Large delay before a key registers you say? That sounds more like a hardware issue than a syncing problem. I've never heard of latency issues for a keyboard that bad. That has nothing to do with being a "pro stepper"...see if you can find a way around it. I could be wrong though if your keyboard's responsiveness works well for everything else.

I also recommend downloading v3.9 as opposed to v3.95. Hopefully you weren't trying to do the latter.
