Thank you all for your support^^
If you are looking for details on what the quality sliders do, you can check out Unreal documentation.
I will see if I can find something for this, but no promises.
Is it only the ambient? Or does it apply to music, effect and voice sound channels too? It would be odd of only one of them did not work.

I had some feedback regarding multi monitor support. I have added the ability to move menu bar so it can be put out of the way from a bezel.
