56% CPU usage in garage, and 100% In game.

DORIAN96, on May 26 2012 - 06:57, said: I've played the game for a while, 2-3 months without a problem, no graphics lag or slugginess, and then after not playing the game for 2 weeks, I came back to see
55 to 68% Usage when I'm idle in the garage.
and no less then 90% Usage when I'm in actual battle.
Can someone please answer my questions?
1. What causes this?
2. Is there any short term / long term solution I can use
3. Are the devs aware of this problem and working for a solution?
Thanks! Matt.
