BF4 Drop FPS from 60 to 25

Bziot · Jun 8, 2016

Hi there im having a issue while playing BF4, im having FPS drop from 60 to 25 and go back to 60. Those are the "solution" i tried:

1° Re-install C++ 86 and 64, re- installa DX (All from Bf4 folders), re-installed PB from official Web.
2° Disabled Origin in Game, executed 86 and 64 bits.
3° Repair the client, unistalled and re installed BF4.
4° Even with lowest graphics get the same FPS as High settings and same issue.
4°B Disabled VSync.
5° I did googled and found a cfg that might be the "fix" but didnt work.
6° Processes are all clean, did clean format still having the issue.
7° GPU drivers are updated.

And keep having this issue.

My PC specs:
Win7 64 professional
A8 6600K 4.2ghz (with boost)
8gb (2x4) 1600 mhz
R7 260X 2gb.
HDD 1 TB
EVGA 500w certified

NOTE: Temp from CPU not reach the 70° in real time playing, GPU no reach the 50°.
Didnt do any change to the hardware or OC.

Thanks for the help.

Enable the gpu/cpu graph in the game options, that might help you in the right direction.

How is the command for CPU graph?

Tbonius · Jun 8, 2016

Hit the console key(tilde), then type "PerfOverlay.DrawGraph 1". Change the 1 to 0 to turn it off.

This spike happend every 10-20 secs.

Is this when you are having the fps drops?

Bziot · Jun 8, 2016

Tbonius :

Yes, apparently when the CPU spike is UP, the FPS go down.

Tbonius · Jun 8, 2016

It's interesting that both the gpu and cpu are spiking, stand by, I'm checking something in my settings.

Tbonius · Jun 8, 2016

First thing is to disable "Origin In Game". Do you have anything else running in the background when you are playing?

Bziot · Jun 8, 2016

Tbonius :

Discord, Google Chrome, Origin, puush. Nothing Else. Origin in game is disable.

I was checking my nvidia settings, then realized that you have an amd card. Is there anywhere in the amd settings where you can change the maximum pre-rendered frames

I googled it and I couldn't find anything on amd cards and maximum pre-rendered frames, which is a setting in the nvidia control panel that really smooths things out. I've dealt with a lot of things in bf4, but with an intel/nvidia system it's hard to cross them over to your problem. 2 gig of vram is about the bare minimum, did you try it with all of your video settings on low?

Bziot · Jun 8, 2016

Tbonius :

Yes, even high or low is the same.

I looked at your screenshot again and it seems your cpu is carrying way too much of the load. The cpu spiking may be because it is taking over for the gpu(it has a corresponding spike). For some reason you gpu is under-performing.

The weird thing a month ago i was able to play without this issue, im gonna do a clean install of SO will take me less time than looking for a fix. After trying i will let u know if it fix it

Tbonius · Jun 8, 2016

I was looking around on the internet and people have all sorts of fixes from changing your page file size to unparking your cpu cores. Now if you say that it was fine a month ago and now it's acting up, a clean install is probably a good idea. Had you changed any drivers or install programs around the same time the problem started? In any case, I'm sorry I wasn't more help and good luck.

Bziot · Jun 8, 2016

Tbonius :

I always unpark the core after i re install SO, and yes i did try about the page file size, im downloading old gpu drivers from 4/4/2016. And i will try with those, thanks anyway for helping

Bziot :

If you get 55% CPU usage while playing the game than it only uses half your cores so that's probably the problem,something changed in your config.
You can try Thread.MaxProcessorCount 4 in the console commands.

Bziot · Jun 9, 2016

TerryLaze :

This command Thread.MaxProcessorCount was for default 5, anyway setted up to 4.

I just play for 10 min straight and the FPS always stay at 50-60 with high graphs. May be was a process that appear every 20 secs and use 100% of CPU. After clean SO install, installed drivers, Origin, Discord, Chrome, Punkbuster, re-download BF4, and works without problems.
