Drawing with GDI+ in C#

So I've been writing an online role-playing-real-time-strategy game (think of the SNES Final Fantasies having a love-child with World Of Warcraft) and it's actually coming along very well. I decided I didn't want to use any third-party code (such as XNA) and I was too lazy to learn directx, so that left me with GDI+.

This works just fine, except I can't find a way to get GDI+ to use video RAM; it only uses system memory which makes it quite slow on older machines.

Does anyone know how to force VRAM usage or any other pointers to this problem?

To use VRAM, you have to use a graphics package, there is no way around it. DirectX or OpenGL is the only way to do it.
