New Post: How to tell MagickNet 7 to use more CPU

I have an update about the situation :
Now we know what cause the 100% cpu usage. We installed a new graphic card and installed the AMD Catalyst software and driver. After that the CPU usage goes high for composite and shadow and Blure commands and some other commands. I changes again the graphic cart but still the CPU usage is 100 percent. I know it seems silly but wait. I installed the same graphic card on one another machine which I could not increase the cpu usage on, then after the installation the cpu goes high. I change the graphic card on this one and then again I have 100 percent CPU.
We thought that at both machine it was by chance, then we do the same for one of our production machine and then it start to use the cpu for 100 percent.
Is there anything in that softwares that enable for force CPU to be used 100 percent? I read about that software and the Mantle API is installed as part of the software. I could not find any other explanation.
how is possible the usage of CPU goes high, and not use the OpenMP. Is there any other way, that that software/driver make provide it.
