It doesn't switch usage from first to second core. I meant that the image from
the first attachment looks the same for both values of affinity mask.

Setting affinity mask to 3 doesn't change anything. It seems like affinity mask
hasn't any influence on the usage of cores.

As you can see the usage for the first core is 100% and for the second is
20-30% so it seems like the second core doesn't work.
