I am going to go out on a limb and guess we're going to see a crapload of reports of "performance regression" due to reduced glxgears frame rates. Mayhaps this could be headed off by changing glxgears output a bit? Something like: $ glxgears Failed to initialize TTM buffer manager. Falling back to classic. 300 frames in 5.0 seconds = 100.0% synchronized 299 frames in 5.0 seconds = 99.93% synchronized 300 frames in 5.0 seconds = 100.0% synchronized Bryce _______________________________________________ xorg mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/xorg
