1.2GB enough for BF3? - Page 3

I believe the third map is the hardest to run, but it's also the hardest to get to.

Here's a fraps readout at 880/2100 on my 470s in SLI (1.28GB).

First part:

Frames, Time (ms), Min, Max, Avg
34974, 426444, 58, 130, 82.013

Second part:

Frames, Time (ms), Min, Max, Avg
49314, 472075, 62, 151, 104.462

Third part:

Frames, Time (ms), Min, Max, Avg
24740, 274359, 52, 123, 90.174


Fourth Part:

Frames, Time (ms), Min, Max, Avg
15811, 210336, 57, 115, 75.170

I hope this helps


These aren't the big maps, I have no idea what's going to happen after beta ends but hopefully the code gets optimized and the additional graphical features are added.


The extra vram of the AMD cards wouldn't be a bad thing, the only concern with AMD cards is the FPS aren't very high in this game, AMD cards are probably going to produce noticeable MS because of that, and tessellation hasn't been added yet. AMD has the tessellation performance of 560ti's, which are several steps below even 470's which are on the lowest end of the tess unit totem pole 560ti > 470 > 480/570 > 580.

I will admit with all the vram fear mongering from AMD users I bought a 2x4gb kit of ram, I'd rather have the swap taking place in my system ram than in my pagefile.

i think it uses all the VRAM it has avalible to it... or atleast most of it...

because on my 450 at work it uses 980mb

while on my PC at home with the 2x480s it uses 1380mb

both at 1080p...

both run smooth...

and it uses 1400mb for 3x1080p surround

Instead of rebuttle, I'll leave food for thought....

I find it ironic how people suggest on a single monitor 1.25GB isn't enough VRAM for intensive games because it's more VRAM demanding.

However 2GB is enough VRAM across three monitors?

SO I'm going to assume that 2GB VRAM is no longer acceptable across three monitors with games that use up more VRAM upcoming and everyone needs to change to 3GB VRAM cards that are using multiple monitors?

IMO the 570 1.25GB card is enough VRAM for BF3, Crysis, Crysis 2, Metro 2033 to be able to handle gaming and provide good FPS on a single 1920x1080p monitor.

A video card with high memory bandwidth can draw faster and draw higher quality images. You have to consider and factor in the speed of the GPU as well into the equation. Having more VRAM with lesser GPU has the same effect only vice versa.

You only need higher VRAM amounts when you use 1440p or 1600p, or multiple monitors.

Just my

Try single 570 for now. Then SLI after the release. Those are my plans.

I've been hearing that the "ultra" mode isn't properly turned on in the beta anyway so the texture size may increase. Best bet would be to wait for the actual release and choose then.

Myself i'm looking to get a 3gb GTX 580 at the end of the month.May not be needed now but games next year or the year after may need 2gb to 3gb to get the most out of them and I don't want to have to sell this card and get another just for an extra little bit of ram.
espescially since there's not a lot of difference in prices.

Maybe it'll be fine for a few years but computer trends tend to go one way in terms of resources and i'll be err'ing on the side of caution.

Seems that CPU's are moving toward handling some graphic loads as we look down the road into the future to lift some of the burden off GPU's.

We'll have to wait and see if it helps the deticated GPU's or not if CPU's can serve in aide with intergrated graphic functions.

Since most users don't multitask while gaming I can't see this being an issue that will conflict with the CPU function in the first place.

IF Nvidia and AMD keep heading down this road as chips progress it may be a game changer on what's actually needed from deticated GPU's.

Beta's usually have very poor memory management, usually caused by a number of things but 1 of them is textures being rendered and put into memory even though they aren't actually visible. When the final optimised release is out it'll probably use quite a bit less than it does now. I shouldn't worry mate.
