I've created an Infinite Voxel World, similar to Minecraft

Downloaded and tried out, and while my system is far from a powerhouse I do well "

Phenom II x4 3.2ghz, 8gb ram HD 7750 2gb ( prob. weakest part of system oh well) .

I ran your example but not only was the menu rather laggy, but moving mouse around had severe lag to point of needing to exit. I was surprised given statements about it running well regardless of size of world, etc.

What should this take to run smoothly ?

Thx
