[0.18.31] FPS/UPS Drop of 18.30 Savegame (wave defense)

Post by Alt3Rn4te »

Hello there,

Issue on version 0.18.31.

I am facing huge FPS/UPS drops in this savegame, created yesterday out of version 18.30.
I downgraded back to 18.30 and it's running fine again, around 60 FPS/UPS.
Going back up to version 18.31 it's causing my FPS/UPS to drop instantly to ~0.4.

Specs:
AMD Ryzen 5 2600
nVidia GeForce 1660
16 GB RAM
SSD
Win10 Pro

Hope this helps.
Regards.

There is huge load near Lua doing pathfinder requests. Klonan says it is should fix itself after config migration finishes and so it is not a bug.

its just a config changed migration to make sure the map is valid
For now i will move this to Not a bug, but because for me it migrates already like 15 minutes or more, i will ask him to look at this just in case.

-- edit:
It will stay in bug reports because this is really too slow.

Sadly it's not catching itself up after 30 seconds.

As I mentioned, on 18.30 it is really running well. It has to be something within the patch.

Well, issue is with script within save file itself, running that save file in 0.18.31 has the same effect as running in 0.18.30 with any extra mod enabled: will run configuration changed routine that is doing a lot of pathfinder requests.

Thanks for the report,

I added some rate limiting to the path requests, so it will prevent the massive script time usage spent on pathing calls when the pathfinder is busy.

Here is a save game with the updated script:

Please let me know if it works alright

Edit: We even get attacked again after ~150 Days of silence.
