Not sure what thing you are talking about -- but some/many opengl progs seem to work with XWin across a local network (using programs on my linux box, and display via Cygwin X). Many of them operate at full speed, but depends on application: > glxspheres Polygons in scene: 62464 libGL error: failed to load driver: swrast *** Visual ID of window: 0x2c6 Context is Indirect OpenGL Renderer: GeForce GTX 1080/PCIe/SSE2 3220.365264 frames/sec - 3593.927634 Mpixels/sec 59.853303 frames/sec - 66.796286 Mpixels/sec 59.854641 frames/sec - 66.797779 Mpixels/sec 43.856578 frames/sec - 48.943941 Mpixels/sec 150.846871 frames/sec - 168.345108 Mpixels/sec 36.137460 frames/sec - 60.207032 Mpixels/sec --- different values were for different window sizes. *** - this failed to load driver is a bogus msg that comes out with any/all programs that use an indirect context...

Anyway, thought I'd chime in. Of note -- glxgears sometimes works but is often frozen upon startup. -l -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
