We put time-hog slugs in the code that reduce your machine to a =
minimum-spec
one in normal builds. Solves that problem quite nicely. It's fairly
approximate, but then so is anything on a PC :-)

The gotcha is that the nature of the graphics code changes radically =
with
timing slugs, because the whole GPU/CPU parallelism thing is completely
different. But then graphics coders have their own huge nightmare with
different graphics cards and so on, so you can probably trust them not =
to go
bezerk with stuff if they have to make it run on a Voodoo1 or whatever.
