Anybody knows why TR miner on Polaris cards (470/480/570/580/590) builds DAG so long?
TR miner build it in about 12-13 sec. on my 580 8Gb cards. 1st of all I'm thought that it's only 1st time after launching (cache, etc.). But every time when DAG changes it take so long as at launch.
But other miners (Claymore, lol, Phoenix) builds DAG about 7-8 seconds.
