Well, you'll have to write image data onto TAGFImage either using Pixels property or locking/unlocking the specified texture. Still, I wouldn't recommend it... it's just a waste of video memory. For reference, how big tiles are you rendering? What texture format and video mode do you use? I'm sure you're having a performance hit somewhere... for our project we used to render 32x32 tiles and it ran pretty fast... what's the FPS of Water example supplied with PowerDraw?
