Hello there!
As I was having problems regarding stuttering with Battlefield 4 since I started playing it, I decided to run DPC Latency Checker and see if it helps me find the culprits. What I found was pretty weird. The latency was at 1000us with occasional red spikes that are more present during the gameplay. I've tried disabling network adapter, sound and USB ports and nothing helped...
Here is a screenshot to visualize the problem:

I heard that it is normal for a system to have below 500us if I'm not mistaken and this is way above that. Maybe it is my HDD as it is pretty old (around 4.5 years) and it's SATA. I've tried disabling virtual memory and it seems that it helps a bit fix the stuttering. Also this video shows my problem exactly: https://www.youtube.com/watch?v=c49p55OI2vY

My system:
Motherboard: Gigabyte 970A-D3 (Latest FD bios. Was thinking of downgrading, maybe it has to do something with it, what do you think?)
CPU: AMD FX-8320 @ 3.5ghz
GPU: ASUS HD7790 DirectCU II
RAM: Kingston HyperX DDR3 2x4GB @ 1600mhz (X.M.P is on)
HDD: WD 320GB SATA (To be precise: WDC WD3200AAKS-00L9A0 ATA Device; that's what it says in Device Manager)
PSU: LC Power LC600H-12 600W
Windows 8.1 Pro x64

Any help would be greatly appreciated!
 
Hi,
playing online game on wireless will get you poor performance.
First off, even the fastest wireless speed is no match to a wired one.
in second, wireless is subject to interference, affected by other people using wireless and suck.
It is also unstable.

I recommend getting wired. Especially for BF4

Where does it say I have wireless? I have ADSL 5mbit cable which is enough for a game like this
