Auto Travel Slowdown

[Myfharad]

Describe the bug

I use auto travel alot when im playing cdda, and recently while I auto travel the game slows down a significant amount, and I know that sometimes it happens because of underground labs or alot of monsters. But recently its just been randomly slowing down, and even after Auto Travel is completed the game will continue to stay slowed until I reload.

Steps to reproduce

This has been a random problem I've been having and isn't easily repeatable since it just happens randomly. Though it only happens sometimes after Auto Traveling.

EDIT: I believe you need to traverse z-levels to speed encountering Auto Travel slowdowns.

Expected behavior

I expect the game not going into a weird slow down after auto travel is completed

Screenshots

EDIT: https://www.youtube.com/watch?v=QO4Iso4Igxw footage of the slowdown. Use the timestamps in the comments section to find out where the slowdown occurs.

Additional context

Removes Fungus and Ants is a mod I made that only prevents any Fungus or Ant map tiles from spawning into the game.

I'm not seeing any particular (anecdotal)slowdown, and a quick profile shows nothing crazy.

Same thing is happening to me, it only started after i updated my game.

Yeah its a very random thing that isnt easily repeatable, I'm going to see if I can get maybe a video of it happening? I know without context it just sounds like maybe im auto travelling over a labs, but im positive its happened to me where there are no labs, especially since the slowdown goes away after a quick reload of the game.

Does it look like this case?

There are pits or bridges nearby. Happens after a significant amount of play time (1-2 real hours). If you save and load, everything is normalized.

Maybe... but from what I've found out is that traversing z-levels seems to speed up encountering the auto travel slowdowns. So instead of it being a bridge problem in #71419 its instead a z-level oddity.

[Myfharad]

I was able to capture the slowdown on video. Like I mentioned before it was easier for me to encounter the slowdown after going up and down z-levels before auto traveling. It's uploading to YouTube and I'll post a link to it.

In the video you'll see that my character slows down after climbing a fire lookout tower, then attempting to auto travel. Im not sure how easy it is to see the slowdown, but I do reload so that anyone can compare the slowdown and non slowdown.

I have timestamps in the comments to find out where the slowdown happens, and to compare to a reloaded state.

F1 = debug menu

1. Create a default world and character
2. F1-m-rreveal map
3. Find the radio tower
4. Teleport to the tower and go to the stairs to the upper levels.
5. Do a save game
6. Establish clear weather: F1-m-w-3
7. Go up to the tower (level 6) and descend to the ground
8. Set auto-move to a distant tile (~10 global map tiles)
9. Go on a journey (kill monsters through the debug menu if you have to)
10. Pay attention to the speed of movement
11. When you reach your final destination, change the weather to fog: F1-m-w-6
12. Start auto-traveling in the opposite direction to the radio tower.
13. Pay attention to the speed of movement
14. Change the weather from clear to foggy and compare speeds along the same path.
15. Load the save.
16. Repeat steps 6...13. But change the weather order. Before climbing the tower: fog, after reaching the end point: clear.

UPD. Slowdown occurs when the weather changes. More precisely, when it does not match the weather, at the moment of climbing to the top of the tower.

I'm not sure this works with any weather pairs.

Just did it, and Yup its only when I change the weather on my way back to the radio tower does the game take a nosedive in performance and slows to almost a crawl.

I wasnt sure what you meant by the "speed" but just to reiterate, the in-game character speed stayed at 100 though, but the game itself ended up in incredible slowdown when auto travelling in weather that wasnt the same as the one on top of the radio tower.

I wasnt sure what you meant by the "speed" but just to reiterate

These are translation problems. Speed of movement in the sense of the speed at which the character moves across the screen. Perhaps it would have been better to use performance?

Its no problem! But like you said, its definitely the weather difference between the top of the tower and auto travelling that was causing incredible performance slowdown. Is it something that is being looked into?

[IdleSol]

I'm not sure. I haven't heard of such a problem. But perhaps the weather is not a cause, but a consequence.

We need to wait to see what more experienced people have to say.

[Brambor]

I am totally guessing it is related to lighting and caching some light maps. If so, not changing weather but day/night should work too, probably, if the character can see enough.

Also, mutating to something with more / less vision.

Edit: oh, the issue you linked is pretty much about that. Kudos to you, if it is correct!

I haven't noticed a decrease in performance when changing day and night.

Perception 20 and Full Night Vision.

@RenechCDDA

I apologize for the distraction.
Can you try to check the performance when doing the steps:

[SurFlurer]

I can /confirm this does happen. The main difference is caused by build_map_cache .

When foggy:

When clear:

[SurFlurer]

The main difference is caused by build_map_cache .

This function isn't called more frequently when weather changes ( otherwise it's lot easier to fix ), but it takes longer for a single call.

Don't know, will it help, but here is is pr with fog addition #64954
