If you look at the grandstand alone you see some of the most obvious issues with the rF2 graphics. -The roof is way to bright because there is no ambient occlusion. It's not a problem of the engine (ao is a performance killer), the modder should simply add an ao map. -The crowd billboards are way to bright. The sun comes from the right side and most of the people on the grandstand should be in shadow, but billboards (tree billboards too) don't receive shadows. -The saturation of the textures is all over the place. This may look ok in rF1 but hdr multiplies these differences and it looks like a cartoon. Here is a photoshoped version of the same picture. Added AO to the roof, darkened the crowd, reduced the saturation.
