Thx for the input, but don't look to framerates. There was some apps in background
FPS will be very solid in this map, visibility is controlled with env_fog, only a 30-40% of terrain is rendered (but fog limit is hardly noticeable while playing, not in some of those shots). Only sprites will take some serious resources, to see vegetation like this you must specify cl_detaildist up to 4000. People with low systems won't see any sprite (except corn plants, those are env_sprites) and his framerates will be very good. My aim is to do a good landscape, but will be playable by everyone.
