I don't know how to explain this, but since I've updated my OS X to 10.11.3, keyboard seems to lag. It's extremely subtle, but I am a programmer and an author, and I can feel the difference while coding or typing, and even it's something in the milliseconds-range, it's noticeable and disturbing. I've tried restarting etc, not using many programs at once, but no avail. It's noticeable everywhere, even as I'm typing this question here. I haven't installed anything extra.
I'm in a mid-2014 MacBook Pro with the built-in keyboard. The problem is keyboard language-independent. The problem occurs system-wise, from TextEdit to Safari to Xcode, even inside Windows apps using Parallels.
Is anyone having the same issue?

I would try to disable some keyboard-related applications, if you have any. Such as:
I have just got rid of the keyboard lags on my system by uninstalling all of these (it could be only one of them that caused the issue, but I've shot all three).
