profiling on the problematic machine showed, that we spend practically no time
within the presentation or vcl, but ~2/3 in BitBlt and 1/3 in
CreateCompatibleBitmap. The BitBlt is essentially the drawing whereas the
CreateCompatibleBitmap seems to be from drawing a BitmapEx with Alpha channel
(which is probably trivial all none transparent since there is no transparency
in the game here). Exchanging the DrawBitmapEx by DrawBitmap did not improve the
situation much, we now spent practically all of the time in BitBlt - which was
the expected result.
Also the situation improved dramatically when reducing the resolution from
1024x768 to 800x600. My hypothesis is that we run into a resource problem; that
at lower resolution all the blits happen on the graphics adapter whereas at
higher resolution main memory gets involved.
