So I received my 15in 2.7 512 460 on the 15th and it has been a blast to use. Before this I used a 2012 rMBP as my daily machine. The problem I have been experiencing with LoL is after loading into a game, the screen will freeze but the game continues to run in the background. Shop can be bought from, items moved, etc. This issue doesn't happen on my 2012. I play in fullscreen and have tried resetting and using different graphical settings to no avail. The screen unfreezes after minimizing and reopening the game client a random number of times. Sometimes it doesn't freeze at all and other times it will take 10 or more min+max to unfreeze. This is extremely frustrating because of my having to be afk to fix this. Is anyone else experiencing this on their new Macs? I feel like it has to be an issue with the new ones because of the lack of it happening on my 2012. Any help is appreciated.
