Poll: If You Don’t Have 64-Bit Windows in 2013, You’ll be Missing Out

With the low price of RAM nowadays running 64bit with over 4gb is inexpensive anyway.
Or just download the ISO from a legitimate source and install via USB.
No, 64-bit addressing is slightly less efficient (due to pointer size increases). The whole point of 64-bit is being able to use more RAM. XP 32-bit was limited to 3.5 gig overall and 2 gig per process.
As I understand it, the issue is with increasing VRAM on GPU's
A 32bit OS can address 4GB of RAM. The 1GB or 2GB on the GPU is directly addressable so comes out of the 4GB system address budget.
I.e. with a 2GB card you may have only 1.5 - 1.8GB of Ram available to the OS. The remainder is in the system, but there are no remaining pointers to link to it.
As games required more and more textures to improve the appearance, bigger frame buffers are needed hence the move to 64bit OS and a probable requirement for 2GB frame buffer

fail. even though you quoted my post, you completed ignored this rather important part of it.
i know this has already been clarified in responses since but i felt the need to point it out since you missed it.

Not true,
My work machine (XP 32) has a 1GB GPU and 4GB ram, windows usable? 3.5GB.
Simulation machine I run FS9 has a 2GB GPU and also has 3.5GB usable IIRC.
From my googling 256MB of memory is used to transfer to and from GPUs.
Putting a 4GB GPU into a 32 bit machine doesn't mean you have 0 memory.

So it's only taken 9 years since Athlon64 for 64-bit to become standard?
Software is still so far behind hardware. Crysis (2007) was 64-bit and Crysis 2 and 3(2013) are 32-bit in a bizarre backwards step.
X3: TC and AP use 4Gb and could use a lot more if they were 64-bit. Battlefield 3 is said to use 3.5-4Gb somewhere on here.

No he is right windows can only see 3.5GB of system memory (GPU+RAM).
so as GPU Ram increses you can't address an increaseing amount of RAM
I doubt it would just address VRam thou.

32-bit is a new IE6.
Can only be a good thing.

Battlefield 3 does not run without constant crashing unless you have a 64 bit OS it needs at least 2.5Gb free Ram to work properly so if you have a 32 bit OS you need to either type a command line instruction to increase this or change your boot.ini for PAE if your GPU has more than 1GB VRam which this game needs.

I agree with what you say in that the "test" doesn't really show the full picture. But a few return points:
-Most games do have a 2GB limit yes. But some games will not use close to that amount so regardless of whether or not the limit is increased, if the game does not need it, it won't use it.
-This is true indeed. Which is why this sort of future proofing is needed. Later on in the UE4 development stage I think we're going to see games that demand systems that require more than 4GB memory so it is better to phase out 32-bit now while compatibility is not a problem (or at least phase it out for most PC gamers).
-See above.
-I didn't really know that so thank you for informing me. I guess it was a bit of a dumb conclusion to come to that a single number in task manager would paint a complete picture.
New consoles is going to help PC's push higher RAM usage, the only reason the games listed earlier used 1.5 max was because they were ports from a console with 512mb RAM. Next gen games will have 8GB to play with on Ps4 so the PC ports/versions will naively support much higher RAM which will help quite abit.
As for 32bit vs 64bit certain motherboards only support 32bit right? That'd be the main reason for some people being stuck on 32bit I imagine.

You're sort of right. It is dependant on what sockets the motherboard supports. If it can socket a 64-bit processor, it will support 32/64-bit OS, if it can only socket 32-bit processors, it can only support 32-bit OS.
A lot of sockets can house 64-bit processors of some sort anyway. 754, 939, AM2, AM2+, AM3, AM3+, FM2 from AMD and LGA 775, 1366, 1156, 1155, 2011 from Intel. I've probably missed out a few.

Consoles impact PC development, like it or not.
PS4 is x86.
Worth bearing in mind.
