I get 30 FPS when clicking on the tiles, and the FPS drops to about 20 FPS when the DXG logo gets really large. 600Mhz Pentium 3, 4MB ATI Rage Pro Turbo card. Also, the particles from the mouse only used the alpha from the color compoment, not from the texture. I do know my video card is capable of combining both because I've used it in a particle system. You might want to check your alpha render states.
