How do I Set Objects to a Lower Res?

Or at least that's what I think I want.

My character is too "in-detail", I can see each individual pixel he is made up of. I tried drawing him larger, and smaller. Samping is on linear, and I've trying turning down "downscaling" and whatever else. I'm sure there's a solution to my problem. Anyone?

Try making your sprite 2 times as big as you want it, then scale it to 0.5 in game.

This is how Zbrush does it's AA.

So if you want a 32x32 in game, make it 64x64 in your editor.

Hope that is what you wanted, my English skills are not so great.
