The game is not optimized to manage the client RAM.
When the game starts, about 2 GB of RAM is used. After a few hours the used ram grows to saturate and crush the game if no windows pagefile is set.
My PC is 16GB of RAM and I don't want to set a pagefile on my SSD for this game.
FIX THE GAME in order to FLUSH obsolete RAM data please. PS: tool like Ram Cleaner does't work.
