%description
Primus is a shared library that provides OpenGL and GLX APIs and 
implements low-overhead local-only client-side OpenGL offloading via GLX 
forking, similar to VirtualGL. It intercepts GLX calls and redirects GL 
rendering to a secondary X display, presumably driven by a faster GPU. 
On swapping buffers, rendered contents are read back using a PBO and 
copied onto the drawable it was supposed to be rendered on in the first 
place.
