TF2 – Engine out of memory

macosteam-fortress-2technical-issues

Whenever I join a multiplayer game in Team Fortress 2, I can play for about a minute, and after that I get an error message and the game crashes.

The error message is: Engine Error: Out of memory

This shouldn't be happening – I have a good 8GB of RAM.

I've turned a few advanced video settings to LOW, including:

  • Shader detail
  • Color correction is DISABLED
  • Water detail is Simple reflections

Any fixes?

Reference:

  • 27" iMac
  • Running OS X 10.11 El Capitan
  • 8GB RAM
  • Intel Core i5, 3.2 GHz Quad-core

While it's not exactly a "fix" (since 8GB of RAM should be plenty to play TF2, as you mentioned), try turning all the graphics settings down to "Low" or "Disabled". A lot of other Mac users are running into out-of-memory issues when playing TF2 recently, and it seems that turning down all the graphics settings to the lowest values has helped a significant number of them.
