Running build 0.16.1389. RimWorld failed to save map after running out of RAM again, on same map. Same memory usage pattern, starting at 1.6GB, but no hard crash this time, just an in-game dialogue. Ram usage at that time: 3609.5 MB

Code Select Expand

Exception while saving map: System.OutOfMemoryException: Out of memory

Full Output_log.txt included.

I am able to load and save (be it with lag) on my laptop 4 GB ram...

You won't reproduce the bug by simply opening and saving the map. The bug happens after approximately 1-2 hours of play as Rimworld.exe ram usage steadily increases.

OK, I reloaded the save (using today's build) and played for a couple more hours. The game failed to save, though this time in a slightly different manner than the first time.

Yesterday, I received an in-game dialogue stating that there was insufficient memory to save the game, but the game itself never crashed outright. This happened at 3.5 GB as reported by TaskManager.

Today, after playing for a couple hours, the game crashed with the message "Too many heap sections" or something to that effect during a save. This happened at about 3.3GB of memory usage as reported by TaskManager. Looking over the saves, it appears that the last one is corrupted.

I monitored ram usage during play and noticed a steady increase from 1.5GB on first load all the way up to 3.3GB. At no point did ram decrease appreciably, even when reloading a slightly older map. Only restarting RimWorld clears memory usage.

I am running Windows 10 64-bit with 32 GB of memory, and i7-3770K, and a GTX-770. Game resolution was set to 3840x2160 (which keeps resetting to 2560x1440 any time I load a save, I might add) with UI scaling of 1.5 and "Run in background" enabled.

After playing for a couple of hours, RimWorld runs out of memory (Task manager reports 3.5 GB). Faction is 2 years old, spread across two colonies, with a total of 11 colonists, 6 animals, and 2 colonies. Map size is 300x300 and world coverage is et to 30%.

The game doesn't crash outright, but it throws an error when I try to save.

No mods, obviously. Build 0.16.1387. My system is 64-bit with 32 GB of memory.

Edit: I reloaded the last save and monitored memory usage. It seemed to start out at 2GB, but increase up to 2.9GB over the course of an hour. I'll have to test it out more tomorrow. The issue may be a memory leak and not to do with colony size.

I'm perfectly fine with the pace of the pawns and day/night cycles, but I think progression could be stretched out in some ways to make colony development last longer. There's a transition point after about 1.5 years were you stop doing new things and start doing more of the same, just making the colony bigger, and this is boring IMO. Pretty simple balance tweaks:

• Slight decrease in construction speed
• More locked tech/research tiers, and/or longer research time
• Slight decrease in mean time between negative events and colonists joining
