Comment 75 for bug 416073

It seems that in the current KUbuntu 12.04 beta the graphical performance is increased further, but only when the KWin option "suspend desktop effects for fullscreen windows" is enabled. It seems important to use exactly this option and not just turn off KWin manually. In this case the apparent performance for some games running under wine becomes the same as if they were running natively in windows. All movements became much smoother, I have never seen such smoothness in linux with any configuration.
If not the bug 974041then I would say I am completely satisfied now.
It seems that KWin and possibly X were largerly responsible for this performance loss.
