I will answer this for you man. The answer is never lol. In fact to prove the answer is never if you look at the forum or the help cats or even on raidical facebook page you will notice 1 thing. They have not even responded back to anyone asking the same question. Emails dont even get answered. I think the best idea is to ask for a refune. Trust me I my self enjoyed the game I did beat it also but this memory leak issue is why I might never buy another activision game as long as I live. They act as if they dont care about their consumer's when a game has this type of problem. So there I answered your question. Activision will never release a patch nor even consider working on one. They will not reply to this post so ya your wasting your time asking that lol.
