hello, I'm a newcomer and I really would love some questions answered
from can you can see in this pic:
is this a good card?
no. That's your onboard graphics.... not a GPU.
is that amount of khash/h decent?
No.
how can I maximize my performance?
Get a GPU.
am I even really mining? I havent recieved anything.
Yes, it's mining. But that's not your username/password. It's probably username: minero_worker password: changeme, if you haven't changed it.
how can I know for sure that I'm in a pool and not solo mining?
Because you chose a server.... in the server option...
