What I expect to happen: Minecraft is a "cube" game and should not require an impossibly powerful computer to run. The game should run without problems on each new computers/laptops, especially with enough memory and a non-integrated graphic card. I also expect the game running properly without the need of installing any external optimizers like OptiFine.

What actually happens: the game seems to require more and more powerful hardware, just like 3d-games of the type of Assassin Creeds. It causes many players not to use newer versions of MC because their hardware cannot serve the game. It is not good for the game, it is becoming elite. Instead, it is expected to be available for everyone (with a newer computer and especially with a newer laptop).

Why the game does not have enough optimizing mechanisms that using external mods like OptiFine is required for many players just to run it? It is expected that the game will provide at least the same possibilities as OptiFine internally, without the need of using mods.

Walking through jungles in 1.6.2 does not cause my game to stop. But it happens in 1.7 snapshots. Why? Has the jungle been modified too much from the previous version? I do not see enough changes. Now the game can really stop for few seconds (with fps = 0). I did not observe that before.

The game really needs much more testing on normal machines, without a super powerful mega graphic cards and 1000 GB of RAM. Or, hardware requirements should be given more concrete than just "newer computers" as it is not true: even on newly bought computers the game can refuse to run properly.

In addition: strange enough, but the game goes better on 32-bit Java than on 64-bit Java, on my 64-bit machine (with Windows 8).

The same problems, even more sharp, are seen on another computer, with a 32-bit processor, Windows XP, 4 GB RAM, NVidia GFX.
