@vertcoin:
The GPU miner link on the main thread is broken:
https://vertcoin.org/downloads/vertminer-0.5.3.zipAnyway, there's no further optimization being worked on the vertminer? There's no new version in months.
FYI, the x11/x13/x15 miner recently got improved again, and got even better with the recent ati 14.6 rc2 driver.
Here's hoping maybe scryptn can also be improved somehow.

The Scrypt kernel is fairly mature at this point since it had over a year of development. Scrypt-N is basically just Scrypt with a bigger memory requirement. X11 however, was sorely unoptimized in the first place, hence the lower power usage.
