video ram for 3d gaming

[dodo]

I want to know if i have more video ram will help in 3d gaming on a single monitor.

2gb is enough ? (gtx 660 ti)

That should be enough for a single monitor, yes.

Ram is mainly for the amount of monitors.

Ram is mainly for the amount of monitors.

Or more specifically, the resolution.

Depends on the game that you are running some games will consume more memory than others. For 3D.

Ideally for 3D you would add a second card in there to help the computer run better because with a single slower card you will start hitting the boundaries of what one GPU can push.

To answer your question however, yes it will work with one, but if your only doing to use a single card then get the fastest single card that you can it will make it more enjoyable.

Well black ops 2 use 1,7Gb ram in 1080p so 3Gb will be needed.

Matter of time but 2Gb will do.

Or if you play games only like minecraft stick to 1Gb

Yeah the amount of RAM needed would be exactly double the amount used for 2D as i understand it.

60-120Hz. 3D uses 2 overlapping images in order to create that feeling of depth so it should be exactly 2x?

Also adding a second card will not help with the memory buffer.

2 x 2Gb cards will still only have 2Gb that is utilised. They dont add together for a total of 4Gb.

I currently have a 680 with 2Gb and dont think it would be great for 3D. May be fine with some games but not all. Plus it will only get worse as more intensive games are released.

As dav1257 said x2 2gb cards dose NOT MEAN YOU GET 4GB of ram so adding another card like the one you have will not help if you are running into that when running 3D games.

think of a sequence where each frame is named: 1, 2, 3, 4, 5, 6, 7, and 8.

Card 1 will render frames 1, 3, 5, and 7.

Card 2 will render frames 2, 4, 6, and 8.

Now imagine 2 workers(your gpu's) and they each are well rested and have lots of energy(the ram of the card) they are told to do a job that 1 man can do, they will obviously finish the job faster, but they can only use there energy to do there part of the job, they can't share energy if one of them gets tired.

this turned away from will that run 3D games but thought i would clarify for anyone that thought if you get x2 2gb cards you get 4gb of ram.

In reference to dav1257's post: I'm pretty sure that 3D doesn't require 2x vram or in fact that much more vram at all. The way I see it (and please, correct me if I'm wrong) is that the two frames are not rendered simultaneously as they cannot be simultaneously rendered on the monitor. This is why a 120hz monitor is required; the actual game runs effectively at 60hz, because there are two discrete frames required (one per eye). This results in 60x2 = 120 which fills the whole 120hz capacity. What the gpu does is effectively render the same scene at a slightly adjusted angle. This means that the gpu is still rendering the same scene and therefore does not require additional vram. The way the 3D works is in the glasses, with the glasses preventing one eye from seeing one of the frames and only seeing the other. This is why they are referred to as shutter glasses (first they shut one eye so the other eye sees its frame and then the shutters swap) and are so expensive and require power.

2Gb of Ram will do the job great. I currently have a 560 Ti with 1GB of GDDR5 Ram so i bet yours will do twice as better then mine :)

For a single monitor 2GB will be just fine, even for 3d.

2GB to 4GB should do the job nicely with high "texture" games
