I am getting ~2.25khash/sec when autotune uses T9x2 on a GTX 780 3GB.
If I type gethashespersec in the console of YACoin wallet, it tells me 0, is that correct?
Using Windows 7, disabled the Aero theme.
Using 2518MB VRAM total, T10x2 or T20x1 seems to be slower and using more VRAM.
Am I doing it right?
Sounds about right for Windows. It's normal the YACoin client doesn't show your hash rate - it'll only do so if you are CPU mining from the wallet itself.
