This [url]http://www.techpowerup.com/forums/showthread.php?t=112556[/URL] application may be of use to people. It makes 32-bit .EXE's large address aware.
Point the program to your RO2 .EXE. I enabled it for RO2 - used to crash on Barracks within 10mins of play now no crashes at all. I also lowered my Shadows settings from Ultra to High.
Good idea - and I remember doing this with Arma 2 before the devs made it large address aware.
But... do we know how VAC will view this?
