That thread is ancient and the user who posted that was explaining things from his point of view, it doesn't mean it will be the same for all users or that he is right. If HPET active on Windows was so amazing and epic and whatever, then the O.S would have it active as default; yet it doesn't. Windows uses TSC; HPET when its needed, no need to force it on or off, I believe if an user fully understand its functions, then they could force it on for a particular program or application, the rest of users don't need it on because Windows manages it. Stock HPET+active on BIOS is the best setting: I'd rather believe a real video than some telling me to force a timer on my O.S that doesn't need to be force, because its actually dynamic. He also said this (from the thread you linked): "Fortunately I have to say that useplatformclock defaults windows to the best that the clock has (cpu), but is it so with mb's?" He doesn't even know what he is doing or changing, it just seemed ok for him, that's it As for latency, well, this my system: https://imgur.com/a/XqOkjuS And if your whole post is sarcasm, well then, I fully fell for it, because taking advice from a random post from a random user that has no idea on anything its something I refuse anyone from here would just do.
