Well, I will say this, quick save crashes happen only after a while in game. If the quicksave cannot attribute to the memory leak directly then it must simply be that quicksaving utilizes some resources that require more at a time when the memory leak degradation has reached the tipping point and is ready to crash. The quicksave simply pulls resources that are not avilable and this is why I see a crash at those times.
Quicksaving early in a session, right after game startup is fairly stable. It's only when the system gets bogged down with memory problems does quicksave become an issue. I can even tell it is getting close to crashing after awhile and I know that my quicksave might cause the game to crash...I always press quicksave and hope I can skate by. I am just saying that I believe if the memory leak was not an issue that quick saving would not crash the game.
I will say this, that it makes me quit in disgust quite often when I lose progress right when I wanted to save it. Replaying a difficult or tedious battle is not much fun because of a crash. I guess at somepoint the memory problems will go away, and I imagine quicksaving will also be fixed. The auto save AFTER a turn thing is bad imo...defeats the whole purpose almost.
BTW I have a 4870 1 GB card, I7 920 quad core, 6 gigs rams, Windows Vista....latest drivers.
