Hi, Actually i dont think it is about hardware or driver because i did a project similar to this with this hardware and it is still working on my computer. it returns true on "isVertexBufferObjectSupported()" but this project was made in like osg ~1.6. The function on Geometry was "virtual void drawImplementation(State& state) const;" on osg1.6 but now it is "virtual void drawImplementation(RenderInfo& renderInfo) const;" on 2.8
so do you think there could be other reasons?
