Hi,
I ran clBitCrack.exe on Win10 and when program started generating keys my computer became really slow. CPU utilization was only 8% but everything was really sloooow (youtube, web, windows). I tested multiple -b  -t -p and the only difference was that it generated more keys. Is there any solution for this? Does this happen with better cards too (like GTX 1080ti)?

Ryzen 2700x +  Radeon HD 5700

Thanks!
