AMD removed Power Efficiency toggle from Adrenalin 2020

Without that toggle available my card keeps rising his GPU clock without any need and thus drawing much more watts and generating much more heat. I'll keep using the Adrenalin 2019 version until AMD fix it.

Re: AMD removed Power Efficiency toggle from Adrenalin 2020

I agree, but we require this feature because the GPU is downclocking causing severe stuttering and lag.

It worked on the FuryX but looks like it was removed on newer GPU's.

AMD put back the feature please.

Re: AMD removed Power Efficiency toggle from Adrenalin 2020

So your Fury X card does "Power Efficiency" by default and enabling it on Andrenalin disable it? Funny, mine is an RX480 and works the correct order. Power Efficiency indeed can cause some stuttering due to the miscalculation of the necessary clock for a given load, it usually works better under Windows 10 than Windows 7, and is perfect to maintain the card cooled and consuming only the necessary amount of power without cost performance loss on most games, specially if an FPS limit is enabled (tested with Adrenalin 19.9.2).

Re: AMD removed Power Efficiency toggle from Adrenalin 2020

I don't have the old Fury X anymore but I had the "Power Efficiency" option available in the Global settings panel.

I have always disabled the "Power Efficiency" setting to keep the core clock speed as high as possible.

If you enable the "Power Efficiency" setting, the core will dynamically downclock.

We own the VII now and the "Power Efficiency" is completely missing from the Global settings panel.

In 4K 60hz games, the VII will downclock to 130mhz, its stupid and AMD didn't test anything.

Re: AMD removed Power Efficiency toggle from Adrenalin 2020

In mine rx480 that feature is disabled by default, but if in yours it is not, its more one reason for AMD to put it back. If AMD don't want "gamers"  to enable it by accident and blame for loss performance, they should put it somewhere, even if we needed to activate by change some regedit value. Have you already tried to disable (in your case) by regedit key?

Re: AMD removed Power Efficiency toggle from Adrenalin 2020

I agree, we need this feature back asap.

Also I have edited so many values in the registry, no luck I'm afraid, if you can help us, please be our guest, see what you can do here.

I cant find the value in the registry?

Without the "Power Efficiency" option, the VII is a dud just like the FuryX back in 2015.

Re: AMD removed Power Efficiency toggle from Adrenalin 2020

Here you go:AMD GCN POWER_EFFICIENCY_ADRENALIN_19.9.2.jpgThis is what change in registry when I disable the toggle under Adrenalin 19.9.2. Location is: HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\{SOME-CODE-OF-YOUR-OWN-CARD}\0000 and the key affected is PP_CNEscapeInput. I don't have the 2020 driver version, so try it and give the feedback if it works for you.

I emailed then asking for that feature back here, we have to pressure AMD: https://www.amd.com/pt/support/contact-email-form

I think they just abandoned the feature like they don't care about efficiency in their products anymore or to support those who have it embedded on driver and want to disable.

Hello and thankyou very much for the reply.

This is brilliant, absolutely spectacular find there, Ill report back ASAP, see if it actually works for the VII.

I'm sure many AMD users will highly appreciate this.

Also we have indeed contacted AMD directly regarding the missing Power Efficiency and still awaiting a response.

Thanks again.

Re: AMD removed Power Efficiency toggle from Adrenalin 2020

There's a difference about the location of "01" with the same driver on Windows 10.

And when I let Wattman with their default, stock settings, became more easy to find the
"01". So basically that key is the Wattman settings, wich is also dangerous, since modifying it can change the graphics voltages, clocks, etc...

But one thing remain the same. In that specific graphics and driver, the hexadecimal of PE "01" is always 4 commas after the "0c".

Re: AMD removed Power Efficiency toggle from Adrenalin 2020

Thanks for the update.

Unfortunately the strings are completely different on the VII, I sent you a message with the edits.

Thanks again.
