ActiveX DDraw Surface Blt too Slow on Internet Explorer 6

Hi all, I have implemented an ActiveX control for rendering video. I
use DDraw for blitting images from an offscreen surface to a primary
surface. Everything works fine (Blt's are very fast 0-5msecs) when I
test my ActiveX on a dialog application or on Microsoft ActiveX Test
Container. However, when I test the ActiveX on Internet Explorer by
embedding it on an HTML page, the Blt from offscreen to primary
surface takes too much time (45-70 msecs). I log all the error return
cases from DDraw, I don't get any error though.

If anyone has an idea why this could happen, it is more than
appreciated. Thanks.

I'm not a rendering guru, but it could just be that IE6 adds too much
overhead for it to run at full speed. Do you have other programs with
similar resource usage that don't exhibit the slowdown?
