Odd Graphics Card Behaviour

[UK.evin]

HI everyone,

 

I've recently been getting poor and odd performance issues from my Gigabyte AMD Radeon HD 7970 graphics card. I first noticed issues with my graphics card about a week ago when I played CS:GO and Rainbow Six: Siege. In CS:GO I get FPS stutter/lag whenever effects are being displayed on and off screen (e.g a flashbang detonates behind a wall or door) and the sutter/lag lasts as long as the effect that is being rendered. Occasionally, when scoping in with an AWP/Scout and firing, the gun's scope will freeze for a split second causing shots to become off target. On rarer occasions, bursts of automatic weapon fire can lead to the same freeze effect as previously mentioned.

 

In R6: Siege, in some rounds my FPS will just drop to a ridiculous 5~, tremendously lagging mouse and keyboard inputs. I checked my Radeon Settings panel to view graphics card activity, core frequency, memory frequency and temperature. Temperature suffered no issues however, activity, core frequency and memory frequency sat at either 0% or an oddly low number (25%~). This number would fluctuate a bit and return back to higher activity and correct frequencies (FPS stutter/lag would be gone when returning into game window).

 

Here are my specs:

 

Motherboard: AsRock Z77 PRO4-M

Processor: Intel i5 3570K (Overclocked to 4.0 GHz)

Graphics Card: Gigabyte Radeon HD 7970 3GB (Windforce cooler)

Hard Drive: Standard Seagate 1TB 7200 RPM SATA3

Memory: 2x4GB Corsair Vengeance 1600 MHz

OS: Windows 10 64-bit (Latest build)

 

I'm using16.5.3 drivers for Radeon Settings. I've reset clock speeds on my graphics card to default and fan speed is on Auto.

Try reinstalling your drivers using Display Driver Uninstaller.

So I used DDU and reinstalled my drivers. It has improved in CS:GO but occasionally there still is the stutter when flashbangs go off. Rainbow Six still suffers huge frame drops now and then and forces me to ALT+TAB out and back in to "reset" it. I'm not sure if it's poor game optimization o or something else.

What are your power settings in the Radeon software, it could be getting stuck in a low power state or for some reason changing to a lower power state.

So here are 2 screenshots of my Radeon Crimson Settings. These are Global settings.

 

I researched a bit and found that Power Efficiency isn't supported by my card (HD 7970) but it displays as it being on. My card is definitely throttling between different states as you can see in the 1st screenshot it shows low GPU activity when I have Rainbow Six running in the background.
