BF4 Limited Resource Usage

Zippyo3 · Jan 23, 2014

Ok So i've been monitoring my hardware usage for battlefield 4 today and i'm noticing something surprising. It appears battlefield 4 is only using a portion of my hardwares power and i was wondering if anyone could explain why.

So my system specs

Intel Core 2 Quad Q8400s 2.66Ghz
6GB Ram
Radeon R9 270x 2GB

I'm Running battlefield 4 in Ultra Settings and getting a consistent 48 - 60 FPS

Using MSI Afterburner my card's reading at about 48% usage.

My Cpu is Reading about 60-80% Usage.

My First thought was a bottleneck, but if that was so wouldn't 100% of the cpu be being utilized?

Hoping i can get some clarification on this.

Many Thanks

Nothing uses 100% of your resources. It loads when it needs to load something.

were you windowed reading that? your card should be @ 100%, i wouldnt be surprised if your cpu was close to 100 in bigger games

Thanks for your reply. Nope was reading it from secondary monitor while in-game.

something is wrong if its only using 48% on ultra

Alec Mowat · Jan 23, 2014

48% usage in what? Fan speed? Memory? Core clock?

Alec Mowat :

i'd say he meant 48% gpu usage but that cant be possible, so it has to be fan speed %

I just ran the game with a 670, it only runs about 40-68% according to MSI. That's normal

Programs don't run your card 100% all the time. It only loads if it's doing something. Once the map is loaded and the textures are in the ram, it doesn't need to work at 100%.

Zippyo3 · Jan 23, 2014

Yeah I'm talking about 48% usage, which I thought was weird. Playing other games such as arma 2 uses a lot more gpu. Well once the cards loaded in the textures etc like you said, why would it leave all that processing power just idle?

Alec Mowat :

depending on what settings you play it it will load it higher, like turning AA up to max should raise it quite a bit, plus if you play with the resolution settings over 100 it will surely keep your card at 100%

my cards run at 85+ mostly in the 90s while playing bf4

the only other time it wont go to full load if your cpu cant keep up/ is running full load

Did you disable vsync?

06yfz450ridr · Jan 23, 2014

Alec Mowat :

yes sir vsync is horrible since it causes input lag, on vysnc it will keep my cards basically at 100

I am also playing on 1440p which has much more pixels, even on my 1080 it was still a fairly high load

Alec Mowat · Jan 23, 2014

I leave vync on or I get horrible tearing (mind you I'm on a TV).
Time to crank the graphics to Ultra and see what it does.

Alec Mowat · Jan 23, 2014

Yup that did it.

OP, disable vsync in the settings and see what it does.

Zippyo3 · Jan 23, 2014

Vsync is/was disabled at the time of testing.

Going with CPU bottle neck. Asked a friend with a similar CPU and he gets the same result. The Core2's just can't process fast enough to keep up.
