My Nexus 7 device runs smoothly, until I try to play games with it. Whenever I try to play games such as Real Racing 3 or Riptide GP 2, it runs somewhat smoothly, but stutters randomly.
I ran some benchmarks for the device and nothing seems to be terribly wrong with my scores...although they seem to be slightly lower than average. (5-10% lower)
I'm guessing that the stutter has something to do with background processes....but there was over 1 GB of ram when I checked. (not playing the game) And I know its not a wifi issue because it stuttered with WiFi off.
