In addition to the
difference in frame rate, OSG also stutters, while plib is commendably smooth.
I've tried both
executables generated here using MSVC8, and Fred's pre-cooked binaries. So far
as I can see the results are identical. I've profiled both OSG and plib - for
anyone interested, some of the results are here:
While I am no expert in profiling code, the results
seem to me to show that we are getting stuck in the bowels of OSG somewhere,
while plib is well-ordered, with no particular cpu-hog, which is pretty much
what the above table indicates.
My principle concern is that there appears
to be very little headroom for future developments in OSG for shadows, or 3d
clouds, or landing lights, on what is a not-very-old and pretty capable
machine. I would be grateful if some Windows user(s)
could confirm at least the shape of these comparative
results. I understand that Linux users get much better results than these.
We might be getting towards the point when Windows users are stuck with plib
(and that's not all bad) while Linux users get to play with all the new goodies.
We might be drifting away from our cross platform
Luckily the new card wasn't terribly expensive
otherwise I would be quite p'd off
