RX6000 series GPUs poor performance not fully utilised SOLVED, I should say mitigated

[Gelf VXR]

So I have a Sapphire RX6800 refence card that has been plagued with poor utilisation in games (World of Tanks) and GPUZ render test. Also read many forum posts regarding the same issue, also an article in PC Mag I believe who found the same thing with some older game titles lacking fps.

Well I found a fix, which should lead AMD to the root of the bug, seeing as they haven't solved it since the RDNA 2 launched.

In GPUZ render test for example the core clock usually, utilisation and power draw are low. The fix, go to display settings, increase the screen scale higher (max), close the app (or game), reopen and run render test again and voila, full load and power draw is restored.

So many replies to various posts I've seen stating your game just doesn't need to push the GPU, yer right

Have you sent any reports of this to AMD directly?

What a weird bug.

Yeah, in order for GPU-Z render test to utilize the GPU better, you have to run full screen mode....

I don't remember having issues running RX 6800 XT. Ran DX9 through DX-12_2 benchmarks. Gave it to my brother for his ""Birthday Card"" and he uses it daily. Has not reported any issues, but he doesn't play the same games.

No, that’s not the issue, screen scaling setting is…..

Same test, only difference is normal vs 225%

And GPUZ render test is in a window, not full screen

I haven’t, but it seems they are already aware

Interesting. Never had any issues with a RX 6700 XT though I use the card more rarely these days.

The more its reported the better timing it gets addressed

What fixed stuttering and random framerate spikes in games for me

Hi everyone! this marks my first post here I was experiencing stuttering in every game. I have spent months trying to find a solution and had no luck. i couldnt even tell what the issue was and that alone was frustrating PC SPECS: - Ryzen 5 5600 PBO 4.65ghz - Radeon RX 6600 UV+OC -KINGSTON...

I’ve posted the issue to the AMD support forum

Thank you for the link, I have been looking into MPT, I tried his settings, the issue persists.

They just don't give a damn about RDNA2 anymore, precisely from the beginning of this year, just judging by the drivers alone. Reported or not, I'm afraid it won't be fixed.

Idk about that, I've reported issues when a product was out of production and it did get fixed, sometimes what can happen and this even includes same kind of setup that a CNR can occur.

But did you go through the software and report it for bugs?

I remember when crossfir was around you setup a profile, heck even oc software you could set a profile for a specific game and lock clock speeds in place

I will rarely see a similar effect to this in my 6600 XT and 6800 XT where it "feels" like the driver isn't loaded, which is supported by the observation that on occasion FPS will be lower than expected, then the Radeon info overlay will pop on and GPU utilization goes to 99% and FPS are great. And when I notice the lower FPS before the info overlay pops up, I'll hit Alt-R to bring up the Adrenalin overlay and then utilization goes up to max.

But this doesn't happen often, additionally I have 4 systems and this seems to happen more often on one of them and almost never (or never) on the others. So it could be a Windows or driver install issue.

I presume you did report your finding as well?

A long while ago when I first saw it. Wasn't sure what I was seeing at the time so my report wasn't great. Haven't seen it in a while though and was using the 6800 XT for a few weeks recently and didn't see any issues.
