Playing really well! CK2 patchset: ------------- Beryl interractivity almost totally unresponsive... In fact mouse movement was near-impossible to control. - window movement totally impossible - Cube rotation still possible using mouse scroll although there was no animation at all Amarok MP3 music: - Same as CFS, no skips at all. Playing really well! I'll quote Martin on the Ck mailing list: > According to Ingo most of the interactivity issues should be fixed by now. > Still I do not see how that translates to "CFS was generally better". Well, here you go: For having followed RSDL since version 0.28 I'd say Con did a really great job but for me CFS v16 now, on my hardware, offers better interactivity using beryl window manager. - vin - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
