Minecraft 1.6.2
So, after a year or more of no Minecraft, I had decided to install it on my new MBA which I've had for about a month and a half..
Decided to uninstalled the game.. later today..
But if you are on the look of purchasing the game, I can tell you it has good frame rate, at 60fps on all highest settings at 1440x900 with a "normal" amount of entities (monsters) around me, sometimes dropping to 54fps. You can easily ramp up the frame rate to 100 fps if you lower some settings. I was getting no lag whatsoever, good colors and contrasts, very very smooth renderings and very fine and detailed as well. First time I see Minecraft so "pretty".
My reason for uninstalling the game, is very personal: The side where the magsafe port is, above the GPU, started to boil at a temperature that I didn't like. Obviously will get hot. I am aware of the thermals and capabilities of the computer including intel's forced shutdown if temperatures get too high; but this is the first time that I hear the fans on my MBA and the first time that it gets so hot so for me it is a no no, I need to take care of my computer during my Senior year, and throughout my entire Master's, so I decided to back down. I will not have time to play the game anyways during school time.
Please do not get discouraged from my personal view, the MBA can take a lot of heat, but I personally do not like to even have a warm computer next to me, much less hear the fan.
You can easily tell.. after a year or more of no gaming, I am not a gamer anymore. Haha.
One more thing, because Java 6 SE is needed to play the game (the game downloads and installs it by itself, with permission of course), I was a bit skeptical of uninstalling Minecraft and leaving Java on my computer, so after 5 minutes of messing around with the Minecraft folder and seeing the same on the web, the Java Plugin for Minecraft is stored on Minecraft itself, so if you delete Minecraft, you delete Java as well. This makes life so much easier.
Hoping my review, helps someone out there.
Buy the game, play the game, it is a great game!
