If not, is it time?

The claim: I play what's fun.
The truth: Video games aren't entertaining enough, I must chide others for choosing to play something I won't.

Please rephrase your first question.

If however you mean a 64-bit operating system (which is what I'm assuming), then no. And no.

We are right on the edge. For the most part, 32bit will give you minimum settings these days.

The executables are still 32bit but they get access to 4 gigs of RAM and unlimited VRAM.
So as long as a game doesn't need more than 4 gigs of RAM there is no reason to go 64bit yet.

However, an operating system at 32bit has a maximum of 4 gigs memory total, thats VRAM and system RAM combined. And subtract 512mb of kernel space(wasted memory) and you end up with 3.5 gigs maximum assuming you don't have a video card, if you do, VRAM is subtracted from the system memory. A 1 gig card will leave you with 2.5-3 gigs of RAM. A 3 gig 680 would leave you with less than a gig of system ram. You can't run a game in that little space.


64bit OSs emulate 32bit address spaces for 32bit programs. So each program gets 4 gigs of addressable memory space.

I think I learned more in this post than I did in a whole semester of CompSci.

No wonder my PC can't play s***.

No wonder my PC is behaving like crap, I have 3gb System and my GPU has 2gb, i'm on W7x86.

Also, wasnt Watch_Dogs the first game to *require* a 64bits? or I'm confusing stuff?

The second "no" seems to be implying that we should still stick to 32-bit OS's. If you were going to buy Win7 or later, why wouldn't you get the 64-bit version? The only reason I can think of is 16-bit compatibility, which you can get with DOSBox, and I don't think 32-bit Win7 works with 16-bit games anyway.

I've seen a few Alphas/Betas that required 64 bit but with a 32bit final release, if only as an option. Watch dogs is the only one I know of that will be 64 bit only.

Be careful on the X86 stuff, X64 is short for X86_64, don't reinstall for nothing.

Doesn't X-Rebirth require x64? It's hard to tell why since performance sucks so much.

From what I heard its a 32bit exe.
However, the graphics card requirements puts it over the limit of a 32bit OS, so realistically you'd want a 64 bit system.
