Looking into my BIOS i found HPET as a setting and googling around i found this article
The juicy bit:
Disabling HPET removes the micro-stuttering and screen tearing that may occur during gameplay. It allows unrestricted input-output to occur. This results in a very raw and extremely responsive connection between you and your PC.
You can sense around 0.1 to 0.15ms delay with HPET on while turning it off can gain you around 3-4 FPS. This may not seem much for day to day use. But with gaming, imagine the FPS drop for every action piling up; this leads to micro-stuttering that is observed during gameplay.
Has anyone else played around with this setting?
Edit: Seems to help for me. It might depend on a case-by-case basis.
You can benchmark the interval times with Timebench (higher is worse)
