With the way the HDR is set I think "Cold" looks like it has way to much image sharpening on it. Maybe if I could enable FSAA it'd look better?Looks great, have played the same way myself. You should have chosen cool under the shading effects, gives it a much more realistic look instead of a shiny, colourful cartoon.
"Paradise" has the most HDR, everything seems to cast a glow. I think "Improved" and "Default" look the best. But it's hard to tell in these screen shots... With JPG compression and scaling the difference between images 1, 3 & 4 is very minimal, it seems much more in game.
