It will take a week and if you don't have your computer set up just almost perfect you'll have problems. You should be rendering to disk with such a size but that in itself is tricky cause you have to save the file with the render settings you want to render it then render it to disk. You basically can give up using your computer for anything else till it's finnished unless you know how to put Vue from normal cpu usage to idle. I do that then I don't have as many problems cause Vue willl let go of the processor a bit if I go check my mail. The biggest problem with rendering such a large size is the swap file can consume your entire c drive before it finnishes cause it will only get resized when it'x completly finnished. We need tile rendering. The other thing I do is hide everything so like make sure all the views are on hidden layers then when you check it from the screen saver it don't have to try to update all the wire frame views in the background. Just forget it exists and it will render......
