I used the tool to set the required privilege (AddLockMemoryPrivilege root) root is my PC account name which is a Administrator account. It said it was applied and told me to restart. I did then I added the start up parameter in steam (-malloc=tbbmalloc) I then ran Arma 3 as admin played a bit then checked my Arma 3 directory for the log file and it's named malloc_1628.txt http://pastebin.com/68WG8yfS I also ran steam as Admin before I ran the game.
I have 8gb of ram installed. I am obviously doing something wrong and do not know what. Can you help me? :)
thanks.
