so _DISPLAYORDER makes the software layer the 1st and the gl layer the 2nd, hence the gl layer shall be ON TOP off the sofware layer.

But _GLRENDER instead says render the gl layer behind the software layer, so what has precedence?

The last called or what?

_GLRENDER is just a fancy _DISPLAYORDER, they modify the same thing. They have this correspondence:

Code: (Select All)

_GLRENDER _BEHIND -> _DISPLAYORDER _GLRENDER, _SOFTWARE, _HARDWARE, _HARDWARE1
_GLRENDER _ONTOP -> _DISPLAYORDER _SOFTWARE, _HARDWARE, _GLRENDER, _HARDWARE1
_GLRENDER _ONLY -> _DISPLAYORDER _GLRENDER

As far as performance goes, the only real one to consider would be `_Software` because the screen image always gets rendered even if its blank (IE. If you're drawing the whole screen with OpenGL, the blank software screen still gets rendered below it first and that wastes some minimal amount of time).

`_Hardware` and `_Hardware1` aren't a huge concern if you're not using them as if there's nothing in the queue to be drawn then that code doesn't do anything. There is no blank 'hardware screen' that always gets drawn as there is with`_Software`.

`_GLRender` also doesn't really matter - if you don't have a `SUB _GL` in your code then that rendering section is empty (and if you do, then presumably you want to be using it).
