Tried it on a couple more machines and all the same issue. This issue has
been there since post OSG1.2. Have a look at the attached screenshot.

Happens in debug and release.

Did do the Cmake release compile but the /O2 option didn't get set in the
vs project by Cmake (running VS2003 7). Had to add it manually. Now have
comparable fps as OSG12.
