@ ExoduSs, yes we can and we do.
Obviously the less polys you have the lighter your model will be...
On the end when it comes to graphic/visual effect it's day and night, this is why I have modified to 'full' models the grids/grates and the 'fence_chain_link' (this not yet committed to svn).
The thing is with planes only models is that the closer you get to the side of it the model tends to disappear, it's physically too thin to be seen.
My point is that single plane models should only be used as 'decals', something you stick against a structure, a wall, floor and so on.
Single plane model
Full 3D model
Please also note that nowadays in order to avoid the 'shoot through' issue we no longer use single plane models, even decals are made of 2 planes.
