Lagg in Bf3 With Good PC?

samborambo56 · Dec 28, 2013

So I have:
AMD Radeon 7870 2GB DDR5
AMD Fx Quad Core 4100
8GB RAM
1.5TB of HDD

Whenever I look at large battles on Bf3 my framerate drops significantly :/

Any ideas as to why?

Nefos · Dec 28, 2013

it will be your CPU
your CPU is not powerfull enough and BF3 multi requires pretty powerful CPU as well

Scremin34Egl · Dec 28, 2013

Is it the singleplayer or multiplayer?

Scremin34Egl :

Multiplayer 64 man servers

CPU. You'll need a pretty beefy chip for 64p. I have an Atlon II X4, I usually get 30-40 fps on MP, but in 64p on small maps it sometimes drops to 20s.

So say I get an Fx 6300 will than improve performance much do you reckon?

Scremin34Egl · Dec 28, 2013

samborambo56 :

Yes, you should see a significant gain in performance with that cpu

samborambo56 :

Go with the 8320 it's only $10 more and you'll see a vast improvement.

Nefos · Dec 28, 2013

RazerZ :

actually you are half right
yes, for 10$ definitely go with 8320
but about ingame performance there is only a low difference, as games are not threaded enough, but that might change in the future
BUT can your motherboard handle a 125W CPU? that is the main question

I meant the improvement from upgrading the 4100.

It seems that your cpu is the problem, it cant cope with the heavy load.

ohh, yea, i see, thats right
OP what motherboard do you have? so we could advise you the maximum upgrade you can/should get

Shouldn't most motherboards with an AM3+ socket support an 8320? Assuming this isn't a prebuilt.

Nefos · Dec 28, 2013

the problem here is that 8320 has a 125W TDP that some lower end motherboards does not support, some of them support CPUs up to 100W, that is the problem here

RazerZ · Dec 28, 2013

Nefos :

TDP shouldnt be a problem its a guideline for the CPU cooler.

Nefos · Dec 28, 2013

actually loads of 760G chipset only support CPUs until 95W, 970 usually support up to 125W
you are right, TDP is for temperature, but it does indicates how much power does the CPU use, higher the TDP=more power it uses.
