Hi all,
I am testing trunk OSG on older devices. I've noticed that osgTerrain
crashes on ATI 9550/X1050 Series driver version 8.561 on WinXP. To make it
run I had to comment out geometry->setVertexBufferObjects(true) in
osgTerrain\GeometryTechnique.cpp:668. Further investigations revealed the
same problem when simple osg file with useVertexBufferObjects TRUE is
loaded. The osgviewer crashes and following stack trace is generated:
atioglxx.dll!691ae750()

I suspect lack of FBO support on this particular card. I've tried to locate
spot where FBO support is tested but didn't find anything. Has anyone had
similar problems on older cards?
Regards,
Maciej
