Ronald,
My suspicion is that Background images or fills are not passed through the 3D API so
3D hardware acceleration is not going to help here. [I hope I'm proved wrong on this].
If the texture image is large 10 FPS seems about right. I suspect the Background image
is drawn into the frame using 2D APIs first and then all geometry is rendered into the
frame on top using 3D APIs.
You could try the trick I described a few days ago of mapping a texture image onto a
sphere and using that as 3D geometry. That will definitely go through the 3D API and
may prove quicker for you. It also gets around the problem of resizing the texture
image when the user resizes the window.
Sincerely,
Daniel Selman
