How to make LARGE line of sight blockers?

I am trying to cut down on pathing/line of sight blockers in my very large map to reduce lag.

No matter what I try, Line of sight blockers, with art - occlusion height set to some high value so that they work, will not block more than a single small area around the center of the destructible.

Changing the pathing texture of the destructible does nothing, the pathing texture seems to be irrelevant for what vision is blocked.

Setting Art - Fat Line of sight to either true or false does nothing. Setting it to true causes the destructible to block zero vision at all!

I am using gigantic 32x2/2x32 pathing blockers with custom pathing textures in my map to save on space, and would like to do the same with line of sight blockers rather than having to place 10 million tiny line of sight blockers which cause lag and increase the amount of time needed to save and load the map. Large destructible quantities massively lag the map.

Suggestions?
 
When I experimented with sight blocker destructibles, it seems like sight in Warcraft 3 works in "cells" the size of the standard trees. If the center of a blocker is within one of those "cells", it will block sight for units out side of that cell. Also sight is updated ~1-2 times per second.

If I'm correct about this, it's not possible to create large blockers.

I never experimented with buildings. They might behave differently.

Note that because of the bigger "cells", sight will not be blocked where you expect all the time, meaning that you can see through walls if you have a wall of blockers in some cases.
 
Isn't the Occlusion Height determines the vision blocking?
Yes, in the way that if the height is fairly low and you stand one cliff-level up or two, it doesn't block vision (you can see "over" the blocker).
With a 9999 occlusion height, it DOES block vision even when standing on higher cliff-levels.

Edit: Also, with 0 occlusion height, it doesn't block at all
