[Zengineer]

Hello all,

First post. Forgive me if this is in the wrong place.

I recently had my FPS drop considerably. After doing some research one of the suggestions I've found is not animating water/magma. However none of these threads, not even the wiki, mentions how to do it. So what do I have to do? Any other FPS increasing suggestions would be good too.

Are water and magma shown as numbers indicating the depth? If so:
Change [SHOW_FLOW_AMOUNTS:YES] to [SHOW_FLOW_AMOUNTS:NO]
in data/init/d_init.ini in your DF folder.

Though displaying the flow amounts doesn't seem like it would eat up FPS, it's usually the calculations themselves that do that.

Regarding the water thing, I think what you mean, Zengineer, is not stopping the animation (which AFAIK has little to no impact on FPS) but stopping water movement altogether.

So, the way I understand it, water in rivers and brooks flows from source to exit on the embark site, but, in their un-channeled state the water doesn't actually move tiles (its an abstracted river flow, perhaps?).  But once you breach the river the game has to start calculating where the water goes based on its fluid pressure mechanics.  This is what eats up FPS.  To save FPS then, don't cut into rivers (but what's the point, eh?) or try to stop falling/flowing water as much as possible.

Check out the wiki:

But there are lots of other ways to improve FPS (and potentially bigger problems), so check out the wiki...
