worried about 2g vram

[elflegolas]

after i saw how amazing that cryengine3's quality
the first thing that come into my mind is will 2g vram enough for this?
becoz i just bought my 680 lighting 2weeks ago
did anyone running a 6802g suffered insufficient vram?
and if it does,it will result in stuttering?
all i need to run is 1080p

 

[seumasbeathan]

2gb should still be completely free I would think

 

[Josh Weston]

For a single 1080p monitor, you'll be just fine. Especially with the 680 Lightning

 

[elflegolas]

coz i suffered insufficient vram on my 460sli
that's why i replaced it....hope it wont
coz i saw the graphics of the cryengine3 is slightly better than frostbite2
and while bf3 already eat like 1.5gb of vram
that's why i worry about that

 

[elflegolas]

thought i dont really know what's the factor affecting vram consumption,is it the better graphics it has,it will eat more?

 

[seumasbeathan]

The more vram available the more will be used, if you have a 4gb card it will use more than a 1gb card although even on a 1080p monitor the chances are that the fps would be no different. (I don't think there is actually any cards you can get as 1gb or 4gb)

 

[elflegolas]

ic,ty mate ,so we cant tell how much the software's minimum requirement from a guy that have 4gb vram right?

What will happen is not a performance drop. The drivers will lower video quality through the drivers VERY slightly to stay within the 2gb mark. You will always be fine. The main things it drops is AF and some other texture settings in the driver itself to stay withing the 2gb mark. You should still be able to maintain the high FPS.

Its nothing to do with the drivers, the application has to control gpu memory.

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.

wait a minute...
i dont get it then
becoz my previous setup was 460sli 768mb
and when ever i hit the memory bottleneck
my fps slightly drop to 1 for 1-2 seconds then get back to 60
if this is not about vram,then what is it about?
also i have multiple friends told me they have similar problem when ever their card reaches its vram limit.
so why is that happening?and is this avoidable you mean?

Well the application might be using cpu side memory and then dynamically drawing, if it cannot allocate gpu side memory. So that means that vertex data/textures ect are travelling over the pci-e bus which compared to the gpus memory is slow. Therefore, resulting in a fps drop.

so which means if my card still reaches the limit of my vram
i will still result in fps drops?is that correct?
so there's nth difference isn't it?even the driver control it or what
i still get fps drop?

You just said you weant back up to 60FPS. What happens is whn youi hit your Vram cap you will start using system RAM which is VERY slow until the driver can lower visual settings to get you back at 60FPS. the quick drop in FPS is moving the rest to system ram and changing GPU driver settings (lowering settings) and once that happens you are back to 60FPS.

2gb ram is fine for 1080p.

Unless you are using a silly amount of texture mods in Skyrim(by silly,I mean as many HUGE texture packs as you can find) you will be fine.

Not really. BF3 on max 1080p settings I have seen hit 2gb of Vram.

 

[seumasbeathan]

How much vram did the card have that hit 2gb? I can play on a 1080p screen with a 1gb card and it only uses about 850mb

It has 2gb but the reason you are only using 850mb is because your drivers are dropping the settings so it ONLY uses 850mb. If you look at photos of games both using MAX and exact same setings at the same resolution, the card with the less VRAM will not look as good as the card with more vram.

Sounds like rubbish to me
