High Memory usage shown in Task Manager (about 3GB)
Assigned, WishlistPublic


Is it normal that 32-bit application in 64-bit sytem can get around 3GB memory usage? It can be achieved in multiplayer playing around an hour. I just wonder if that could be the issue some people crashing out of memory. I haven't got myself a crash in this patch though the memory usage sounds bit high and it was like that in 1.48 also. Is it supposed to be like that? {F26876} {F26877}

3GB :D Why Arma cant use 8 GB ?

We're talking about 32-bit application. I've thought that 32-bit application could use only 2-2,2GB but is the real limit actually 3GB?

It can use up to approx 3.75GB in standard but its possible that arma can use more with such called "large memmory fields" but requires some tweaks on windows. This issues i see my self when playing with standard malloc of BI. Try to use "system" as a malloc (without ' " ').
To your question google : Large Memmory Aware Flag
