Low CPU/GPU usage BF3 paired with low fps?

Last response: in CPUs

January 22, 2013 5:22:54 PM

So, recently I installed my brand new gigabyte 7950 into my custom built PC. I started up battlefield 3, (it's a great game and a good way to stress test my cpu/gpu) and I got average/low fps. What's odd is that even after I formatted my hard drive, Re installed the latest drivers, and overclocked, my CPU usage never goes above 65% and my GPU usage never goes above 70%. I've tried overclocking both to no avail. I know for a fact that it's not a cpu bottleneck, because it's usage is always low.
Any ideas?

PS:( Please Intel fanboys, restrain yourselves. This CPU is great, it's just not using itself very well.)

Specs here:
PSU: Rosewill GREEN 630w
GPU: Gigabyte 7950 windforce edition
CPU: FX-6200
HDD: 1TB WD 7200

My fps idles between 30-60 on ultra, and my temps are always good, below 60c

thats weird, u should get 50 ish in ultra. have u tried defragmenting ur hard-drive. game folder for bf3. scandisking it, and running cccleaner to clean ur registry?

also running the latest drivers from amd?

no i asked if ur overclocking it, cuz somethimes can cause performance issues.

The CPU or GPU? I've tried both separately, and neither caused any problems or made it run faster :/

Not clocking any more, the old clock was at 1100/1500 using afterburner. Still getting the same problem even after restoring defaults.

Oh, and now the gpu usage goes up to 75%, but never 99 which I hear is the max amount.

That's what I do, I lower mesh quality and the framerate gets a huge boost. Anyway, 30 fps is still very playable and it does average above that. A new cpu heatsink is going to be here soon, so I'll try overclocking some more. :/

Your processor can't keep up it's bottlenecking.

Ultra bf3 is too much.



Turn down or completely off cpu intensive eye candy, Post processing, Shadows & Physics etc.

already been discussed, his cpu can keep up if overclocked beyond 4.5

How about your memory use? GPU ram are reg ram? Do you have a lot of background programs running?

The 1st thing I would do is turn off AA. Then run a few MP maps..check FPS..then slowly turn it up and keep checking.

Then play with the other settings till you find a good mix.

You can also try other drivers ...roll em back to see if others are better. I am getting FPS dips more so now than before and I run 560s in sli. It may be something about the new maps. More things going on in less space.

If that is for the CPU as a whole - do you have usage figures per core?

So, I left vsync on, that turned out to be rather problematic. I turned it off and now my gpu is being fully utilized for most of the time. This still brings to question the lack of CPU usage, I guess it's just a good cpu, as it still gets around 65% used when my card is working 99% loaded.

65% means that 4 cores are maxed and 2 are idle. BF3 doesn't utilize more than 4 threads, your CPU is bottlenecking.

Yeah, as it turns out vsync was limiting my GPU usage, there's no bottlenecking.

haha this made me laugh. its not intel fan boyism to acknowledge that intel make superior processors. your processor is good you are correct but it is not as good as you like to think.

false, bf3 will use more then 4 cores if you give it more then 4 cores. i routinely use 5 cores at 70% minimum.

that 70% for GPU usage means gpu is useing 70% from clocks not the power of gpu. Can be 100% gpu clock and 40% memory clock and that means 70% from maximul clocks. w/e a gpu is more complicated than clocks , u shoulden't watch usage, ur gpu is working as hard is posible. same for CPU , u can see 20% CPu usage, but it runs on maximum transfer rate.

Sorry, forgot to mention, I'm metering both the core usage and the mem usage. But I think the reason why my framerate is low is because my cpu is bottlenecking my gpu on full servers (bf3 is very cpu intensive in multiplayer). I think the best choice is to upgrade to an 8350, thanks for y'alls help. :)

u got a 6 cores cpu, there is no way for bottleneck!

this is just plain untrue. it CAN be the bottleneck. people are just ignorant to the amount of CPU the frostbite 2 engine can and will take up. it will basically take up to 6 cores(note i use the word cores not thread which applies to both hyperthreading and AMD modules) and will continue to gain fps on intel i7's at clock rates up to 4.5 ghz.

people please get the ignorant thought of bf3 is not cpu bound out of your stubborn minds.
