Skype Videocall = 100% CPU Usage

[mintscriber]

Hi Community,

i'm relatively new to Linux Mint. I'm very happy with it but nevertheless i'm having a big problem with skype.
Everytime i start a videocall my cpu usage turns up to 100% (processes: skype = 100%, pulseaudio = 12%, no other process have a high usage) and this is so loud that the receiver means i have a turbine in my room.

* My Hardware is a Lenovo T420
inxi output:

CPU~Dual core Intel Core i7-2640M CPU (-HT-MCP-) clocked at Min:800.000Mhz Max:2801.000Mhz Kernel~3.0.0-12-generic x86_64 Up~2 days Mem~1295.0/7884.9MB HDD~160.0GB(13.4% used) Procs~172 Client~Shell inxi~1.7.7

* Skype Version 2.2.0.35 Beta

* OS

I solved the general fan issue already with thinkfan. The problem consists only within skype.
It would be very cool if anyone have had the problem and could help me with this issue.

thanks and best regards

How did you install skype?

also does the pc get sluggish at all?

[mintscriber]

i installed it via installation manager and nope, the os runs fine. everything works well but when i start skype vc the process usage turns to 100%

[mintscriber]

is the reason maybe that i installed the x64 bit version of mint and skype is designed for 32bit?
