For example, I was playing max payne 3, i was getting 30fps, but game runs slow. Frames are not fixed. I will upload a video about my problem when i'm home.
Known and unaddressed issue, sorry. This is precisely why I haven't upgraded my EFI or OSX on my launch rMBP. Gaming under Windows/OSX right now is excellent and Apple won't wreck my laptop with poor updates.
