DirectX vs GDI+ for drawing maps in GIS

Question

Hello all,

Just a quick question. I've been wrestling with getting GDI+ to perform well when drawing maps and editing. moving polygons and shapes within maps. The performance just lags. So I would like to know whether it would be worth while to get into DirectX for doing this. I know I can use DirectX to access the hardware directly, so this might be a good choice.

Thanks for your help in advance
