Rubbish.
2 x GTX 690s quad sli @1600p maxed out running BF3 use 1.8gb per gpu.
lol, why does everything have to turn to AMD vs nVidia. He never even began to talk down those lines. It was a simple point that if you have less memory, you can in theory overclock it better.
This has been proven by a few people with 2GB/4GB 670/680s and it makes sense as to why this is so.
I'm really quite confused as to how the conversation has ended up where it is. Perhaps because Matt and you got super defensive about AMD when really there was no need to.

do stop it - a long thread (and multiple on various forums) - if a card has more than 2GB then the game will use it where possible.
a gtx 690 is 2 x 2GB cards together in SLI on 1 board , they don't share the vram pool (ie 1 4GB lump)
Stop what? You are making it seem like the game needs more than 2GB @ 1080P with max settings or you are just baiting, in which case I will report your post.
I happily played BF3 on full ultra with 2GB 680's at 5760x1080 with no issues, so I urge you to think before you type in future.
What will having 3gb of vram do in bf3 that 2gb wont ? more fps = no , faster loading times = no.
So the question is what use is extra vram at 1080p res ? = none
no I said the game can use more than 2GB at max settings at 1080p , you said it wont and I showed where it can and does.
if you want to report my post then please go ahead - I have posted something factual about 2GB cards.
He didn't pass it off as 'in theory' though. He said "More than 2GB on a single card is a mistake, not only do you have to pay for the extra vram, it also hinders performance by making overclocking more difficult."
Its been proven, according to one Guru3d benchmark supposedly on Nvidia cards, not AMD which was my whole point. The problem was Kap made a blanket statement, which i queried and when he explained what his opinion was based on, i disagreed, as have others.
I don't see that as getting defensive as you like to put it, i just see that as a person stating an opinion as fact which a few of us disagreed with, rightly or wrongly.
A forum is for discussion and opinions is it not?
But you are wrong. If the game uses less than 2GB at 5760x1080, how can it use more at 1080P?
You are confusing storing (caching) VRAM with using.
Yes I am aware of that hence my reply which I quoted below.
Two GTX 690s = 4 GPUs each GPU will use 1.8gb of vram maxing BF3 @1600p
If I were to disable 3 of the 4 GPUs, the single remaining GPU maxing BF3 @1600p would still be using 1.8gbs of vram
With SLI the vram on all GPUs need to be all doing the same thing with the same data.
no im not wrong , but I`ll spell it out for you:
I said it can (not will) use more than 2GB vram - I didn't say what for, but that link (and many others) show it does go above 2GB ram usage , when its available. And as rusty said its going to be for caching - but on a 3GB AMD card it uses more than the 1.8 your getting , since it has more space to work with.
and im not confusing anything - what do you think vram is used for? storing textures , pre and post processing before being sent to the ramdac for display

Ok then. Does it NEED more than 2GB?

Please check the memory usage.

proves EXACTLY what I said - where the resources are available - BF3 *CAN* use more than 2GB... you are `limited` to 2GB per gpu , of which you have 2 per GTX 690 (it works as a 2GB card).
toms did a review and the 7970 was using pretty much all 3GB , although IIRC BF3 maxes out at about 3.5GB ram usage WHERE AVAILABLE.
So how much do you think a Titan will use and at what resolution.
