7900XTX - varying utilization for same tasks

[K_B_A]

hey everyone, i am having some issues with my 7900XTX with very weird GPU utilization varying from day to day running the same tasks.

lately i have been playing alot of Path of Exile and i have noticed my GPU utilization varies from day to day by a significant amount.

i have done some testing both with OCCT & AMD Adrenalin open to check utilization %, one day the card will sit at around 40-45% idle ingame, next day it can be using 60% at login screen & idle ingame.
the card have a 0 RPM fan configuration, but the days the card is acting up the fans will run constantly, despite the temperature being below the threshold, untill i close the game agian.

before posting this i tried running the game with directX 11 & 12 idle both at login screen and ingame, the card would stay at around 60% and sometimes jumping to 80-100% or even to around 40% randomly.
the only "fix" i seem to have found is restart the game and pray, sometimes i even turn off the power supply and unplug the entire PC for a sort amount of time to "fix" this.

the attached picture is from standing ingame doing nothing, like mentioned earlier in this post when the card is running like it should the game only uses between 40-50% depending on what is happening ingame.
i have the same background applications running as any other day, Discord (hardware acceleration off), iCue & steam to run the game.

EDIT: i forgot to mention that i can easily notice this without having any monitoring software open, because at around 60% there is a slight noticable coilwhine, therefor it is easy for me to know when it is not running like it should.

my system specs are:
CPU - 7800X3D
GPU - Powercolor 7900XTX Hellhound Spectral White
MOBO - Asus Rog Strix x670e-a
RAM - 64gb Corsair Vengeance 6000mhz (EXPO2 profile)
PSU - Corsair HX1000i 80+ PLAT

my GPU is undervolted to 1080 & clock speed is limited to 2525 due to coilwhine, i am positive the card is running stable at these settings because i can run Horizon Forbidden West for 3+ hours with the GPU running around 90-100% both Utilization & D3D usage.

do these utilization fluctuations cause any fps problems or lags? if not everything is fine

nothing really noticable, only thing that seems to be different is when starting the game, it takes a few seconds to get stable at 60 fps.
i just dont understand why it can vary up to 20% and the "normal" days on login screen the GPU wont even be above 30%, something just seems off to me.

what game? could be some settings or shader compiling or something

Path of Exile, i have been running the game for around 40-50 hours the past week with this card with this happening from day to day.
just tried running the game for 15 mins, still the same, the card is sitting at 60-65% while playing meanwhile other days it is around 45%.

EDIT: there are some graph ingame showing different information that you can see on the picture, while the game is showing no shader the GPU is still sitting at 60%+, this is while standing still in game doing nothing so no real effects on screen.

I mean, what do you expect on capped 60fps?

 

the card is clearly not trying to produce as many frames as possible, the game clearly has Vsync or framerate capped at 60, which isn't bad,

 

if anything it's good that a high end card isn't struggling to deliver 60fps capped, if you see different utilizations it's only because of the effects since standstill with no effects is probably easier to render for the GPU

i have the game capped at 60 fps and Vsync off yes.

but now i just tried clearing shaders in AMD Adrenalin and restarting my PC, now the game runs below 60% and the login screen was only at around 30%.
despite adrenalin still showing some weird spikes, i assume this is just because it isnt able to monitor this 100% correct, that is a VERY large difference even when it has to reload the shaders.

this is standing still at the exact same spot like before but where the card ran 60%+

I see no problems with the utilization, when you move or not, the task the GPU does changes it's difficulty, which results in different utilization,

 

if I asked you to walk at a constant speed, would you walk at a constant speed all the time, or would you sometimes have to use more/less effort because of hill, random rock, something you don't want to step on/into like a hole, etc.
