If you haven't set up a custom-sized pagefile (I recommend 32000 MB ) Windows might be adjusting the size of it on the fly. Unfortunately, it doesn't handle small changes well, which happens with Cities: Skylines.

Of course, there is no guarantee it's related to the pagefile, but we need the output_log.txt to determine what's happening as the game starts. You are very welcome to make a post on our official support forums and we'll have a look.

The output_log.txt can be found in the Cities_Data folder where the game is installed. The easiest way to find it is to right-click on the game in your Library, select Properties, find the tab Local Files and click Browse. Then just attach the log to a post on the forum.
