MSEgui has an experimental OpenGL backend. OpenGL is not well-suited to 
support 2D GUIs IMO. Because of the many different versions and 
implementations, all with different extensions, limitations and bugs, working 
with OpenGL is a difficult task.
MSEgui uses hardware acceleration if available. A framework for animations 
with a central frame tick and the like is planned, although performance of 
simple hardware accelerated canvas drawing is not bad, see for example:
The project is here:
(needs MSEide+MSEgui git master version).

The code:
procedure tmainfo.childmouseeventexe(const sender: twidget;
                                   var ainfo: mouseeventinfoty);
The whole rest are design time property settings only.

AFAIK FireMonkey has no good performance.
