Sometimes my arma 3 would just freeze at the logo screen, after it fill up at around 300MB of memory. But if i launch it directly from the ARMA 3 root folder (without any parameters) it would still work sometimes. And also i can start arma 3 without issues with the Breaking Point mod (maybe because it replaced the whole splash screen?)
PS: I didn't use modded malloc or the registry tweaks {F25472} {F25473}
