Does anyone know what settings each preset represents? Where can that be found? For instance what is added when you switch from Very Good to Extreme. My 560Ti takes a big hit on Extreme but to be honest it looks the same as Very Good. What's going on?

I can't tell different between high/very high but extreme gets masssive performance drop for me. I was able to play hardcoe on demo but can't do extreme

lol, dont have the word "explained" in the title because it makes it seem like you'll explain why we have only these presets.
