Messing with settings

I was messing with light settings and graphics settings and stuff earlier, just to see what difference it made. I first was messing with windlight settings, or at least messing with the presets. I was quite surprised with all the various looks you can achieve, just by changing to another preset. Second up, I messed around with the graphics presets to see what effect they had. The difference was quite remarkable. Take there two shots as an example? I presume you can tell which was with everything on high and which was on low.

Wouldn't be nice to be able to wander round in ultra the whole time, eh?
