You click the download button, extract the zip file and run the program.
Please close your music player before running it, then it will alert you as to whether to reopen your player after the optimizations are done. Say yes to this and browse to the folder where the player is installed and select your player in the pop up window. Select the
Purist level of optimizations. Then see if there is any improvement. It claims to improve clock resolution and reduce latency, and I am hearing a smoother and more detailed sound. Like pillows of sound flowing into my ear lol.
You can undo all this by just opening task manager and ending the task (Fidelizer). Let me know if you are trying it
