Hi All,
I ran across this spreadsheet linked to a post in the official forums. Zonflux created it to find the settings that limited memory related crashes for him. It may help others. See here: https://docs.google.com/spreadsheets/d/1gEF_iN5Eo3j4L1RaMCEH-9rF3aNBA7IBZLxsSXfMHnw/edit#gid=1240609003 .
I've evaluated this. Interestingly, I was mostly using the same settings. These do seem to limit, but not eliminate, some of the game crashes.
