Android 4.2 latency

So I just got the ota update to 4.2 on my galaxy nexus yesterday and everything seems even more fluid, building on improvements from 4.1. However, I started playing some games- Edge extended, Canabalt hd, where the speed at which touch is registered is very important. Much to my shock, there was a very noticeable 1-2 second lag before the games responded to touch. Also, in one of my music apps (musical pro) the onscreen piano keyboard showed lag when pressing keys. In other apps, however, lag was practically nonexistent. Is this lag maybe caused by apps not having been updated for 4.2 yet? If you have any opinions feel free to comment.
