Hi, I have on win (msvc express, with Olafs easy to use project files) on a P4M 2,2Ghz 1GB GeForce FX Go 5600 about half the frame rate with osg than with plib. The frame rate is so low (~10fps), that fg is not flyable (and without the plib branch it would be not possible, to check/improve FDMs), and that (if still persistent, when the plib branch is not any longer supported) would kick me out of the project. Plib shows with more graphics features (shadows) a much higher framerate. My opinion is, that we first have to find, where the performance get lost and than to think, where we can make use of things like multi core architectures (to fix 50% performance loss with a second core is not the best way ;-( ) My feeling is, that it will be a long stony way to get fg-osg to the same performance (on most systems) than fg-plib.
