Battlefield 4 using 3.8K of CPU memory and 8GB of RAM?

TheTenaciousOtaku · Sep 13, 2015

BF4 on my system uses 1240 / 1280MB on both my SLI GTX 570 GPU's and 90% of my 8GB RAM. Task manager says that BF4 is using 3.8 K (whatever this means) in the memory column.

8GB of ram seems quite excessive right? I had minimal applications running when I wrote down those stats. Anyone have any ideas as why BF4 eats so much resources??

When I played BF4, I had TeamSpeak, Chrome and BF4 open. It wasn't uncommon for my RAM usage to sit at 5+GB. As for VRAM again, it just does on higher settings. My 770 GTX used 1.7GB easily in BF4. There were tests done a year or two ago where BF4 can use just over 2GB of VRAM. It's a system intense game.

What OS are you using?

No problem. I can unselect it. Once you post enough, you'll be able to as well.

What other applications are you running? What browser? As for the 3.7k RAM usage, are you sure it's not 3.7k MB (3700 MB), thus 3.7GB?

I'm not running enough applications to warrant the full 8GB to be used... It doesn't add up..

Task Manager
Image Name / Memory (Private Working Set)
bf4.exe / 3,800,000
Chrome.exe *32 / 130,000 K
Chrome.exe *32 / 100,000 K
Chrome.exe *32 / 90,000 K
Chrome.exe *32 / 70,000 K
Chrome.exe *32 / 70,000 K
Chrome.exe *32 / 65,000 K
Chrome.exe *32 / 65,000 K
Chrome.exe *32 / 60,000 K
Chrome.exe *32 / 50,000 K
Chrome.exe *32 / 40,000 K
Chrome.exe *32 / 10,000 K

Total = Roughly 4,555,000 K (with all over applications included)

@TheTenaciousOtaku, watch your language.

While Chrome is using quite a bit of RAM, the ~4GB sounds about right when running BF4. So I wouldn't say it's BF4. I'd say it other applications that are using it. Try a different browser and keep Chrome closed.

barto :

Sometimes after about 20 minutes of playing BF4, the frame-rate will drop from an average of 70 to 25. Through trial and error, I figured out that closing the Google Chrome browser instantly boosts my frames back up to 70. The factor which doesn't add up though is that task manager states that the Chrome browser only accounts for roughly 750,000 K.

Even with BF4 and Chrome open, there should technically be 3.5GB of RAM left to spare. The other background applications etc definitely don't account for 3.5GB but Task Manager doesn't show any other big RAM eaters which is so unhelpful!

Hmm. This is definitely an odd one. Do me a favor, lower the settings on BF4 so it uses less VRAM. Then check system performances (CPU Usage, GPU usage, RAM, VRAM) with Chrome open and then closed. Then go back to the settings you had applied normally and do the same thing. You should have 4 sets of results.

Chrome open

CPU: 4.1K
GPU: 90% by the time the game minimizes, so I asume it's at 100% when in-game
VRAM: 1056/1280
RAM: 94 - 100% (8GB)

Chrome closed

CPU: 4.1K
GPU: 90
VRAM: 969
RAM: 88

And with the settings lowered? Just curious what happens. You only posted 2 of the 4 sets. For example: Ultra + Chrome open. Ultra w/o Chrome open. Medium + Chrome Open. Medium w/o Chrome opened.
