you know them: duck3d, blood, shadow warrior. do they have timedemo feature like doom?
i know that duck3d has a "dnrate" code which displays current framerate, but can it run a timedemo after all? and what about blood and shadow warrior?

last of all, are there any 2.5d games/benchmarks(not the 3d rendering like quake) that are makes heavy use of fpu instead of integer rendering? is there a fpu equivalent of pcpbench?
