My PC handles every games well except this one, there seems to be a consistent problem of memory leak running the game, the progressive lag comes every half a hour or so playing a medium sized map with even a fairly rural town until I save, exit to planet and re-enter.
The problem persists throughout the patches.
I did only very simple testing using task manager, it seems the game was using lots of page files already after 30mins in game, my hdd is a sata2 with 32mb cache, it was not under heavy load. Then I checked the memory status, usage was well below 40% of 6134mb.
I doubt if this only happens on X64 systems. This makes the game hardly playable, for this reason I am not going to buy it.
