I'm using a pocketPC2003 with a wince4.1 system.
And I'm using a small MFC program to test the library. I find it is very much slower than the programs in Window2000 system.
I use glDrawArray() function to draw some lines, the drawing speed is about the same as that of GDI functions( e.g. PolyLine() ).
But in Windows2000, I wrote the same program drawing some lines using openGL, and the drawing speed is very much faster than Windows GDI function.
I don't know why it can't be so fast in wince.
Do I need some other hardware of graphic driver support( e.g. directx ) ?
What should I do to make it as fast as it could?
