Hmmm. I wonder if I went back to similar drivers here and tried it... I
might try that early next week (I have a deadli

Of course I am interested. :-) Thanks for testing. Seems like the more
recent nVidia drivers give problems when switching threading modes, and
older ones are OK. Unfortunately I am on Vista so using ol
Hi J-S,
I was on vactions. But if you are still interested I did the test you
wanted. I have added ThreadingHandler to shadow example. Pressing m does not
crash the program but freezes shadow map. Shadow map is no longer refreshed.
I did the same quick test with prerender example and results are s
btw I seem to see a rendering artifact: the effect is that a large poly
seems to be above the scene, resulting in a rotating shadow. As far as I
remember this was not here in version 2.2.0... see the attached image.

You can just add
viewer.addEventHandler( new osgViewer::ThreadingHandler() );
to the osgshadow example (around where the other handlers are added) and
comment this line:
Hi J-S,
Do you have an example which I can try. Then I can give it a try here,
on a couple of machines.

Hi all,
So since no one has replied, I gather no one else has had any problems
changing the threading mode when shadows are enabled (for example, in
the osgshadow example)?

Hello,
I was wondering if there were any known problems related to using
osgShadow::ShadowMap and changing the threading mode.
In the osgshadow example (SVN), if I change the threading mode (I added
a threading handler to it) my graphics driver crashes.
