 Hi Donn,

 We went across this week and are getting the same. About 40% drop in
 framerate with certain paged data sets.

Curious.  2.x and 1.2 are still fundamentally the same scene graph.
CullVisitor and DatabasePager changed little in the 1.2 to 2.0 period.
 Changes to CullVisitor principally lie in the handling of RTT
Camera's.

Recently I checked in a range of changes to DatabasePager to manage
threading better under Windows, and to add compile context support,
but neither of these I'd expect to see an impact on cull.

In the SVN version there is now default use of mutexes in the
rendering backend which has slowed the cull traversal a bit, this code
is still experimental and subject to further changes.

[Mielcarek, Donn]

Tried it both ways. I've found running in
debug mode on Linux hardly affects the
frame rate at all - on Windows it
takes a big hit.

Hi Donn,

Could it be that you've haven't built the OSG as release build?  If
you run cmake . stright it'll won't by default select the release
build.  If you run the ./configure script it will select the release
build as it does:

cmake . -DCMAKE_BUILD_TYPE=Release
