New OpenGL Extension 'GL_NVX_linked_gpu_multicast'
http://devblogs.nvidia.com/parallelforall/vr-sli-accelerating-opengl-virtual-reality-multi-gpu-rendering/ I was reading about this new GL extension from Nvidia and was wondering what potential implications it could have for OpenGL wrappers/3D vision. [quote="Parallel For All"]Autodesk VRED has successfully integrated NVIDIA’s new multicast extension into its stereo rendering code used for HMDs like the Oculus Rift and the HTC Vive, achieving a 1.7x speedup (see Figure 1). The multicast extension [b]also helps Autodesk VRED with rendering for stereo displays or projectors, with nearly a 2x speedup[/b]... With the OpenGL multicast extension, it’s possible to upload the same scene to two different GPUs and render it from two different viewpoints with a single OpenGL rendering stream. This distributes the rendering workload across two GPUs and eliminates the CPU overhead of sending the rendering commands twice, providing a simple way to achieve substantial speedup [/quote] :-)
