Pro, my Laptop runs with out any glitches under a load[other applications] at 15ms, I could try an even lower latency and gamble on a pulse or hic up, but why? Not even yourself can tell the difference between 2.2 and 15ms..It is plenty fast..BTW, that must be some sound card that you are using, my B4 shows intervals of 5ms, the lowest at 10ms, the highest is 400ms...Yours is so accurate that it shows decimals[2.2ms]..Of course ASIO is the best drivers , but all applications will not work with it, that is why the Direct drivers are a good choice overall and beside, they work..
