Hi, The osgprerendercubemap example runs really slow with the latest nVidia drivers. I tested it out on 3 machines with osg 1.0, 1.1, and 1.2, and they all exhibit the same problem. I reverted to an older version of the nVidia drivers and the example runs smoothly again.
I tracked down the cause of the slowdown to a single call. The following line in osg::FrameBufferObject::apply is causing the problem: ext->glBindFramebufferEXT(GL_FRAMEBUFFER_EXT, fboID); Here's the weird thing about the problem. If I have an osg application already running when I run the osgprerendercubemap example, then it runs smoothly. As soon as I exit the other osg application, the osgprerendercubemap example will run slow again. This makes me think that this might be an issue with the nVidia drivers, and not OSG. Can anybody else running the latest nVidia drivers for Windows XP verify this problem? -Farshid _______________________________________________ osg-users mailing list [email protected] http://openscenegraph.net/mailman/listinfo/osg-users http://www.openscenegraph.org/
