I just installed a new Asus EAH4350 graphics card in my desktop. I have downloaded the new drivers and recently added another stick with 2GB memory in my machine for a total of 3GB. I still get game crashes with OUTOFMEMORY message. I think it might be linked to start up processes that run rampant even though I use procexp to help control them.
