First, thank for your reply.
No, I am not using 3d functions, it is just a simple demo to learn the basics (I render only with DrawImage) and test the performance. Maybe I used a wrong term, I am using the standard transparency feature of DrawImage (a single rgb value masked, like documented in MaskImage).
Flip 0 is a bit better on the ATI RADEON 9100 machine, but still very slow (around 26 fps with parallax background, 42 with no background).
My fps code is very simple and, anycase, you can see the difference even without reading fps because it is silky smooth on the Geforce 4 MX Pentium III machine.
