intel speedstep, when disabled, causes massive FPS drops and locks the CPU to a very low frequency. When enabled however, it doesn't let apps use the full potential of the CPU, even without throttling. My PC has been to service 2 times and just came back, fans, heatsink etc are replaced, the DELL guy told me where was no throttling but they wanted to make sure. So yeah, it's the setting that is holding the CPU back in all cases.

HPET on the other hand, cannot be disabled from the BIOS unlike ANY other notebook, prebuild desktop or custom desktop on the market, and HPET is known to cause major problems in SOME cases, including my case: mouse-keyboard input lag and stutters. So I want to disable it but the limited BIOS won't let me.
