When is windows GPU mining coming?
guli, the original creator of the GPU miner was working towards getting a Windows GPU miner out, however due to the hard fork and implementation of the algo, it really wouldn't be worth it. The power consumption alone would outweigh any profit.
As a guide, a GTX 1080 was tested in Linux with the GPU miner and h/s were below 1, an average of around 0.45. As such due to the nature that the coin was originally designed to be CPU only, a GPU miner is not something that would be viable in my opinion.
In reply to the people that were concerned their wallets are showing a 0 balance for quite some time, if you are mining on a low h/s setup and your accumulation of ARO is not very quick, please bear in mind that a minimum of 10 ARO needs to be mined by yourselves before it is sent to your wallets.
Hope this clears a few things up
