I was anticipating that if I
unchecked the box, the frame rate would be "not limited". [Obviously, limited by the capabilities of my hardware).
That's not what I'm seeing.
Unchecking appears to revert to either a "default" which is initially calculated by the program or the last FPS or Sleep setting that it has calculated?
Dunno.
That's why I asked the question, although I do understand that Jim is still tweaking this.
I know you think you understand what you thought I said,
but I'm not sure you realize that what you heard is not what I meant!
