thanks but what about large address aware? is needed when is used d3d8.dll? cause LAA is probably important for clean gameplay or?

EDIT: when i put d3d8.dll game is loaded fully like always but LAA tool doesn't work... I'm testing my own traffic mod where is used 300(?) cars (edited in patcher.cfg) and game stuttering after 10 min of gaming.. i got steam version of game. And how much RAM is using Mafia with LAA tool?

please could anyone tell me how to use large address aware tool exactly?
