Massive lag from fires.

[gerb0rken]

I'm running v0.9.727 with no mods.

Whenever there's a fire visible on-screen, the framerate drops to 1 or 2 fps. Fire from an incendiary mortar caused it in one game, a crashing AI pod caused it in another.

The weird thing is that the usual fire graphic doesn't appear -- I get a glow where the fire should be, and sparks, but no fire image.

If I adjust the viewing area so that the fire's not visible, my framerate immediately returns to normal.

I'm playing with a large map (300x300) instead of the default size, which is the only difference from the 'standard' game I can think of.

Is there any way to fix this? Hoping to make it through a game without needing to manage a fire is sort of like hoping for a game where the pirates arrive with gifts of plasteel and gold instead of shivs for your kidneys. And eyes. And...

Weird, you're the second person reporting this problem this week.
Could you please post a save file and the world file where this is happening?

Sure thing, here you are: https://www.dropbox.com/s/v1jdpmagsgwkuft/RimWorld.rar?dl=0

A dry thunderstorm's just started and the fire's in the top right of the map.

Sorry for the double post -- I just loaded the game up to continue playing and got a huge error log, so I've uploaded it in case it's useful as well. https://www.dropbox.com/s/4371oeytkv9ed30/output_log.txt?dl=0

This is happening to me as well, and only as of yesterday.

These are my screenshots: http://i.imgur.com/kGwYrpp.png - http://i.imgur.com/zT5NYCU.png

Fire used to be a sprite, but now it's practically invisible except for the glow and the smoke, and it causes some EXTREME lag.

I attempted to create a new colony on my existing world and blow up some boom rats, and it's still like this.  I'll post again after creating a brand new world to see if that changes things.

EDIT: After creating a brand new world and a brand new colony, fires are back to normal.  I'll see if I can make a video.  http://i.imgur.com/n8ZCF1d.png

Here is a video detailing the differences in the fires being experienced by OP, myself, and others:

Thank you very much for reporting this and providing the savefiles. I've created a Mantis report: https://ludeon.com/mantis/view.php?id=1648.

I find this bug extremely weird, I've only managed to reproduce the problem using the world files you uploaded. Does anyone remember noticing this issue at the start of the colony?

[Jaldy]

Not for me.  It just appeared somewhere in my playthrough.

Locking as this is being addressed on Mantis. Thanks for reporting all.
