Got a problem with high CPU usage from wot? If you have a multi-core processor could use the following procedure. At the core i5 430m helped reduce CPU usage by 7%, not much, but especially for laptops it helps. It is only a tip that works for me, I'm not saying it will work for you

The whole procedure must be repeated each time you start
1st Turn on the world of tanks
2nd Start Task Manager (right-click on toolbar)
3rd Get the processes tab
4th worldoftanks.exe find - the right to look at the percentage of CPU utilization by process
5th rightclick - Set Affinity
6th Leave the check mark only one CPU
7th effect should be immediate, if you try running the game properly
