    Hmm...You sure?
    Code:

    # CONFIG_HZ_250 is not set
    # CONFIG_HZ_300 is not set
    CONFIG_HZ_1000=y
    CONFIG_HZ=1000
    CONFIG_MACHZ_WDT=m

    I'm sure I saw the option just yesterday afternoon when I was creating a custom config (using menuconfig) using the stock configuration as a template (for precisely 2.6.22.7-85.fc7) I'm not sure, then if 2.6.22.9-91.fc7 does so.

    Aaahhh... Now this is strange. The CONFIG_NO_HZ option supposedly turns the kernel into tickless (it is not present in the x86_64 kernel, there are still issues with tickless and x86_64), I don't know why is the CONFIG_HZ_1000 still set as 'y', though.

    Default Only ONE Game?

    Am I the only one to notice that they only used 1 game to compare Linux Vs Windows? Is this because someone got too lazy to test others (like the Doom3 they did the initial Linux SLI review with) or because the numbers did not promote Windows? I have just finished setting up my Linux SLI system - and will do some personal testing, and may even post some results... but this seems like very poor reporting to me.

    If you are going to test and compare, Do it right. I have seen major performance differences like those just from going from XP to XP SP2! OR even from one driver to the next!

    I am sorry that my first post on this forum is not a positive one, but no one else mentioned the obvious... ONE game is not PROVING anything.

    Sorry bout that; was looking for info on the whole SLI in Linux bit... came across this article... despised it, and replied... didn't think to check the date on it.

    So what about your tests?

    Has SLI performance increased on Linux?

    I am planning on going for SLI
