I have noticed recently that when playing videos or games there is a slight but noticeable stutter every five seconds or so. I noticed it the most with games like riptide and shadowgun. The funny part is when I first had the nexus 7 before I believe the 4.1.1 update I ran right through riptide with no hiccups, so I'm guessing its a software thing. Everything else runs very smooth, it just seems like its anything is using hardware acceleration at all. Anyone else having this problem?
