Sapphire TriR9 290 Inconsistent Performance, Wildly Fluctuating GPU Load, Bottlenecking?

Greetings to all, this is my native post, please bear with me,

I'm frustratedly confused. Here's the deal:

I have an
amd FX8350
16gb Gskill DDR3
ASUS M5A99FX PRO R2.0
Sapphire Tri R9 290
Win 7 x64 Ult sp1

I use a 42" Vizio Hd tv for a monitor, 1080x1920.

I've been out of the computer game for a lot of years, I still maintain a decent concept of theory but the details of some of the intricacies I am not yet fully aware.

I can't seem to achieve and maintain stable frame rates. I first really noticed this playing the Overwatch beta and since beginning Hitman in the last few days I have become even more aware of this issue.

It's like there's a gas pedal being pressed and released or a buffer repeatedly filling up and emptying or something. The speed of the game pulses, the frame rates fluctuate as well, but the frame rates and the speed of the game aren't necessarily intertwined...This particular issue was more prevalent in Overwatch than Hitman.

I have messed around with settings and unparking my cores, (cleanly) updating drivers, setting my system to turbo/performance mode, increasing the voltage limit on the gpu (that's the only "overclocking" that's done on the system anywhere)

It's not unplayable, benchmarking on recommended settings is around 30fps, but that's in between a low of 5 and high of 120 and very stuttery and pulsy. I just have an inherent belief that it should run smoothly and there's something I'm missing. But maybe not, maybe I need to up my processor...and that's fine, I just want to know!

The one piece of evidence I have is that monitoring with gpu-z while playing hitman, the gpu load is nowhere near consistent, it spikes wildly....which in my mind explains the pulsing of the game, but still am baffled by the cause.

Any help and or insight would be greatly appreciated! Thanks!



UPDATE 1: To the Folks below: none of my cores were maxed and it was at about 30% load overall I believe. Every setting I can find from BIOS to windows to Radeon is set to performance or turbo or whatever the opposite of power-saving is.

I've done some more fiddling and discovered V-synch smoothes things out however the pulsing is still evident. I did a couple of tests in Furmark and was running about 70fps in the 1080p burn in with 99% gpu load. I'm essentially convinced that the inconsistent gpu load while playing Hitman is responsible for the pulsing speed of the game I just have no idea what to do about it.

The responses are much appreciated!

turn off all cpu power saving features in the bios

like cool n' quiet


it might help, this is a well known issue with amd cpu + amd gpu

I forgot to add:

I have a Swiftech H240-X on the CPU. The temps are a little warm but nothing to worry about imho. GPU barely crests 60c and the CPU doesn't get past 53c.

And! I have a 750w Gold PSU, I forget the manufacturer off hand
