* Hardware acceleration @ 2013-03-29 16:11 Thiago Padilha 2013-03-30 4:16 ` richardvoigt 0 siblings, 1 reply; 3+ messages in thread From: Thiago Padilha @ 2013-03-29 16:11 UTC (permalink / raw) To: cygwin-xfree Hi I'm testing cygwin hardware acceleration using the instructions found here: http://cygwin.com/xfree/docs/ug/using-aiglx.html When running the the default options(which implies -wgl) I can see my graphics card (Intel HD graphics 3000) when running glxinfo | grep OpenGL If I start the server with -nowgl, I see the software renderer. The problem is that I see absolutely no difference between the two when running the 'glxgears' program: It starts fine and stays like that for 2-3 seconds, then I start to see some flickering(the gears seem to be constantly "struggling to rotate), but the fps displayed in the terminal is not affected(I get a constant average of 1500fps), just the rendering gets strange. Perhaps I'm missing something(some other lib that needs to be installed)? -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://x.cygwin.com/docs/ FAQ: http://x.cygwin.com/docs/faq/ ^ permalink raw reply [flat|nested] 3+ messages in thread

What you're seeing is a result of aliasing, which is an interaction between the framerate of the software and the refresh rate of the display. -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://x.cygwin.com/docs/ FAQ: http://x.cygwin.com/docs/faq/ ^ permalink raw reply [flat|nested] 3+ messages in thread

Perhaps you have some hint on how I can configure aliasing correctly or fix this issue?
