As much as I enjoy reading the overwhelmingly idiotic comments about Gentoo / Linux / Ubuntu and FreeBSD, I guess its time to say:
It was a sensational story for the sake of, well, writing the sensational story.
I can't possibly believe that someone @Phoronix done two bencharmks in the same week, one ignoring the WM differences between kwin and Unity, and a couple of days later, a second benhmark comparing Unity to Unit2D and GNOME shell showing the huge effect a WM can have on gaming performance without connecting the dots.
1. Kudos to the nVidia driver team, period. (Whether or not Linux / BSD / Windows is 5% slower or faster is completely irrelevant)
2. Last time I checked (7.3), the 64bit driver was noticeably slower than the Linux driver; I guess its time to install FreeBSD 8.2. (Or should I wait for 9?)
3. Beyond rethinking the very, very, very, questionable benchmarking methodology, isn't it high time to reconsider the selection of Ubunutu as master of all things?
As an alternative, I propose the following:
a. On each release cycle compare the 3 top distribution (e.g. Fedora, Ubunutu, OpenSUSE, etc).
b. Determine who's the best performing distribution.
c. Use *winner* against BSD/Windows/MAC/Android/DOS.
d. Sound's almost, err, logical, isn't it?
