Minecraft problems

[Luke.]

Minecraft is generally quite a hard game to run because of it being java. Java doesn't run multi-threaded for some reason and therefore you could have the best CPU in the world and it still wouldn't run that great. It all depends on clock speed where that's concerned.

1GB of RAM should be enough BUT it requires a lot to run besides other desktop applications and therefore allocating all of it will choke your system and therefore Minecraft will barely run either. Allocating any less and Minecraft struggles so...it's a lose lose really.

My only advice is use the lowest Graphics settings (fast graphics, low render distance etc) or just have a general play around with the settings and see what you can do. Don't use a texture pack either, if you are.
