Hi, I have a Quadro FX 1700 with the latest 64-bit Nvidia drivers on Windows XP/64. My app is a 64-bit Windows application.
For testing I am creating a single osg::geometry with probably about 3.2 million QUAD primitives , using quadPrims_=new osg::DrawElementsUInt(osg::PrimitiveSet::QUADS); I am not using VBO's. Once the osg scene graph is created, and the render phase begins. I see the border of my screen "flash" black twice and then my application is in "la-la" land, with a blank 3D window and needs to be killed. The app is using about 2G of memory but I have 9G free. More info... - osg does not report any errors - if I turn off the nVidia driver and switch to the default "software" OpenGL driver, the geometry renders fine. - If I take a geometry of a similar size or even much bigger, but break it up into multiple geometries so that each DrawElementsUInt is "smaller" there are no problems. I am not aware of any specific limitations on glDrawElements that says the number of elements must be < "some number". The reference guide says there may be performance problems with numbers > GL_MAX_ELEMENTS_VERTICES/INDICES but it is not a hard limit. Any one experienced similar problems?
