Ah, didn't notice that part yet, still you asked why go to v1.07beta, on which I replied To get OnTopic, anyone of you tried to run the game with added parameter: -maxmem=768 ?
If I don't use that setting in v1.07.5157, then my game crashes with memory mapping error after a while aswell, it just doesn't pull down my whole system
I will give this a go - Who knows, it might even work?!?! great game, poor use of pc technology. OFP was wicked as well, but this is so unrealiable and slow it just kills me, sometimes literally in game!
