Reply to Traktor Pro 2.5 CPU overload

Hey Guys, i downloaded the new update and after installing it i started Traktor to play around with my S2. Even when i am not doing anything at all, the CPU load is nearly in the red space... Anybody having an idea what to do? I own a Windows Laptop with intel i5(2x2.3-2.53GHz) which shouldnt be the problem...
