I did some testing yesterday evening on Windows and here are my results:
{ Platform: Athlon X2 4200+, 2GB RAM, Windows XP latest patches, NVIDIA
GF7900GT & low-end NVIDIA 6150, 3 screens }
Running runexamples.bat for each threading model
Single-Threaded
===============
osgimpostor (extremely slow)
osgplanets (corrupted image on center & right screens - left screen OK) -
will double check my setup
all other examples perform well
CullDrawThreadPerContext
========================
osgprecipitations (slow)
crashes for:
osgdistortion
osgdepthshadow
osgimpostor
osgprerender
osgprerendercubemap
osgshadowtexture
osgsimulation
DrawThreadPerContext
====================
osgprecipitations (slow)
update processing seems to be out-of-sync
(very fast movements when mouse is used)
No smoke/fire effects visible for:
(probably due to issue above)
osgblendequation
osgmultitexture
crashes for:
osgdistortion
osgdepthshadow
osgimpostor
osgprerender
osgprerendercubemap
osgshadowtexture
osgsimulation
osgpick
osgspheresegment
CullThreadPerCameraDrawThreadPerContext
=======================================
osgprecipitations (slow)
update processing normal but performance generally sluggish on all examples
crashes for:
osgdistortion
osgdepthshadow
osgimpostor
osgprerender
osgprerendercubemap
osgshadowtexture
osgsimulation
osgpick
osgfxbrowser
I will try to look at some of these issues this evening.
André
