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.
i have no app, using third party ones
Any idea how can I change GPU set up?

GPUs are not so strong in cryptonight in comparation for example with equihash algo. Sometimes, you need to accept your hashrate, you cannot do wonders with a single card.. Imagine, worldwide hashrate is around 1000 MH/s.. worldwide..

My hashrate is 550 MH/s. I'm OK with my results (hashrate). I don't want to do wonders, as you see I even ask you to reduce the power which going for mining. Maybe you didn't understand me.
