[osg-users] Supporting multiple frame rates

Hello, We currently have an OSG based application which renders at 30-60+ fps on our development hardware with discrete gpus. Unfortunately we have to be able to deploy on a wide range of hardware including stuff that is significantly less capable (Intel GPUs, etc). On some of these slower

Re: [osg-users] Supporting multiple frame rates

Hi Brad, I'm afraid decoupling the rendering of two parts of graphics window so that they can run at their own frame rate won't be a straight forward task, and well off the standard viewer path used by the vast majority of the community. You are infact the first I recall wanting to do exactly

Re: [osg-users] Supporting multiple frame rates

Hi Brad, I haven't tried this myself, but it might work. Create a separate context/thread that renders the scene to a texture. Once it finishes rendering, use the NV_copy_image extension ( http://developer.download.nvidia.com/opengl/specs/GL_NV_copy_image.txt) to copy the image into the main
