nope, grass in that game does not count as the object.
The thing is simple... we can give you grass on a small map and you won't feel any problems and we can give you small map without a grass and also you won't feel a problem
on a big map you got problems not because a grass but because the size of the map overall...
Cmon how many of you -> example kwiatek -> cries about a grass now but in a past without a grass still complained that he cannot play on big maps like colorado / caliwood -.-?
Before grass i could play on colorado cuz i had 30-40 fps without drops (maybe sometimes), on caliwood... yep i couldn't play but now, when grass is on, i can't play even on warisland...
