RW Enhancer 2 is quite well optimized now with all optimization updates I have made. There still room for performance improvements but there is a solid base now. RW Enhancer 2 is using CPU cores quite well for the audio engine for example and other specific tasks.
Important fixes still need to be made during January and then i will be able to start the work on more bigger features
