on my system the useplatformclock YES even with hpet on bios disabled cause freeze.

It's unbeliaveble that a parameter for debug purpose (said by Microsoft) it's enabled by default at every start maybe by the Amd drivers. This is an huge issue since Windows 7

it cause also some kind of issues with a game (maybe more than one)
