If you're having high resource usage or FPS drops while capturing gameplay with Moments, you can try these solutions.
- Lower the video quality in 'Settings' -> 'Video Quality' -> set video quality to medium
- Lower the FPS in 'Settings' -> 'Video Quality' -> set FPS to 30FPS
- Allow Moments to capture with elevated permissions in 'Settings' -> 'Capture & Sound' -> 'Capture with elevated permissions ON'
