Why
This Mod Just Remove Some inneed Grasses..Not Whole Grass
Because you will be able to see players in the open while in their screen they are surrounded by grass
I think you didn't understand what the mod does.
Some plants, bushes and grass in single player don't exist in SA-MP. SA-MP dev team took this decision to avoid crashes and sync difficulties.
What this mod does, and what you can see in the video, is add that vegetation back to SA-MP, so it looks just like single player. In short: mod off = no grass; mod on = grass
Considering this, I don't think it gives any advantage, since it's about adding textures, not about removing them. Correct me if I'm wrong
