In BF3/BF4/Crysis2/Crysis 3 I get great fps with my 8350/r9 290 1080p... except my minimums. I've troubleshot drivers for hours, probably installed them like 20 times now with DDU and CCleaner.

CPU 51C, GPU 73C, CPU usage varies 50-70%, GPU usually 80-100%
Basically, I get appropriate benchmarks, and I get high fps in games, but Whether I'm on ultra at 8xmsaa or Low with No AA, I get the same minimum fps. It seems that my CPU spikes from 50-60% to about 80%, and my GPU drops from 85-100%, to about 30-50%... then returns to their proper levels...
When this happens, I see drops under 60 usually near low 40's in FPS... That should not happen with this good of rig. I'd be fine with lowering graphics, but it can't stay over 60, and the inconsistency is horrible.

No, its not all games, but most Modern titles such as Hitman Absolution, Far Cry 3, All Crysis, BF3/BF4, even Grid 2... Yes, they're hard to run, but why is my GPU load dropping? are these games turning my 8350 at 4.2ghz into a bottleneck? Even then, Why can't I achieve over 60fps on low, when someone with an i3 and a 650ti can stay over 60 fine on low...

For example, Crysis 3 on ultra and 8xmsaa was about 32-75fps the whole time, usually in the 50's. That's great for those settings, but on medium settings? I got 38-189fps... and it would Spike, causing a stutter in gameplay, and stay at 38-45fps for a bit in that area untl I walke a round a bit...

Could it be drivers? I VERY cleanly install:
I run AMD catalyst and uninstall ALL AMD software. restart
Reboot into SAfe mode and run DDU to clean registry and delete all AMD/ATI folders, reboot
Run CCLeaner, clean registry
Install Latest graphics (14.4 catalyst)
Install chipset 13.12
Install Asus MOBO latest chipset/usb/lan drivers...
problem persists...

I have updated BIOS, and unparked cores (does nothing on win 8.1 for me anyways)
Its a very solid build, and all info is in my signature, so I don't understand why it behaves like this. Please don't tell me to buy an Inte;, cause this 8350 should have plenty of power, and fps drops/bottles this big probably shouldn't happen.

Well not everyone has these issues it seems, and I have the tried many drivers. I'm currently in the most up to date as well.

then it might be the hardware itself.

Run furmark to chcek the GPU.

Run memtest86+ for multiple times, preferably over night, to see if your RAM is failing

Maybe insufficinet PSU power or its just faulty? Maybe MOBO?

There could be so much different stuff, that you have to eliminate it all 1 by 1.

CPU is stock OC, so is GPU. I ran MSI's Kombuster for 2 hours set at highest settings in GPU burn in. 100% usage whole time, got to 80C, but ran flawlessly...

RAM set to factory default 1886 and correct timings. I've tried others set of RAM, same results.
Should have enough power, and dunno why psu could be causing Performance hits... I have NEVER had a random shutdown, and 850w should be plenty. Voltages NEVER spike, the parts aren't losing power, just cpu gains usage, GPU drops usage...

That's what
I suspect too, as my hardware seems fine. I've messed with software os much though, and fresh installed once already :/
Might have to again...

If GPU usage drops, it is clearly a CPU bottleneck. Whether or not you can fix the CPU bottleneck is another issue, but on multiplayer, most people get drops below 60, even with faster CPU's than you. It may not happen all the time, but it happens and don't take every Tom Dick and Harry at face value. Most people tend to fudge their results, and ignore those few dips.

That said, this complaint shows up almost daily on these boards, and it seems most are using AMD CPU's, the majority being 8350's. The only time I've seen anyone of these 8350 owners have success in improving their situation, it was due to their motherboards northbridge overheating. They fixed it with a fan blowing on it.

As far as Overheating Mobo heatsinks, I've only seen one person on this forum list that as a solution... how many times have you seen it? I have 7 case fans in my PC... and in a wind tunnel configuration...

I know, looks exactly like a CPU bottleneck does it not? thing is, 8350 aren't suppossed to be bottling, and if it is, I'd think it would hold its ground better and not drop 30fps... I should oly be 5fps or so behind a high end i7...

I've ready through at least 10 of these threads, all CPU bottleneck issues with 780(ti)'s and 290(x)'s with 8350's, and they never get the result they want. It is always a CPU bottleneck, and they won't believe it and never find a solution.

You'll be the next person to go on for pages, and not finding a solution, most likely. I don't have BF4, so I can't tell you my experience, but there is something funny going on with the game and 8350 users.

8350's are considerably slower than i7's, but most the time it doesn't matter as most the time you are GPU bound. The 8350 does well with it's 8 cores (not quite full cores), and as a result does well when an app takes advantage of it. They are also reasonably fast that if a game isn't CPU bound, they show to keep up. The problem is, not all games are well threads and GPU bound. In the extreme examples, the 8350 falls quite far behind.

That said, BF4 is supposed to be pretty well threaded, so in this example it shouldn't be far behind. But like I said, I see 8350 users on here all the time complaining about this issue. There may be other issues at play. Maybe they see bottlenecks with slower memory, or maybe there are motherboard issues.

Nope, uninstalled afterburner a while ago. Only using GPU-z/Cpu-z...ingame overlays as well... You probably run it so much faster cause of your OC. Did unparking really help you? what fps you get on ultra 1080p?

unparking doesnt really do a lot for max fps maybe a little bump but does help with minimum windows 8.1 is ujnparked automatically but win 7 is a different story. ok lets look at a few things that card is not meant to be playing any new title at 8xmsaa for the most part you should be trying for 4xmsaa in most everything. But before that could you go into bios and turn off cool n quiet and tell me if that helps.

also just so you know even the mighty 3960 has drops in games was using one the other day look up some videos with high powered gear and games with fps and you will see all have frame drops if you are dropping in the 45 area thats completely normal heck look up the 4770k and 780 ti running those games in multi player and its never constant. If you want to see your cpu have a problem play ps2 thats what a bottleneck looks like.
this is a system that is awesome 4770k with a 780 ti and you will notice the fps are exactly what you are seeing

Yes, I know every system will have its drops in BF4, but mine happen too often, more then I think they should be. I already have Cool n' Quiet and all other power saving settings off. I know, I'm on 8.1, so un-parking did virtually nothing :/
I will say however, that a 4770k and 780ti would barely ever drop below 60, and that Crysis 3 video you sent me is pretty invalid in this case... you know that game hates Intel/Nvidia right? my 8350/290 run it better. look at this:
http://youtu.be/IgrAP2_GfOo?t=4m29s
Logan's rig has 4930k and 780ti superclocked, and Pistols's only a 9590 and a 290x Tri-X... yet 780ti wins in every other game ,by 10+fps.

Anyways, try and find a 4670k or 4770k with a 290/780 drop, cause I NEVER see anyone drop in videos, and they're losing recording as well... BF4 is not a hard game to run, so I hate that mine drops... it really shouldn't that often, like once a match maybe

OP is not only getting fps drops but GPU usage drops. Which drive is your game installed on?

Have you noticed it happening when you are near a save point or walking into a new area?

I noticed you have an HDD. Take a look at this video: http://www.youtube.com/watch?v=PriMnhNf56s

It is one of many that shows skipping due to seek time letencies on HDDs, which get dramatically improved from SSDs.

The problem doesn't translate over to an average fps rating in any clear way. It's just something "skippy" or "jittery" you notice that disrupts your suspension of disbelief, breaking up your mental connection to the game's virtual environment (i.e. it's annoying). Check whether what you are seeing is similar to what the video depicts.

Railway is no problem though, what FPS do you get in heavier maps? I see FPS issues mainly in all DLC maps, Hainan, Shanghi, and Paracel.

Yes, I see that, but that doesn't translate to Frame drops. I'm dropping physical frames to like 40-50 at times, not just little jitters between frames over 60...

You don't understand, Crossfire 290's only have a 105% ratio in Crysis 3, it runs bad on everything... Nothing can keep Crysis 3 over 60, I know that.

I'm ONLY worried about BF4, as it seems to run flawlessly on everyones rig but mine. The fact that 7950/7970 are running faster than my 290 is a BIG problem, and I need to figure which part is causing the low performance. I still suspect the game doesn't like the CPU, since I run every other game like I should be...

Have you run your CPU stock on BF4 before? How much worse were your framerates in BF4?
