it's NOT worse than a disabled mesh, lol. you are incurring the cost of a few extra polygons, but as a tradeoff you have far less drawcalls to deal with.
your GPU can easily push millions of tris, drawcalls are going to be way more expensive and drawcalls are the actual thing that you should be optimizing first and foremost. as long as you stay under 70k polys it really isn't gonna matter if those polys are always on.
