Uh??

sounds sweet but, ... wtf? how do you do this on Windows?

that lets you set the affinity to a service, but how would you go about setting the polling rate to a single core?

i'm asking because i both play quake, and i'm also calling you out on your - possible, yet astonishing - claim.

< not as much of a noob as he makes out to be

If you set everything else, then the windows scheduler will dump what's left on the empty core you leave it.

The problem mostly is that the windows scheduler likes to rotate threads at a blazing pace in an attempt to make things feel responsive to the end user.

This has a negative effect if you are at maximum load, such as a multi-threaded game that's actually optimized properly.

If you empty enough space for the aforementioned background processes to give them breathing room, the windows scheduler does the rest for you.

This is quite important since a 1000 hz mouse can take up to 30-50% of my processor time of one core even on a 4.6 ghz ivy bridge.

If I do not do this then any spike in usage will be met with a latency in response of my mouse in situations where the processor is fully loaded or even 75% loaded with windows' scheduler's thread rotation.

I suggest using Sysinternals Process Explorer if you want to learn more.

I got a 1000hz mouse. And I cant even get it to use more than 1% when my Haswell runs idle at 800Mhz.

The more loaded your computer, the more actual cpu time your 1000 hz mouse wastes in it's translation to screen movement. This is because every time your computer is too slow to keep up with your 1000hz mouse something happens repeatedly until it catches up. This wastes the cpu time.

It's like a snowball effect that piles on more and more and more causing increasing rate of processor usage.

thank you , i actually understood that
