I bought an audio interface specifically to take some of the cpu load and make it smoother as well as reduce the latency, but once again, although it did help somewhat, I'm still having to boost the buffer to the mad and it's still crackling and freezing. I've run out of ideas. My computer's CPU and RAM is decent from what people have told me (2.3ghz and 8gb). I don't know what to do anymore, and I don't understand why I'm the only one who is having this problem so badly..
