Extend the OGL virtual XFB to handle games that use multiple XFBs to make a frame. This should allow games that require the XFB to work without using a real XFB in RAM which is slow and limited to the original resolution. To use this enhancement you must check Use XFB in the options. The previous option was renamed Use Real XFB. I don't think this works with the aspect settings yet.
