[Flightgear-devel] plib OSG Performance Linux and Windows

[Olaf F. <fg...@of...>]

Hi,

I tried to shed light into the OSG/plib performance issue and why it 
hits Windows users.

I installed Fedora Core 6 (fought with fglrx to get direct rendering to 
work ;-) and compiled FlightGear with the same sources I use on Windows 
XP. Both OSG and Plib.

* OSG has quite the same performance on Linux and Windows. (this seems 
reasonable)
* OSG seems to have the comparable performance as Plib on Linux.
* Plib is a lot faster on Windows.

So the interesting question is: Why is plib significantly faster on 
Windows?

PS: Now I remembered a fact some months ago:  FlightGear on Windows was 
a significantly faster than on Linux on my laptop.... now I see that 
performance was guided by plib.
