32bit application programs (freespace2, office, paint) can run in x64 OS's.
32bit drivers (graphics, sound, etc.) can not run on x64 OS's.
Since x64 OSs allow you to have an ungodly amount of ram, i may want to direct you to this thread: http://www.hard-light.net/forums/index.php/topic,52777.0.html
Yeah. The only reason I want 64-bit Vista is because I am ordering +2GB of RAM for a total of 4gb, which 32-bit Vista cant take advantage of. The 64-bit DVD arrived yesterday, the RAM is arriving from Newegg today.
Thanks for the link.
i think 32 bit has come about as far as it can. most cpus out there are now 64 bit and the typical amount of memory in a system is on the rise. add that to video cards with more and more memory (it counts up to the 4gb limit) upwards to a gig. that means youre pretty much capped at 3gb memory.
i dont remember doubling the bits ever taking this long in the past. the moves from 8 to 16 pretty much happened overnight, mainly because of the simple operating systems in use at the time, and 16 to 32 moved pretty quickly because windows NT4/95 was actually an improvement over win3.1/dos. now with a ton of microsoft ****ups piling up over the last 1.3 decades, culminating in an operating system nobody wants to use, and still they offer a 32 bit version of it. they could have saved everybody a ton of grief by making vista 64 bit only. then hardware manufacturers would have been forced to get their act together and prioritize 64 bit over the older technology.
all this means is were gonna have to wait till the low end computer users get pissed off because they don't have enough memory to run newer software before 64 bit truly takes off and makes 32 bit a thing of the past (save running old software of course).
