Performance issues?
- Lower the Flow Scale setting for better performance

- Provides an easy-to-use interface to configure frame generation settings:
- FPS Multiplier: Choose 2x, 3x, or 4x frame generation
- Flow Scale: Adjust motion estimation quality vs performance
- Performance Mode: Use lighter processing for better performance
- HDR Mode: Enable for HDR-compatible games
