Pass -interval 1
to glxgears, and it should work as you expect. VGL_REFRESHRATE controls VGL's implementation of the GLX swap interval extensions, which allow applications to specify that glXSwapBuffers() should wait for the specified number of vertical refreshes before returning. The application has to enable this functionality, though, and in glxgears, the -interval switch does that. > On Feb 17, 2014, at 7:16 PM, Dyweni - VirtualGL-Users > <t7nhgfds7...@dyweni.com> wrote: > > Hi, > > I'm finally getting around to testing the new VGL_REFRESHRATE option > VirtualGL 2.3.3.
