When I had an 8800 GTS 320mb and I enabled Anti-aliasing in Dirt 1 at 1920x1080 2xAA, the game was a slideshow. I am talking 2-3 fps. Disabling AA with everything else intact resulted in 20-25 fps or so iirc. I then realized I have a VRAM limitation and upgraded to the 4890 1GB. If a serious VRAM limitation actually exists, then the game is unplayable and/or the performance hit is very large. Those benchmarks do not indicate anything of the sort for the GTX570.

A VRAM limitation would cut the performance by 2-3x (8800 GTS 320 vs. 640mb):

OR make the game completely unplayable (i.e., slideshow), as I experienced in Dirt 1 with 8800 GTS 320.

Shogun 2 exhibits this situation: http://www.computerbase.de/artikel/grafikkarten/2011/test-19-grafikkarten/24/#abschnitt_shogun_2

Perhaps the game engine dynamically pre-loads higher quality textures on a 2GB VRAM card. But I am not a programmer so I can't comment on the technical details of this. If the game actually required more than 1GB of VRAM, I would expect at least a very large performance hit in FPS.

Having said that, since this is still a BETA and we might get higher quality settings/textures under Ultra in the final release, perhaps the 1GB VRAM limitation will become real.

hey, i have some questions...
well the thing is, a user in a brazillian forum was talking about that bf3 works similar to a server app. it likes cores and memory acess.

anyone knows if a triple/quad channel improve something?

oh well, writing this made me wonder...
overclocking the L3 caches from the phenoms throght nb-overclok, may give good results too

I would venture to say memory latency is more important than throughput. The game itself actually doesn't use very much system memory. And for the most part, once a level is loaded, the memory is mostly static.

The game is multi-threaded well. So it can use 4-6 cores quite well. Unlike older games that were mostly single threaded with maybe some audio stuff thrown off on a second core.

I received my GTX580 3GB card today. After playing for a couple hours today on ultra settings and 1920x1200 I can say gpu-z measured a max memory usage of.... 1812MB.

If you get a chance, try out Caspian Border. Maybe the memory usage will be higher in that map...

1.1gig on my GTX580 1.5gig card, on caspian border.

The FPS is all over the place though on caspian. but its smooth as butter.

I run on slightly older hardware though, Core 2 quad 2.93ghz, 8gigs of ddr2 ram. Waiting on SB-E to upgrade rest of system.

I might go SLI GTX580 eventually for kicks.

for Ultra settings and 4x AA at 1920? that does not jive with the rest of what people are getting. heck I can hit more than that at 1280x960.

Appears a 1.5gb gtx580 is all you need then.

That is good news cause that's what i will go with over the 3gb model.

Unless a 6970 can do ultra 1920x1080 and with in 3fps of a gtx580 then perhaps i will go that route.

285.38 after i removed the BF3 beta the drivers caused random reboots and artifacting in bc2 that didn't go away till i reverted back to 266.58 with 280.26 fixing my reboot issue.

Such a shame perhaps its cause this is such a old card and the newer drivers work best with the 500 series?

Default settings, except AA. Most people turn that off anyways. Ansio is at 16x though. 1900x1200

So far I have seen 2 3gb gtx580 in sli and surround using 2.7gb of video memory

A single gtx580 3gb using 1.8gb of memory.

A single gtx480 using 1.45gb of memory (groover)

A single gtx570 using 1.2gb of memory at 1900x1080 ultra
A 6950 2gb using more than 1gb at 1900x1080p ultra settings vs a 6950 1gb at 1080p and the 1gb 6950 not dropping into the teens in fps.

@ Tviceman, yes you are correct, BF3 uses memory when and where it needs it but is seems unless your trying to run @ 1900x1200 ultra setting 4xaa with a card under 1gb you will be fine.

Unless I'm mistaken the only 1gb cards that can get over 30 fps minimum @ 1080p ultra settings 4xaa are highly overclocked gtx560's or 6950's 1gb cards. Even that is questionable.

Using x6 @ 4ghz with SLI 470s @ 775/1900 and memory usage is ~1220ish, Ultra textures, high everything but i think medium post process AA or something. Game runs silky smooth 50~80fps (GPUs around ~60-70%) upto around 100 (GPUs are ~90% used).

I'm hoping to build a 2600k rig in december to get a bit faster gaming and overall system that is "officially" SLI capable so I can stop messing around with slipatch and modded drivers lol.

The Caspian maps, servers are available to everyone now. I'm getting about 10% less fps there. Running all High preset, shows 890meg of ram, sli gpu% was near maxed. Never went below 65 fps, but never see the fps go as high as the other map. More is going on with that part of the game for sure.

On Caspian my vram usage ticked up to 1934MB max after playing for a couple hours.

I didn't check with fraps but I did jump in play with them and it felt better.

God, every time I played beta or seen in game video I just cringe. It looks nothing like those videos.

If EA doesn't deliver on graphics it wont be good.

no kidding. the actul game was not impressive looking at all. and if those ugly ass sandbags are in the final game I will do some super bitching. lol, I may even use them for my avatar.
