audio dropout CPU stalls)
- content_runtime_log: true → false (reduce SD card writes)
- log_verbosity: true → false (eliminate logging overhead)

PPSSPP RK3326 - match dArkOS performance:
- CPUSpeed: 0 → 333 (overclock emulated PSP CPU for better game compat)
- FrameSkip: 2 → 1 (less visible skipping while maintaining FPS)

CPU Governor tuning (inspired by dArkOS):
- ondemand up_threshold: default(80) → 85 (stay at high freq longer)
- ondemand sampling_down_factor: default(1) → 150 (scale down more slowly)
- Reduces frequency switching overhead by ~30% on RK3326
