Hyperthreading off = stutters off.

[SEE]

In the Nvidea control panel is the option of 'threaded optimisation' which can be 'auto', 'on' or 'off'. I did some reading using google and there are a wide range of opinions regards this parameter. I just tried the Black death track with it switched 'off'. (some say the 'auto' feature is bugged but may be that applies to earlier Drivers)

I didn't get any stutters or pauses (just a drop in fps as the bombs hit) but should this be 'on' and how does it relate to this discussion regards hyperthreading (especially for us whose BIOS doesn't allow the user to disable HT)?
