anyone have a good optimization for cryptonight heavy or light for vega 64? I get 2k hash on regular cryptonight but I get around 1400h/s on cryptonight heavy and 16600h/s on cryptonight light
Decreased hashrates on the other algos you mentioned are normal. Cryptonight-heavy is called heavy because it exerts a heavier load on your CPU processing power. You don't need to worry about anything because every one has decreased hashrates and that is the new standard hashrate.
