Client memory update when no focus?

[skypa]

Hi,

excuse the clunky topic title. I'm writing on a waypoint-ish bot on the Linux side, implemented in ruby. Quite simple yet, but it'll get along.
I wrote plugins in C to attach to the process and to generate fake key presses and mouse events. Unfortunately, the WoW Client seems to fall into some sort of sleep state where it doesn't eat as much CPU cycles as soon as it's i.e. minimized or somehow lost the focus. When in said mode, it seems that values in memory are seldom updated. I turn my toon and get an updated rotation angle waaaay to late for my bot to react.
It works fine when the game has focus and I'm seeing the toon in front of me.

Does that kind of behaviour occur too on the windows side and if so, is there a way around this. I'd love to write my bot the way, it doesn't need the users focus to do it's job.
Kind of the main aspect of a bot, right?

Thanks for the help.
