I'm shocked what I see here. I've been out of GPU mining lately, but getting 6mh/s + with 280x got me thinking.
I was getting 3,15 mh/s max
can someone pls help me how to get started (again)?
I see there should be .bin file replaced? do I have to rename .bin in some specific name or...?
this miner is a compiled version that already includes the bins. You need just run it on a compatible machine. If you want to build it from source, download the source from the same place where binaries are available (see OP). The generated executable will include the bin. No need to rename it, replace it or anything.
Please be aware of this warning from the OP:
WARNING: This is not a free (as in beer) version. This version of the miner mines 2% of the time as a donation fee to the developer.
