With OpenGL you get quite a good performance boost, along with fast
alpha blending, scaling and rotating. The Framerate might double or
tripple in OpenGL. For a 2D OpenGL game have a look at:

For a Libraries which support 2D OpenGL directly you can have a look
at:
 
 * ClanLib 
    http://www.clanlib.org

 * SphriteLib (a simple but usefull Spritehandling library ontop of ClanLib)
