KDE 4.8 我記得有很大的效率改進啊
去年 KDE 4.6.2 表現優異
怎麼今年反而差人家一截 @_@

"Increased overall performance: KDE 4.8 seems to want to think it is
XFCE and so it performs remarkably faster than previous iterations.
This even holds true when special effects are turned on and heavily
used. In fact, it’s almost hard to compare 4.8 to previous iterations,
simply because it is that much faster."

BTW, 還沒有試過 KDE 4.8 的
如果是 kubuntu 11.10 的話 可以參考這個 link

Install New Release KDE 4.8 on Kubuntu 11.10

當然 要試用 kubuntu 12.04 也可以 我已經用很長一段時間了
沒發生什麼問題

不要太介意benchmark……
老實講4.8我玩東方系列開著模糊特效都能60fps了，之前都不行的。還是窗口模式（於是沒有自動關閉混成特性）

按評論中所說，kwin默認不禁用全屏窗口的redirect了

Yea, KWin doesn't unredirect fullscreen windows at all by default,
because it causes annoying screen corruption when combined with
overlay windows (like the Amarok OSD). So while it should be
considered a bug, it still explains the poor performance. To be fair,
all tested games should have been run in windowed mode, in order to
truly compare the compositing performance, and not the unredirection
performance.
