@matrix @nekojanai Maybe not. When I tried playing Cities Skylines on Linux and constantly ran out of my 16GB RAM*, I decided to look into forums for a solution. Some people were running out of memory at 24 or 32GB. Eventually, a developer showed up and explained that "memory is handled different in Linux", i.e.: we know; won't fix.
So they could very well know and maybe you can even find a workaround or find a time table for when that might be fixed.
Even the horrendous NVIDIA/Kwin memory leak got fixed! I was already prepared to live my life with it for years.
*on Windows the same save used ~900MB of RAM.
