Cities: Skylines (Steam) - Landscaping / terraforming - extreme lag / stuttering/slow simulation on most of the unlocked tiles

[Pinco_Pallino]

Describe your issue
Landscaping / terraforming - extreme lag / stuttering on most of the unlocked tiles

What is your game version?
2022.14

What expansions do you have installed?
After Dark, Snowfall, Natural Disasters, Mass Transit, Green Cities, Parklife, Industries, Campus, Sunset Harbor, Airports

What mods are you using?
Relight and some other visual mods. All have been disabled and uninstalled but problem persists

Please explain your issue is in as much detail as possible.
I'm playing on Tropical Pass with 6-7 tiles unlocked and population is ~40k.
Whenever I start terraforming somewhere on the map, the simulation slows down to a crawl. This behavior is a bit inconsistent though, as I'm able to terraform properly without lag in one of the tiles (it has some oil industry and quite a bustling community of around 13k sims and plenty of lovely trees) but none of the others. I've tested terraforming in undeveloped areas but it lags painfully as well.

Can you replicate the issue? If yes, please explain how you did it.
Terraform anywhere in the city, try along the highway or over at the ore industry. By the oil industry it works fine

Do you have an old saved game before this started happening? You mention you unsubscribed a lot of workshop and I fear you removed something the game needed to operate properly.

Just revert to the old saved game and "subscribe all", then "enable all" and exit the game and restart it to make sure the mods are properly activated to the game.

Hopefully on launch it will work fine.

Otherwise, you may need to start anew, or just live with the slow landscaping and continue on?

Personally I'd start anew. There is no telling what other underlying issue may pop up later in the game. Luckily it is a relatively small city.

I wish you luck.

i just unsubscribed to try to troubleshoot, the issues started without me changing anything mod related at all.
I've started another game and hoping it doesn't happen again

Except mods can get updated daily, so you can get issues at any time. That is just part of the hazards of using the workshop. One day it breaks, the next it works, then the follow day, it's broken again.

If your next city works with the existing mods, it could just be a corrupt saved game.
