Ok, I think alot of people here have had problems with minecraft, where the screen suddenly turns black while having render distance "far " on.A temporary fix is to set the render distance to "normal" but it ruins the view.

So I searched a little bit on google, read several topics about allocating more ram to minecraft. I tried it, but for me it didnt help at all. So I thought the problem maybe could be with java, so I updated it and still it didnt work on "far" distance without crashes. I located their website and noticed that they have a new beta version of java. I thought that could be cool to try. So I downloaded the beta (aka java 7), uninstalled java 6 and installed java 7. I started up minecraft and tada! I could run minecraft of "far" render distance without crashes now!

So if you want to try link here: http://download.java.net/jdk7/
This is beta, so it can have some bugs, but I havent encountered any. yet.

Thank you very much. This has been an issue for me for a while but I never bothered searching for a solution. I pretty much just chalked it up to my laptop's age. This has definitely helped me. It would always crash on me at various intervals with render distance to far and sometimes even on normal. It would always happen whenever I warped with it on far. I have installed Java 7 and have played for a good 1/2 hour with no crashes and tons of warping just to be sure.

I hope other give it a shot if they are having this problem.
