gpu never 99%

Emrek127 · Dec 3, 2016

Hi! I have a problem with my pc, but you first need to know my specs:

MOBO: ASUS M5A99FX PRO R2.0
CPU: AMD FX-8350 Black Edition 4.0 GHz, 8-Core, 16 MB
CPU Cooler: Cooler Master Hyper 212 Evo RAM: Corsair Vengeance Bk DDR3-1600 DC - 8GB
GPU: ASUS GeForce STRIX GTX 960 4GB
PSU: Corsair VS550 V2 550W

My GPU Usage never hits above 90% when i play games? It's soo annoying! My FPS Is too low then! In GTA V on Normal-medium settings 1280x1024 Resoulution!

On every game i play the gpu usage is low and low fps! Plss help!

Are any CPU cores/threads hitting 100%?

something is bottle necking, usually it's the cpu not being able to keep up but for 8 cores and 4GHz there's no reason for bottlenecking there... Although ram can do it too. 1600MHz should be enough, is it dual channel or single channel? Also if you have faster ram somewhere that you aren't using try it just to see.

Well those cores have a very low IPC by todays standards. That CPU is generally beaten by an i3 6100 in games. Hence my question.

1280x1024 is considered a relatively low resolution as far as graphics cards are concerned. Your GPU doesn't need 100% to generate such a low number of pixels. It has rendered a frame and is waiting on the CPU to take it, display it, and give the GPU more data for the next frame. What is your CPU utilization while gaming?

well you could be right. i dont use amd as iv'e only used i7 cpu's from intel

sizzling :

No my cpu is not hitting 90 or above

Emrek127 · Dec 3, 2016

sizzling :

Only when im stress testing

camwhit :

Its running on single channel

Emrek127 · Dec 3, 2016

clarkjd :

Around 35-70

70% CPU usage almost certainly means one of the cores is near 100%. It only takes 1 core to bottleneck you. If you turn up the settings, do you see a decrease in performance? If not, that is just another sign that something else if bottlenecking you.

Even when i play on Low/medium/high the fps doesent change! It's just the same Fps!

Emrek127 :

Classic CPU bottleneck. When you reduce the load on the gpu (lower the settings) but your fps stay about the same that means something else is limiting performance and that will most likely be the CPU. Are any CPU cores hitting 100%? Overall usage is not that important.

Emrek127 :

Lowering settings does not help your GPU hit more load. Reducing graphical settings, reduces the load on the GPU at the same FPS. The CPU, on the other hand, doesn't get much if any reduction in work in relationship to the drawcall thread. That is why I said to increase the settings, not lower them. This will put the GPU to work.

You are at your FPS limit with your system. The best thing you can do, other than replacing your motherboard and CPU for a faster one (Intel), is to increase your graphical settings so you put your GPU to use and increase visuals.

The CPU Only hits 99% or above when im stress testing! but in games its not hitting

Can it be because of i didnt update the motherboard yet?

You keep saying "the CPU", when we talk about "a CPU core". Those are not the same thing. The CPU usage, adds up all 8 cores on your CPU, but it's the single CPU core, that the draw call thread is on, that will bottleneck you. You can have 12.5% CPU usage, with a single CPU core at 100%, that is bottlenecking you in the most extreme cases.

My cores are stable i think

bystander · Dec 4, 2016

What ever the case, you are bottlenecked. It's most likely related to your AMD system, and not your GPU. Whether it's the motherboard, RAM or CPU, that is almost certainly the issue. Your FPS are good for GTA V, so you don't really have an issue in the slightlist. What it does show is your system is holding back your GPU, which may be more than you need for your resolution/system.

Guys i don't think that the problem is AMD SYSTEM. I have an i5 4690k 4.40GHz & GTX 1060 STRIX with the same problems, GPU Usage 30-70%(rare) with some fps drop.

Look this weird drop to 0% for 20s

bystander · Dec 4, 2016

What is that a graph of? And 30%-70% is better than your AMD system. The fact remains, you have a low resolution, and you have GPU power than your system can handle. That dip is most likely a load screen, as it is so flat, and exactly the same as at the end when you most likely logged out of the game.

The FPS you reported, is what most people get. Are you aware, that a bottleneck does not mean you are getting bad FPS, it just means that your system is out of balance at that given time. There is always a part that is holding back another, most the time it's the GPU holding back the CPU, but when you have too fast a GPU for your resolution/game/settings, that quickly shifts to the CPU or another aspect of your system.

This is graph of gpu usage when i play League of Legends, gpu usage 10-30% with a weird drops to 0%.

bystander · Dec 5, 2016

Ah, well, that's a load screen. Games have those. It's also a very low demanding game, and clearly CPU/RAM bottlenecked in the game during the game play.
