    Gaming Tweaks

    I would like discuss here some gaming tweaks, which don't give sense to me.
    [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Multimedia\SystemProfile\Tasks\Games]

    For example "Priority"=dword:00000001
    On msdn they mention, that priority 1, means low priority.
    I know, that high priority is not recomended, because it might affect stability of system, but low make no sense as well.
    In process lasso appears below normal, like low.

    "SFIO Priority"="High" i have that in registry and process lasso showing me still normal, weird.

    "Scheduling Category"="High" this i understand, you want more priority to sheduling your game at first place, what makes stranger, that priority is recomended to low.
    I don't understand much what priority alone does, especially if you want keep it on low.

    And what do these 2, affinity you set at launch parameters with mask today times, or ingame, so that probably doesn't matter.
    "Clock Rate"=dword:00002710 (default: 2710, recommended: 2710)
    "GPU Priority"=dword:00000001 (default: 2, recommended: 1)
    Again i don't understand why 1, it is lowest priority from 1-31.

    "Affinity"=dword:00000000

    SFIO Priority - it is not used in all OSes, and it is only used by games that interact with the MCSS.
    Affinity was only needed for some older games that didn't work well with multi-core CPUs.

    Hey YoS

    Leatrix latency fix only disables nagle's algorithm, same thing is in the TCP Optimizer as well. Isn't disabling shadows game-specific ?

    I reworded and added information to the article. You are correct that "priority" should be something higher than the default of 2, however, it only has effect if "Scheduling Category" is something other than "High", so it doesn't apply in this case.

    GPU Priority had an error, fixed. Thanks.

    Okay thanks for explanation.
