Thanks, this is exactly the info I needed.
The ATI driver probably doesn't swap the WGL_SWAP_METHOD_ARB control,
this may or may not be an issue, perhaps Andreas can comment. If its
not an issue then we can probably change the warning into a info.
My guess is that the crash is probably unrelated to the above warning,
the fact you you dual core and have one screen means that
osgViewer::Viewer should be choosing to run using the
DrawThreadPerContext threading model. This threading model double
buffers the rendering backend, allow update and cull to run in
parallel to draw.
The parallism of DrawThreadPerContext also requires the scene graph to
be set up so any changing Drawables and StateSet's are protected by
setting DataVariance to STATIC. I will look at the example and do
lots of testing on to see if I can recreate the crash, once I have I
can test fixes for it.
If you could override the threading model selection so that it is
SingleThreaded (as per my previous email) then we'll be able to know
whether my hunch above is correct.
Robert.
