Hi guys, I'm a PC guy, have built many systems - but this one's driving me insane.
I don't have loads of components around to do testing but I'm having trouble figuring out why this pc is performing so badly in games when none of the individual components seem to be under any sort of heavy load.

Symptoms: Running CoD AW at native resolution, everything lowest setting or off I get jerky non-responsive gameplay. It's much better than if I set everything higher, but with my setup I should be able to run at at least medium and it's only smoothness I'm after with higher framerates than 15-20fps. Also takes an age to load a map and I'm never in before it's already begun with people having been killed already....
Same thing happened for Titanfall when I played that.
My laptop runs CoD better than this PC.

System:
Win8.1 16Gb ram
AMD FX-8320 stock clocks
1Tb hybrid HDD for OS 50% free
256Gig samsung evo 840 running paging and cod - 55% free
R9-270X 2gig gfx running catalyst 14.12
I've not done anything silly like buy a cheap MoBo or PSU (can't remember make but it was appx £60 for the PSU)

I've tried MSI Afterburner, CrystalDiskMark, moving the game to a new HD (The SSD), moving paging file to the SSD from main hdd, running burn-in tests on the GFX card (ran fine no artifacts), and I'm running out of things to try.
Can anyone point me in the right direction on where I should be looking for my PC's bottleneck?
Can it be as simple as re-installing Windows (this is an upgraded from Vista originally installation).
Thanks loads.
Sam

Its not a brilliant board for an 8 core - I would just disable all power saving features & turbo/boost mode in the bios.

You shouldn't be having any problems with an 8320 in advanced warfare - its a very well optimised game.
I reckon the blame stands with core throttling of some sort.

Thanks for the quick reply. CPU usage in game is low, i've had resource manager running with all 8 logical CPUs.
GPU temps are about 60-65 deg C, have tried using MSI Afterburner to run fans on full incase of overheating but for some reason it's not pushing the GPU if that is indeed the bottleneck.
MSI 970A-G46 mobo, can't tell the PSU without taking case apart - and indeed the PSU could be at fault but it doesn't feel like that because I get none of the usual PSU issues when running burn-in tests to the machine.

Open up the side panel of the case and see if there is a sticker saying what the psu is without moving it.
The gpu temps are fine, you do not need 100% fan speed. Under 85C is fine.
You could try to reinstall your gpu drivers.

I'm kind of wondering if the GPU is faulty or isn't being used to it's fullest extent by the drivers, so I'm looking at the BETA driver set at the moment will let you know how it goes.

I did take the side off and the PSU is mounted bottom of case, I'd have to unscrew it to see the sticker. I believe it's a corsair but can't remember the specs. Drivers doing at the moment, will let you know.

OK new drivers and went back into the game with "optimal video settings" selected this time.
Ran MSI afterburner during and took a screengrab after a match but not sure if I can upload a pic.
Basic results: GPU temp - 62 deg C constant, gpu usage fluctuating between 15-45 percent avg at about 30, framerate avs 20fps, dropping to 10 at frequent times.
Mobo temps between 45-60 deg
cpu temps between 25-55 deg
cpu load 95% during map load then appx 60% during match
gpu clocks stock and 62 deg temp

well after much playing around I've OC'd my CPU. Which isn't advised using this mobo with this CPU, but it's behaving a hell of a lot better. I never would have thought that it would affect things so much, at stock speeds.... I will do some more checking but think I might need a cpu upgrade. ... any ideas what would be better than an 8320 for my mobo? :p or is it just buy intel at this point? ;)

Well a R9 270X is expected to run around 30fps at ultra.
COD:AW isn't optimized with AMD FX 8320.
Isn't your OS installed on your SSD?

Hi,
well running at 4gig OC, just with multiplier, I now get 60+fps on high settings. Bottleneck being CPU or as Madmatt30 says maybe some throttling. OS not running on SSD, since I've had no probs with the OS just with games :p
That's a massive difference. 10-20fps on low settings at stock speeds, 60+ fps with high settings on a 500MHz increase...

I wanted to pick both of you as the solution for helping so much.
Thanks both!
