FullScreen Mouse cursor


I have some quick question. I’m trying to create a mouse cursor under fullscreen mode of OpenGL. I’ve seen that many games ( usually MMO’s ) have a OS cursor system in fullscreen mode of the game - thats why it hase independedt thread of mouse rendering and it has all features like acceleration, speed set up in system. Another advantage is that fps doesnt affect of the refreshing mouse cursor.

Is it possible ( and how , if not regular API ) to create a fullscreen OS mouse cursor. ( tried to use ShowCursor, LoadCursor etc, but it seems not to work propertly ).

Thatnks for any answers.
