FreeBSD support is a bit tricky, as I don't have a full configuration to test. I can test the build and install using a virtual machine, but I can't actually run VirtualGL in it, so there may be run-time problems. It is on my list of things to do to at least try to make vglserver_config work in that environment, however. > Functional with following problems until svn rev 4812 (rev 4813 seems break) How did 4813 break it? 4813 was simply a removal of dead code, almost all of which was enclosed in #ifdef SUNOGL or #ifdef sparc statements. I just re-reviewed that patch and didn't see any problems. > The bottleneck is at readback, and the poor performance > ~9.3Mpixels/sec is only capable of running apps at 640x480x30fps! > When doing readpixels benchmark from mesa-demo (also in attached > typescript), I found that there maybe have room of VirtualGL to > optimize, as vgl's readback speed seems stuck to the 10x10 in > mesa-demo's readpixels benchmark, which give better results on larger > reads. I doubt that this is an optimization issue. I mean, how can you really optimize a single call to glReadPixels()? Have you tried using VirtualGL's PBO readback support? That may be faster. > 3.
