这 Tiger 里据称就是原来的 Quartz 2D Exteme,到 Leopard 里换了个名字叫 QuartzGL 了。刚刚在 Quartz Debug 的 Tools 菜单里看见有开启它的选项,所以就开了一下,用 xbench 跑了跑测试,结果居然比不开性能还差,而且还导致一些应用程序的不兼容现象出现(QuickSliver 启动画面成一半透明白框,据说Dashboard也会有问题),所以我还是关了。
开启方法是:
$ sudo defaults write /Library/Preferences/com.apple.windowserver QuartzGLEnabled -boolean YES
恢复方法是:
$ sudo defaults write /Library/Preferences/com.apple.windowserver QuartzGLEnabled -boolean NO
注销即可,不过我为了测试结果的准确性重启了电脑。
开了后的结果:

没开的结果:

注意:因为单独的图形结果和完整测试不是同一个时间完成,所以数据有所偏差
