Hi Derek, after a year of on and off problem solving, the issue on my surface pro 4 with major latency came to running SD3 as standalone. Not sure why, but when i run via reaper as vst i get no latency problems. I use zoom r24 as AI and Roland UM-one as midi to usb controller. No problems found anymore and way more stable. No crashes, no blue screens, etc… Hope that helps
