As the latency is extreme with this game, are there any WASAPI based soundcards with very low latency that can be recommended? A card with audio output latency of no more than 5ms would be good. I have asked UBISoft, but they remain unresponsive on the issue of Rocksmith latency.
(I do suspect that WASAPI is stuck with a kilosample or so of latency inducing internal buffers (ca. 20ms), but I'd be delighted if it isn't so for all soundcards)
