High memory usage on Linux?

[mullagain]

First I want to say that I love this game and I am able to manage. I would just like to bring this up so that it can hopefully get fixed eventually. Also, I could be totally wrong here, just wanted to have the conversation and see if others are experiencing the same problems.

Both my friend and I are having the same issue with our respective machines. When quality settings are high memory usage goes through the roof. I have a fairly large swap setup for hibernation and eventually all my ram is consumed and performance starts to get bad because of swapping.

Here is what I have noticed.

• When my settings are on ultra the games use about ~70%  of my ram but swaps. If swap is disabled the system runs out of memory.
  
• When I logout of the game, the memory usage is still in the 70%+ range. Even just setting in the menu.
  
• I have tested on windows as well and memory usage never goes above 7.5Gb (never pages).
  
• Lower settings help, but eventually all ram is consumed.
  
• Swapping is the only thing keeping the system from crashing.
  
• GPU Memory sets at around 5/8GB
  
• GPU usage is at around 80%.
  

Just loaded in on ultra settings:

When I logout of the game, the memory usage is still in the 70%+ range. Even just setting in the menu.

This is a known issue. You need to quit to desktop to release the memory from a played game. If you

re-start a save without quitting to desktop, you can use up all your ram.

Also, post your log file from the game to pastebin and link here. There may be other clues in there.

Thanks for the info. I updated this to reflect your comment. I will add the game logs asap.
