I recognized this issue of graphic stuttering and fps drop several times while playing Asphalt 8 on my device ( iPad air 2 wlan 64 gb). In my opinion it has nothing to do with the capacity of the device and it doesn't matter if I close all apps in the background before playing or not. The framerate drop in Asphalt 8 occurs only from time to time whether there are any opponents or not and is quite annoying. After a few seconds of stuttering it seems to get better again and the game runs smooth but the framerate drops itself should be noticed by everyone. Even Real Racing 3 doesn't seem to run very well and you can clearly see some stuttering or missing frames. Any experiences regarding this issue?
