Random FPS drop?
« on: January 16, 2011, 07:33:56 pm »
So Spring comes. I'm going along at 99-100FPS. The elven caravan comes, and I get a MASSIVE drop in FPS. Down to the high 20s,hovering around 28.

So I figure, okay, not a problem, the caravan was the cause, I'll buy nothing from it and it will leave.

The caravan left. The FPS drop didn't.

Getting quite angry* at this point, I use DFHack to spread magma all around the outside of my fort. Every surface tile is covered. The magma evaporates. No FPS increase.


*not really, but I needed an excuse to do this. >_>

I didn't discover or do anything that could lead to such a huge drop, from what I know. I am quite confused now.

Do you have any ghosts wandering around?

I...might? I made a few memorials, I can go make the rest.

Shouldn't have TOO many, though, maybe around 5 or 6 if everybody rose up and was all ghosty?

Are you on an Evil biome? It's possible that a large swarm of zombie crundles or something like that, and they're spewing miasma all over and eating your FPS that way.

Nope, it's not an evil biome.

I thought maybe I had a few ambushes waiting since I'm closed off from the outside until my military can learn to stop dying, but the magma should have taken care of them, right? Or is that not a factor when the enemies aren't visible yet?

There seems to be a somewhat random bug that causes FPS to drop dramatically due to ghosts. Sometimes, there's no problem with ghosts at all, but sometimes, only 1 ghost is enough to make your FPS bug out.

Okay, and I assume making the memorials solves this, since there are no more ghosts? Or does it stay crazy forever?

it would have absolutely taken care of them.

While adding magma to anything will make it dwarfy, adding the word "magma" to your post does not necessarily make it funny.

Have you tried saving and reloading?  It worked for me once after a bit of fun with glaciers and magma.  Steam-generation lagged up the game and even trying to make more steam didn't help.  A save and a reload and it was back to normal.

Saving and restarting seemed to work, actually. Didn't want to start playing until I'd had at least some idea of how to fix the problem, but if the problem goes away on its own I'm perfectly okay with that.

Are you playing on a laptop by any chance?

Yep, my laptop is faster (and better in general, specwise) than my desktop.

Which is pretty sad, now that I think about it. >_>

The reason I ask is that on my laptop (Lenovo 3000 N500, pretty old now), although it's fine at first, at some point the fans will kick in hardcore and the game (the whole system, in fact) will slow a crawl. As I've heard that laptops have problems with heating, I can only assume that the CPU reaches such a high temp that processing is throttled back (perhaps someone more tech savvy than I can explain better). Might be the same thing happening to you.

There doesn't seem to be any fix either - pausing the game for a while works, but only temporarily.

Eh, the fans do go on when playing but aren't really consistent with an FPS drop by any means.
