Hi. I need to reduce the performance of the GPU. When the kernel OpenCL running, OS is not responding(even Ctrl+Alt+Del) and I have to restart the computer. That it will be not 100%, but let's say 90. When I do one famous benchmark test, I can see that its performance is less than 100%.

I'm sorry but I'm new to OpenCL. Where I can register in the code this limit?
