As an difference from preview version, this one starts and works fine without hdd swapping (win 7 x64, 17.4.3 drivers, r9 280x). But performances are awful, 9-13 sol/s but with average of 12, roughly half of 1060 3GB on new EWBF 0.3 which makes it currently totally unprofitable to mine with. Hope for much better performance in next versions (r9 280x was getting 280-300 sols/s vs 300-320 1060 3GB on 200,9 equihash).
