[2020] RAM overload

What's the size of your pagefile? Have you checked for the latest drivers for everything? How does the game run if you add the launch options -noWorkshop and -disableMods to Steam?

How To Set Launch Options

• Right-click on the game title under the Library in Steam and select Properties.
  
• Under the General tab click the Set launch options... button.
  
• Enter the launch options you wish to apply (be sure to separate each code with a space) and click OK. Should look like this:
  -noWorkshop -disableMods
• Close the game's Properties window and launch the game.

The only difference between the two Loading Screen mods is that Test has a bit more logging, so it's easier for the modder to troubleshoot issues. I recommend just using the normal version. The most important thing is to only have one of them subscribed.

Sounds like we're hunting for a mod. I'd be happy to take a look at your mods and see if I can help narrow it down. The easiest way for me to do that is to have a look at your output_log.txt.

Here's where to find it. To easily find the local files for the game, right click your game in the Steam library, select Properties, go to the Local Files tab and select Browse local files.

\SteamApps\common\Cities_Skylines\Cities_Data\output_log.txt


As we can't attach files here on Steam, you will need to upload the file somewhere else. Here's a few sites you can upload it to, which do not require you to sign up first:

https://uploadfiles.io/ - free, no sign-up, can handle large log files
https://paste.ee/ - fast, no sign-up required (some log files will be too large for it though)
https://zerobin.net/ - bit clunky, but can handle huge files, no sign-up required

Do you have a program to check the temperatures of your graphics card? If not then you can use a free one like speccy to check it. The graphics card is definitely having problems, which it shouldn't with those launch options in. :/
