worried about 2g vram

[jamesriley94]

BF3 will use more RAM than it needs if available. There'll be no performance gains by adding more whatsoever, just monitoring programs can show that a game is 'using' more just because it's there

Sounds like rubbish to me

link me to a credible source

LOL. Why do you think games use more Vram when available? Do you think it's "Just because?" In fact why do you think games use Vram in the first place? This test can EASILY be done at home. Find a powerful GPU with 1gb of RAM and find another with 2gb of RAM, run BF3 on MAX settings on both, take a screen shot of a heavily detailed area, then compair.

In fact when I have the time I will run this test on my 560ti and my 680.

KoS has a thing about Vram if you haven't noticed!

Cleverly coded games will absord as much vram as they can to buffer against textures but that doesn't mean you need all the buffering in the world. Just take a look at all the benchmarks around for the current gen of 2gb cards. They all perform exceptionally so I wouldn't worry about it.

1gb vs 2gb is irrelevant, I didn't say 1gb is enough.

Yes but the driver has visual settings that can be dropped if you hit the max memory mark to compinsate. This is why you can get 60fps while being at the max memory mark and still be at max game settings. Also the application can only access 256mb without a driver. The driver allows the memory to be used.

Yeah windows has a thing about 256m. Probably a standard for something.

... Vram cap you will start using system RAM which is VERY slow ....

I still don't buy into this. Not with a modern computer. "Slower" yeah, benchie wize, not a massive hit tho.

I still reckon it's more to do with the game loading things into the memory to cut down on disk access. Not necessarily loading all the stuff you will immediately need to massively impact your fps, but to cut out future loading as you progress.

Cutting down on qualities despite settings I don't believe is plawsible. Possible yeah.

Don't know any of this for sure mind. Someone mentioned "cleverly coded games" ..... when they coming out ?

Touché! I was trying to suggest that this:

could be intentional by coders. Maybe I'm an optimist!

2GB for 1080p is plenty. Don't worry I say mate.
