Minecraft glitching :(

[Thorin]

So on my old machines with 1.2.5 installed I used OptiFine to get a workable FPS rate (went from 25-30 to 45-60, so about double).  With 1.3.1 installed on those same machines, I'm getting 53-57 FPS rate _without_ OptiFine.  That's quite the performance improvement Mojang made.  I checked just now and OptiFine is now available for 1.3.1.  I'm going to install it to see if I'll be able to play with Render Distance: Far even though they're 32-bit machines; that would be awesome.

As Lazybones said (in game, I think) OPTIFINE SHOULD BE IN THE CORE OF MINECRAFT.  It makes it run so much smoother and look so much better (MipMaps for the win!)
