Yes I know that. I just needed answers for the questions because this is some serious issue I believe.
Still no reply
My gpu hash rate is halved now.
Here I have created new workers but the total is still adding to default. Also, on my new rigs the hash rate is lower than before.

When I created the new config with the new xmr software that you have updated on the homepage on new rigs with new "WORKER NAME". The hash rate of the new workers were added to the default one. Getting me now?
Moreover, with the new xmr-stak the hash rate of my gpu was halved. So I shifted to the old config for now on them. Why this happened too?
