I'd suggest checking the buffer size in DP11. See p. 247 in the manual. I usually have mine set to 512 or 256. But you can experiment with higher values to see if that solves the latency problems you are experiencing.
From the manual: "You also have a third option: turn off your audio hardware’s “hardware-based” monitoring andlower the Buffer Size setting. The default settings is 1024 samples. Try lowering it to 512, 256 or even 128 samples. This gives you the best of both worlds: very low monitoring latency (3-6 ms) with effects processing. The trade-off in this scenario is that the lower buffer settings put more strain on your computer."
