One of the reasons I like PowerDraw is the Software Renderer.
As I see, you can not access to adapter info via

PowerDraw1.AdapterIdentifier
PowerDraw1.AdapterMode

while not in hardware mode.
I' ve working on this and I modified the PowerDraw unit to give also information in software mode (screen resolution, refresh rate, adapter name, adapter description,...)

Maybe you think it's good to add to PowerDraw 3??
This is the lees I could do for your help
