how much Vram?

post #1 of 15
Thread Starter 
I am trying to figure out how much my GPU is using to run BF3. I started with settings on auto which seemed to be laggy and stuttery. So For Fun i ran all settings on low, Yes it seemed to run a little smoother, It wasn't butter smooth which it should be. I am talking about the single player part of the game. This has nothing to do with servers on anything online. So what can I use to monitor how hard my GPU is working as I turn up the video settings one by one till I hit my max Vram amount? If I stay just below my max Vram it should run fine right?
Kinda like when you load GTA4 it has that screen as you adjust your video options it shows you how much Vram will be used when you adjust every setting?
Thats what i want. I want to be able to run this game on as high as settings as possible, Who doesn't right?
I just dropped over 1500 hundred bucks to be able to run this game on high/ultra settings. Anyone have a suggestion for me.?
Thanx

Game is a vram hog. Seems for 1080 single display the sweet spot is 1.3GB or more.

you can use this program to monitor vram for Nvidia and Ati.

Yup this game uses a lot of vram and your card may be running out when putting MSAA on.

Just use MSI Afterburner to see how much VRam is being used in game. Install afterburner, then go monitoring in settings tab and click on screen display for memory usage.

I just got done in ULTRA settings playing campaign. Had GPU-Z monitoring. I own one GTX 580 slightly over clocked 24/7 by 13% at stock voltage.

Highest temp 73C average was 70C
Highest VRAM used 1.474 GB VRAM.

I don't have a way to record FRAPS but the free version let's me see FPS in upper left hand corner. I was anywhere from 50-70 FPS. No stutter or lag even in intensive battle scenes of explosions while firing on the move with smoke/fire all around, and people coming at me. thumb.gif

Because you have 1.5GB VRAM right?

Everybody always says oh the game uses 1.4GB, 1.7GB, 2GB etc. It's all down to how much your graphics card has. The game only needs 1.3GB at max settings but it will keep on using more if it's available, it doesn't need it though. What I'm saying is e.g. don't go and buy a GTX580 with 3GB because you saw some guy with a GTX580 3GB saying BF3 uses over 2GB of VRAM. Or somebody with a 6950 2GB saying the game uses 1.7GB VRAM so you really need the extra, it's bull****. For other games you may need a lot more than 1GB VRAM, for BF3 you don't. The fact that somebody is maxing the game with a 2GB card using most of their VRAM and amazonian with a 1.5GB card is using most of his VRAM, then some other guy using a 580 3GB is using most of their VRAM (but none of their cards reach or exceed their VRAM limit in BF3) all at max settings proves this.

WOW, you took that personal. eek.gif Is this a touchy subject for you? tongue.gif

I only stated nothing more than I monitored. Never suggested anything about all that you just posted.

The OP said "how much VRAM?" I just stated 'how much VRAM'. Simply from my specs GPU-Z recorded. Eventually he will come to his own conclusion as more people post what he might want.


Now that you've opened this can of worms, let me give you my actual opinion rather than you cram something you think I insinuated down my throat.

I feel that a GPU can exceed about 500MB more VRAM than it has without causing it to bottle neck and before you might experience slow down. It can share from system RAM as it spread memory across the monitor to some point.

Example would be Crysis 2 DX11 Ultra settings. I max my GPU VRAM past 1.5GB yet I don't experience much less FPS at all over someone with 2GB. Another point I'll make is there is no difference in gaming on a single 1920x1200 resolution monitor between 1.5GB and 3.0GB of VRAM. In fact here is a perfect example that between the two on single monitor there is only but 1 FPS difference.

It's not until you hit multiple monitors where VRAM is king. Yes, eventually spread across three screens you will see better performance from having more VRAM.

lol, only the top line was in reply to you, the rest was warning the OP that just because people with loads of VRAM report that the game uses most of their VRAM, it doesn't mean he needs that much VRAM too or his performance will suffer. icon14.gif

A guy just posted before you in another thread you were in my exact example but in reality, he said he had a 3GB 580 and he's using over 2GB at 1600 resolution, this is the kind of stuff that can confuse people as they then think "oh well I must need more than 2GB VRAM to do that too or my game will run crap" when in the case of BF3 at least, it won't.

Here's the post:

He's only using over 2GB VRAM because he has over 2GB VRAM, the game doesn't need it but it seems most people seeing usage this high on their cards actually think it's really needed and if they had less it would be a problem.

It's already widely known that BF3 has a memory leak bug. No matter what your GPU's vram capacity is, the game will almost use it all up. It's no coincidence that every person has there VRAM usage almost peaking at their GPU's capacity. It's a bug....

Now whether this memory leak is a convenience for the likes of Nvidia is another matter entirely. But i won't go down that round....but think about it for a moment.

Is it a leak though? I thought this leak was with system memory not VRAM, and I thought the way it uses VRAM is intentional so it just makes the best use of what you have, that streaming technology or whatever they called it.
