Crysis 3 VRAM usage thread

post #1 of 99
Thread Starter 
So Im curious to see what other people are getting for VRAM usage in crysis 3 on ultra. Im sure that the results here will also help people upgrading cards in the near future decide what best suits them for their system/monitor configuration. Heres mine, and it would be nice if we could all follow a similar format:

Cards: 580 Lightning Xtreme SLI at stock clocks (3gb cards- 834mhz gpu clock)
Highest VRAM hit: just shy of 2.5gb
Resolution: Single 120hz monitor at 1920x1080



Definitely glad I opted for over 1.5gb cards for this. I never wanted to have to downgrade settings to get a game to run smoothly. Granted, some of this could just be driver optimizations/SLI profiles still needing some work, but within the first couple levels I could definitely see why it needed so much VRAM. This new engine is pretty bad ass. Also, I wonder if it is evidence of the drivers needing work that I have over 60% of my vram used, yet the memory controller never was logged over 20%? Or does it not scale with usage like I think it does?

Did you download the drivers that nvidia just released specifically for Crysis 3?

I have the ones they released like 5 days ago. What is the best version for crysis?

Wow so high VRAM needed in Crysis 3, but what about card with 2G VRAM? Need to see how much VRAM does it need?

Just tested my 670 sli setup in 8 vs 8 multiplayer, I maxed out the 2gb on my cards. Avg use was 1850-1950 but there were a bunch of times where it was hitting the wall. I use very high everything with 4x MSAA 16X AF 1080P and high quality settings in NV control panel. I'm also using the newest drivers just released recently.

Really kinda wishing I got the 4gb cards now, I never imagined I'd run out of VRAM before I ran out of power. This just gives another reason for AMD users to smile with their 3GB standard.

Edit: btw this is with only 78% GPU load.

The joke is on you. That means the game uses 2479/2 = ~ 1.25GB

So the number in GPUZ needs to be divided in half to get actual mem usage?

i think so, because we all know 2 x 2gb in sli is still 2gb. anyway, i get 1.6gb usage in singleplayer with everything maxed out cept for 2 msaa, at 1080p, with a single 680 2gb evga sc version. theres no way in hell this game uses 2.5gb vram, that's too nuts.

Wow I see, so if we use dual card then the real drawed VRAM will be splitted/divided by 2, right ZealotKi11er ?

Is that just something that GPU-z does? I get two values in Aida, free Vram and used Vram, free + used always equals 1535Mb (one cards total). It appears to be measuring one card only (and in SLi both cards have indentical copy of the Vram?

When I look at the GPU-z screenie posted above it shows 2.5Gb as around 85% full (3GB total), why would it combine the used VRAM from both cards and use a total from only one?
Not SLi any more
