VRAM Usage - 6970 (2 GB) vs. GTX 580 (1,5 GB) vs. GTX 580 (3 GB)

Hey guys,

What is the max. amount of VRAM CloD uses atm if the GFX card has enough?
And what will give the most performance?
I will chose my GFX card according to this.

Does it use ...
> 2 GB or close to --> GTX 580 (3 GB)
> 1,5 GB or close to --> Ati 6970 (2 GB)
< 1,5 GB --> GTX 580 (1,5 GB)

download rivatuner and set up real time monitoring and find out for yourself?

at medium settings spawning into the london sight seeing and flying around a bit has me at about 950-970mb out of a max of 1024mb.

My advice is to wait for the next patch before purchasing. I don't think (?) anyone has seen a max yet (i.e. GPU memory that is not utilised) - I certainly don't with the 1.5 Gb on my GTX480.

doesn't make any sense for me 'cause I want to play the game on high to full settings and I am sure that my current card (GTX 285 1GB) first of all has not enough VRAM and secondly doesn't have enough computing power.

It would be great if the people that have a 2 GB card could test how much of VRAM is used on maxed out settings and 1920x1080.

But thanks madrebel for your numbers.

hold on lemme change some stuff to high and see if it maxes out.

Hm, settings on medium, doesn't tell that much.

switched to ultra settings with shadows, grass, and roads unchecked. at 1000 feet or so it was using 970mb. once i got real low over buckingham pallace it spiked to just over 1gb.

enabling AA or AAF would likely spike/peg the memory at 1024mbs. lets try that next.

with 2x AA i am 980-1gb ram. however what is more interesting here is my GPU is only averaging 45-55% utilization. this points to a fairly significant CPU bottlneck which likely should be somewhat cleared up when they fix multi core support. when one core is doing nothing but rendering frames and the other core is doing all the simulation stuff GPU utilizaton should increase.

gunna try AF settings now, will take a few minutes as i have to do that via nvidia control panel.

What is your card? My 480 is maxed.
