Ok I'll see if I can run it.
Edit: It will run, but I only get 1fps. I'll try to tweak it some more, try some other things, as this was with graphics set all the way down.
Edit 2: After installing Optifine and extensive (like two hours worth) of tweaking, I finally got it up to 15-25 fps! I can actually move around! It's going to be a bit tough, but I'd say it's playable. So Crabbie, whaddya say we team up again when I'm at random truck stops to build awesome stuff?
Edit 3: I'm stuck indefinitely in Laredo, TX waiting on a load. I normally drive during the day and play from early evening to about midnight before sleeping, then start all over again. They tried to give me two different loads out of here, but the first one was missing the paperwork, so they gave me another one, but the trailer had a blown tire, and by the time it was fixed I had been awake for around 16 hours waiting to leave so I took a nap, and when I woke up (10 hours later, was more tired than I thought) they had given it to someone else.
TL;DR, Today would be a great day for Minecraft, probably won't even have to move this truck until Monday (thank God for the man who invented Freon Air Conditioning).
