Well, the header is self explanatory... To be honest I just started using Dolphin a couple weeks ago so I'm no expert yet clearly.

For example and to begin with, Star Fox Adventures runs far too slow except when switching to D3D11 but subtitles, transitions, some backgrounds, some effects, fades in/outs are all missing. OpenAL does work better with some other games but having a couple too many sounds occurring at once causing crackling audio is kind of bothersome (some games it can become unbearable). Metroid Prime's (the first one) speed is also sometimes schizophrenic. Um, I can't think of anything else I'd like to add. All I can think to do is list my specs if it's of any help.
