At first I thought it was a problem with Pure and its ppfilter but then I realized that Nords and other tracks look great and it's only with some of my favorite tracks that the environment looks washed out. I believe Pure lets you define custom adjustments for individual tracks, so I wonder what are the best settings to correct all the issues with these specific tracks. The main problem is that they lack a lot of contrast, but there are some items on the track that look very dark, almost black, which makes the whole even less realistic. Reducing the gamma or increasing the constrast in the ppfilter improves the look of these tracks a lot, but the interior of the car gets too dark.
