@Veltro, hi mate
I'm with you about landscape visual quality; I remember endless discussions a year ago about this comparing CloD to others sims (WoP ROF etc etc). I think nobody will tune the actual textures till the devs will open to 3d party.
About the well discussed before themes about sepia filter and the notorius 'green puke' filter of WoP, I would prefere those or any other hollywoodian post-prod effect to the actual cartoonish landscape (de gustibus
). BTW better any filter (fictional or not with the purpose of create an involving atmosphere) than a bad tentative of recreate a 'realistic' virtual reality.
