You can change state to modify appearance, but if you mean modifying
appearance based on time to render it would require fine grained
measurements which would in turn lower performance. It would be possible
within limits and you could possibly use your own instruments calls in
callbacks but even that would affect state sorting.

In short this is fairly hard to do, so, can you be more specific?

Cheers,Angus.

For years now, whenever NT has been proven to have some debilitating
weakness we've heard from MS advocates that NT would catch up, there was
just an incredible faith in this OS and Microsoft's ability to somehow
get there. With the recent results of the Linux vs NT serving benchmark
that same attitude can be seen in the Linux community. The Linux folks
aren't too worried, "Sure the single threaded IP stack was slow but
it'll be fixed in the next release.", it's eerily familiar but I have
confidence in the Linux community's ability to remedy problems and I
don't groan in pain as I used to when Microsoft made similar claims.
