Hi Robert,
wouldn't it be a better approach to give the user the option to change
such a setting for their application?
But thanks for pointing out the subclassing option, that's what I'll go
for! Still it took me half a day to track down what was going on. (I
didn't suspect OSG in the beginning at all, and since there are quite a
few dependencies in our application, it took me considerable time to
track it down.) I think that's a sufficient reason to at least mention
it in the documentation, better yet make it not default but optional
behavior that the user can set?
Christoph

This is, bizarrely, by design.
In single-threaded mode, OpenSceneGraph silently sets CPU affinity to a single
core by default. Personally I think this is incredibly obtrusive on the
programmer, and the reasons for this being default behaviour are terrible, but
it is what it is.
Affinity is set by default because the it will provide the best
performance for majority of OSG applications. This might be a
"terrible" reason for you, but the OSG development is motivated not by
just focusing on one class of users needs or preferences, default
settings we try to do the best for most OSG applications.
Please remember, The OSG is extensible, if you don't like default
behaviour in most cases you can adapt the it. In the case of threading
ViewerBase::setUpThreading() and startThreading() are both virtual and
as such are meant for the purpose of specializing them in subclasses
from ViewerBase i.e. Viewer+CompositeVIewer and for users then to
subclass from these if they wish.
Robert.
