I played Rocksmith for nearly 3 years without any latency issues. But, 2 months ago, I bought an audio interface to my home studio, and I use it as my main sound card now. But since then, I just can't play rocksmith because of the latency, it's unplayable with this nearly a second long delay. I tried everything, I changed the settings, and so on, but nothing. It didn't get better. Any ideas how can I fix the problem?
