Game Freezing

I’m having a problem playing some games on linux not all but this is second one. God of War for instance. After few minutes of playing it crashes. If launch steam from terminal I see this error:

GLib-GObject-CRITICAL **: g_object_unref: assertion ‘G_IS_OBJECT (object)’ failed

same for nvidia-settings in terminal. I can’t figure out what causes it. Help :-(
