Okay found the same bug as the previous incremental update.
I set the performance "power save" first, then to "performance", the highest possible performance setting, then launched nba 2k16, a very graphics intensive game.
While playing the game I noticed that the game was laggy unlike in cm12. You have to restart your phone then select performance to fix it.
It seems whenever I select the "power save" option, the phone significantly slows down even though you then select the "performance" option.
