64bit Systems are up to 6 years old, it's time to get some 64bit support nevertheless |
if you are on a 32 bit OS then demanding a 64 bit application will do nothing for you. since your system cannot alocate more than 4 gb of ram (actually more like 3.5gb with a single gpu or 3 gb with SLI) and the fact that windows 7 or vista enjoys gobbling up at least 1 gig of ram with "nothing" running that usually leaves you a max of 2.5gb of available ram for a game. if you run win xp 32 bit then you have another 500 megs of ram so the total goes up to 3 gb.
if the game starts chewing past your available ram then it will be using the hard drive's swap file or crashing running out of memory. a 64 bit executable won't save you from this.
32 bits can address up to 4 gigs of ram. that is more than enough for this game and any game out there. what you need to do is upgrade to a 64 bit OS and have at least 6 gigs of ram on the system itself and you will not have any issues with ram usage in the game. 64 bit does not mean the game or executable runs faster or you get more fps.
