GDI+ is not a speed demon by any means. Any serious image manipulation usually has to go into the native side of things (pInvoke calls and/or manipulation via a pointer obtained by calling LockBits.)

Have you looked into XNA/DirectX/OpenGL?. These are frameworks designed for game development and will be orders of magnitude more efficient and flexible than using a UI framework like WinForms or WPF. The libraries all offer C# bindings.

You could pInvoke into native code, using functions like BitBlt, but there is overhead associated with crossing the managed code boundary as well.
