Battlefield 3 total system resource benchmarks.

You're completely looking at windows memory usage graph wrong as well, the graph itself only displays 'physical usage'. Underneath the graph it also lists how much additional ram is being used to cache on top of that, and how much ram is still free.

Most of the additional system ram will be used up fpr caching everything including Vram data and windows leaving next to nothing free. You need far more than 4 Gb to allow this to happen so you don't get lag spikes.
 
AlxAndy - You are in no way certified or knowledgeable enough to comment on the numbers you are reading. Do you even understand the core system functions behind them?

90 seconds is also the most ridiculous time period I have ever seen from which to gather meaningful FPS averages over. The Heaven benchmarl run is what, 250 seconds? My average FPS can deviate +/-20 FPS over the course of those 5 minutes and you are pulling supposedly MEANINGFUL stats from a fraction of the time with difference of +/- ~8FPS.

If you are going to do it, at least do it properly.

BTW Ive already posted system ram usage graphs throughout the memory section of this forum showing all of 24 Gb being used up for caching on top of 4.5 Gb physical ram being used while gaming with less than 1-2 Gb system ram left free, and this was with other games, not BF3.

This is the proven basis on why 8 Gb is now recommended as a minimum, as well as its low price. Everyone on this forum that has upgraded from 4 Gb to 8 Gb has reported far less lag and much improved performance in games.

Only having 4-6 Gb system ram is the primary cause of lag in any current system, because you won't have any room for caching. Vram is always the final cause of lag after CPU, GPU and System ram. Eliminate the primary bottlenecks first before obsessing over Vram and you will find that in the majority of cases, Vram was not the cause of your lag, some other bottleneck in your system was.

There needs to be a new thread made and stickied advising newcomers to this forum not to read a single thread or post made by ALXandy.

I pointed out that it was not a benchmark. Quite clearly as system specs differ wildly. What it was, however, was a demonstration of vram usage and a display of how BF3 uses lots of it.

How about you do something meaningful, and try the same tests and post the results?

Same goes for any one who wants to argue the toss. Put your money where your mouth is.

I had a modern 2600K system with 4GB of RAM and BF3 caused Windows "Low Memory" errors.

Another 4GB bought instantly.

Yup, had a similar issue here, needed more RAM to sort out the issue.

Going from 4 to 8GB RAM solved it entirely.

Totally unrelated to VRAM though as the game was using well below 2GB of the dedicated memory (Radeon 6950 unlocked 2GB).

OK fair enough. However, this thread was to show how when you run out of vram the game in question will cache from your page file. And, how more vram is used when it is disabled as caching is eliminated.
 
played caspian bf3 on high preset on my lowly 4870 512mb
max usage i saw on afterburner was 501mb
played about 5minutes and I had to stop since the slideshow is making feel sick and dizzy :D
I didnt experienced the crash but i think the short playtime may be a factor

my specs are:
stock 2500k
8gb ram
4870 512mb
 
I don't need to run these tests again because I've already done them several times with Civilazation 5 and Dungeons and Dragons online both of which exceed 4 gb physical ram use and completly fill up every bit of my system ram with caching leaving next to none of it free.

The results were posted in the memory section, and civilization 5 threads, and that game will actually gobble up every last system resource you have, all your ram, all your vram, every physical core of an Intel hex core CPU.

I also correctly concluded my results, and posted them in a valid format that everyone understood regarding system ram and caching limitations.

You are clearly not qualified to be posting this kind of information, your OP and subsequent posts in this thread clearly show that you have absolutely no idea what you are talking about, and that you lack the knowledge to understand the data you are posting.

Basically you have no clue and are chatting BS again as you always do.

I am not intimate with the inner workings of Windows file system and would not dare comment on numbers pulled from resource monitor without knowing the technology like the back of my hand.

I am not a GPU engineer or a file system engineer and therefore can draw no meaningful conclusions, as you cannot.

Many apps will not run properly without a Page File irrespective of whether they NEED it or not. Simply concluding BF3 needs the VRAM because without the page file in supposed VRAM limited situations BF3 crashes is ridiculous.

Did you disable your page file? Memory usage is about right for a 512mb card. Windows is running underneath. Basically you are using all of your vram and then BF3 is caching the rest into your paging file.
 
Just did 15 minutes of Caspian Border 64/64 server and my system ram with the monitoring software running cam to about 4.9GB system ram used and I doubt it is displaying right because of crossfire but the latest version of GPU-Z (0.6.0) says the max memory usage was 2663MB.

This is all with page filing enabled

Stop posting as an authority that you are not.

You are misleading people with trash data to backup your claims.
 
The game uses more VRAM since the patch, pre-patch people were saying it wasnt using enough.. If your settings, pre-patch, used enough VRAM and your page file is disabled the result, post-patch, is somewhat obvious. Either drop your settings or enable the page file. I have 512mb of VRAM, 8gb of RAM and no page file, but my settings arent high enough to cause me any issues (low everything except mesh, I am not there for the scenery).
 
1GB 5850, 4GB DDR2 ram. 1920x1080p res

OK disabled pagefile.

GPUZ 0.6.0

Tried getting into caspian border 64 player server and while the game was loading, vram (dedicated) filled upto 650MB and dynamic memory (I believe it is hard disk related) filled upto 107MB, before the game crashed and I received the windows low memory message error.

Does it mean BF3 uses more than 1GB vram easily and pagefiling from HDD is a must with only 1024MB vram? :(

Yea pagefile was disabled when i ran it

either way gonna revert everything back to previous settings later after i recover lol

plus it wont matter much for me soon as im planning on upgrading
