    I been playing with hpet off for afew weeks, forgot i turned it off, after remembering and turning it back on games feel smoother more responsive and more fps in some games like PUBG. I just disable hpet in device manager, is that the best way to do it, or? Also this is on an intel machine.

    That`s the best way to not do it. Disabling the device in Device manager does not disable actual HPET (and does not prevent any kernel mode code to use HPET).

    It's easier for a meteorite to fall and the planet to disappear than for this post to have an end, I've given up using these settings.

    Has been so for years with good drivers and no messing about, the currently known thing that can affect DPC latency to the negative are Windows MPO's and Nvidia drivers since 461.09, Nvidia is working on it and has some users currently testing a fix, so that fix might be in the next driver release.
    Nvidia provided a workaround for now though:
    After updating to NVIDIA Game Ready Driver 461.09 or newer, some desktop apps may flicker or stutter when resizing the window on some PC configurations | NVIDIA (custhelp.com)

    Other things that will spike Latency Monitor are power saving/throttle modes and settings.
    As example, using the Windows build in "Power saver" plan will add spikes as soon as a program/game triggers the plan to boost the CPU, at least with Zen 3 CPU's.
