All of the Psikyo games I've tried sound perfect. Daraku Tenshi, Strikers 1945 I, II, III, Sol Divide, Space Bomber, Dragon Blaze. Can you check to make sure your samplerate is set at 44100hz or higher? Also try 6 or 8 for buffer size if you have a old p4 pc like me.. (or smaller buffersize if you have a newer pc).
