settings tweak help needed...

So now that the game doesn't freeze up... now I need to get my settings right... What's happening is every so often there is a brief freeze up, like in milliseconds, and then continues on. Obviously caused by my settings so... what should i tweak?

(not turning world detail down.... i like it high as the draw distance is too close at lower)
