TL;DR: I went from 10 minute load times to < 1 minute.
With all of the region packs, my load times are now almost 10 minutes to startup the game running off a dedicated fast SSD drive. Remember, these region packs are mods and mods/logs sit in your system user profile, not where you've installed the game.
Using Steam launch options (see attached), I dropped my logging to ERROR and my load time went from almost 9 minutes to under 1 minute. So my launch options are now: "D:\Games\Steam\steamapps\common\Cities Skylines II\Cities2.exe" %command% --logsEffectiveness=ERROR
This does the following:
- Loads directly into the game, skipping the launcher (Note my game is installed on my "D" drive)
- Lowers logging to "ERROR" level
Setting logging to "WARN" was around 3 minutes. Obviously, diving into the logs to see if there's anything I can resolve might be a good idea, but can I just play the game and not be their QA team? Especially if I'm trying new maps or mods and needing to restart, 10 minute load times are a deal breaker. My logs are almost entirely issues with region pack assets.
You can find the logs in: "C:\Users\%USERNAME%\AppData\LocalLow\Colossal Order\Cities Skylines II\Logs"
Side note: Either use the Skyve button in options -> folder settings to move your profile or follow these instructions:
1. Move the "Cities Skylines II" folder in C:\Users\%USERNAME%\AppData\LocalLow\Colossal Order" to another drive
2. Run cmd, type in the following command: mklink /J "C:\Users\%USERNAME%\AppData\LocalLow\Colossal Order\Cities Skylines II" "the location you moved the folder to".
This way you'll create a "shortcut" for the folder, but the actual files are not taking precious storage on the C drive```
