Line and points are very light. My pos 6150 LE has no problem drawing a few thousand lines to the screen at 60+fps. Points are even less expensive. As to exactly how it will affect one computer I can't say. I would guess the toll would be extremely slight.
Mapmodels are another story. I've tested multiple rain mapmodels and they usually ate 4-5fps, though they were not animated at the time. It's not the sort of thing you would plaster a map with; I intended it for sparse usage.
Edit: "few thousand lines" not "few hundred thousand".
