    Is turning on speedshift with epp = 32 increasing cpu performance and heat?

    I don't think so.

    it actually does in games.

    Update.
    Just tried 32 and 128 values, with 32 i had good performance in HotS (same map), while on 128 i had a bit lower fps by 5-10 units. Also lower EPP causes a bit higher temps (because of clocks i guess)

    RTFM (or use search function) on the main ThrottleStop thread.

    EPP is essentially a weighted setting that affects what multiplier your CPU will be centered around.

    It does not affect clock speeds directly, but does affect how much time your CPU spends in a given multiplier range out of its total usable multiplier spectrum.

    So in short, a lower EPP setting is going to keep your CPU running at its upper limits more of the time and a higher EPP setting will keep your CPU down towards its lower limits more of the time. It DOES NOT actually make your CPU clock speeds any faster though (those stay within the same limits), only the CPU's responsiveness to a given load.

    AKA:
    EPP == 000 --> similar to desktop
    EPP == 128 --> similar to laptop/notebook
    EPP == 255 --> similar to ultrabook

    I'm not certain but I think that's what the new battery slider on Windows 10 controls when running stock or without TS. If correct, that means the battery saver end of that slider increases the EPP value and the performance end of that slider decreases the EPP value on the fly. I have a feeling there may be a bit more to it than that though.

    So i think it's better to turn off SpeedShift EPP control in Throttlestop and let windows power plans to control it?
