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

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.

Just get the maximum you can , the graphics will only get better from here anyway. Never mind if the card isn't being utilized to the full , it will be with further updates. 6990's have 4GB of memory , but for the price i'm looking at the 6970's.

this isn't exactly accurate. the 6990 has 2 gpus each with a 2gb frame buffer. those don't combine to equal 4gbs those are two separate 2gb buffers.

further until sli/crossfire works in cod there is no point to the 590 or 6990 or any multi gpu setup for that matter.

The 6990 is a great card but with pathetic cooling, search Youtube, you won't be able to hear anything with the fan runnning. Wait for Gigabyte etc to release tri-fan 6990, Or better look at GTX 590 .

ok, 2 GPUS won't improve VRAM but doubling GPUS surely will

Hi all,

New to these forums. DL'ing the game now (Steam).

Just a (probably silly) suggestion, but has anyone gone into task manager and set the CoD process priority to high and the affinity to force all CPU cores used?

I doubt this will change anything, though I have had some success in the passed on previous games.

Andrew,

1.2gb free flight over London - see attached screenshot - PS loads showing zero as I had to go back to desktop for screenshot - in game 99% GPU load on 1st GPU - 2nd idle (SLI not working - as we already know)

GTX 570 1280MB VRAM used up at 1680*1050 ultra high setting on London.
Any guys have 2G VRAM tested it?

2xAA and 2xAF still only using 980-1gb ram. the game is likely reserving a small amount of the GPU memory space.

performance wasn't any better or worse with these settings enabled/disabled. also, performance from medium to ultra didnt change for me either.

again, this points to a cpu bottlneck not a gpu bottleneck.

my system is:
c2d e7200 @ 3.2ghz
4gb ddr2 @ 1066mhz
gtx460se @ 850mhz core/1700mhz shader 1990mhz ram clock

gives me about 10fps average low over london with ultra settings except seizure filter, grass, shadows, and roads unchecked with irror disabled.

again ram utilization hovers between 980-1010.
