Another question

I do mining graphic card + CPU at once following this instructions:
https://bitcointalk.org/index.php?topic=2527462.msg28396744#msg28396744but graphic card get too busy and PC didn't work properly for other tasks.
Is there any way to reduce the resource on graphic card which goes for mining.
For example if now 85% from graphic card power goes to mining I want to reduce it to 65%.
usually, you can set up on mining apps the intensity of your GPU (lower intensity = lower performance, but more available to another apps)
I ask specially for your product/app.
