Framerate Issues - using Radeon 9550 (bottom end DX9  card)

Strangely, my DX apps run at 49 to 72 fps, and i cant tell what makes them run at these rates. But this is clearly nowhere near possible, upward of 700 fps for a simple scene. Looking in Control Panel > Direct X, i see that i've selected 'Use retail version of direct 3D', instead of 'Use Debug version of direct 3D'. So why no speed ? Also, i can compile the microsoft sample directX empty project and it runs at 760 fps.

PS. When's part IV coming online, i think we're ready for it. Smiley
