They have no intention of bringing it back as a separate control.

Just use MSI Afterburner Rivatuner Frame Rate limiter or wait until someone writes a decent GUI/UI for AMD Drivers like in the old days.

Re: NO "FRTC" Frame Rate Target Control with Radeon Software 20.8.1

Hi !

You're right, but it's stupid in fact (the decision to removed, not you of course ^^) ... they removed one function which was working great, everytime, everywhere and without any issues, and useful "everytime" (unlike some that they have added in the meantime, like the integrated browser for exemple, which isn't something essentiel, all launcher have already one in their overlay) and that will obligate us to use a tierce one, on one another soft to get an identical function, even though there was one was integrated before.

Even tough nVidia add one in their driver at the moment where they removed their.

This decision makes no sense. At all.

Like the author of the thread (and many other) , I'm expecting they bring back the function.

It's not like to ask for a new function, this one already existed. The load of works to put it again isn't really big so ...

I didn't make, as some other, any definitive update of driver since the change of UI/delete of FRTC ... Tested some version, but always come-back on 19.12.1 to have FRTC.

Maybe it's like fighting against windmills I suppose, but at least if one guy is continuing to try to change by creating thread (It's not a lot, but they're not lot of solution, so), maybe at long-term we can expext something.

It's my 2 cents. Hope that can helps...

If you just want FRTC function alone, just turn on Radeon Chill and set Chill Min = Chill Max = 59 for example.

That should work.

Hoerver if you want to use FRTC with Chill or FRTC with Radeon Boost, you can't using the GUI.

Since AMD remove the Global FRTC slider and tie FRTC to Chill Max you are stuffed if you want to game with Chill and not turn in game VSync on.

No, they need to think bad drivers.

Re: NO "FRTC" Frame Rate Target Control with Radeon Software 20.8.1

Yeah, but no ... I know we have to use Chill : but sadly, it's not work so fine as FRTC. And that the problem, and why we regret the lose of FRTC.

Chill don't replace it entirely : it just not working on some game-menu for exemple, or can create stuttering in game too (anyway, I xperimented sometimes with it). And on some games, Vsync not locked totally fps (DooM 2016 for exemple).

With FRTC, I never had any problem, it was just working everytime, and fine 😕

Anway, it was what I observated when I used the both ...

Maybe I'm wrong and don't interpreted correctly your third sentence : but you told they're a way to enabled it without using driver's GUI (editing a files maybe ?) ?

If it's true, I'm interested !

Anyway, for me It's probably nothing for them to put it again ... except a few time to reinteger it, but it's probably just a short time of works (don't know how much, I'm not dev ^^), because the function existed before ...

Yes I know. I agree with you. I protested loss of  FRTC, but the response from AMD is "turn on chill, set Min = max".

RE: Chill don't replace it entirely : it just not working on some game-menu for exemple, or can create stuttering in game too (anyway, I xperimented sometimes with it). 

Agreed.

RE: And on some games, Vsync not locked totally fps (DooM 2016 for exemple).
Sure.

RE:

I have been running BFV and other games with VSync Off and using FRTC to keep 1-2 FPS below Vsync range and it workks great. Also used FRTC with DX111 CrossFire and DX12 MGPU.

RE:

If it's true, I'm interested !

There used to be a registry entry to re-enable FRTC in Adrenalin 2020. I cannot remember the variable right now.
The FRTC function is still in the drivers. They simply tied FRTC to Chill Max w/o thinking about it enough, just so they could remove one additional slider.

"Yes I know. I agree with you. I protested loss of  FRTC, but the response from AMD is "turn on chill, set Min = max"."

It's not the first thread I read, and I saw you protested too ... So I know a bit your position about that.

But I'm frustrated, I supposed, about the remove of FRTC, that why I'm a bit annoyed 😕

"I have been running BFV and other games with VSync Off and using FRTC to keep 1-2 FPS below Vsync range and it workks great. Also used FRTC with DX111 CrossFire and DX12 MGPU."

Me too, I did the same !

My screen is a 75Hz (and Fressync), so I put 73fps max and ... everything worked fine !

In fact i used it with all the game I have ... and also on old one so, which was great because that aoid to have xxxfps for nothing (for exemple, I don't need 150fps in Medieval 2 Total War, and that allowed to don't use VSync, as you told).

"There used to be a registry entry to re-enable FRTC in Adrenalin 2020. I cannot remember the variable right now.

I found it ! :

- KMD_FRTEnabled

- KMD_MaxFrameRateRequested

I found it (thx Google) on a Reddit thread.

So, I tried to modify the registry without doing nothing more, and that doesn't works.

By following more instruction in the Reddit thread (and a second one quoted in the first post), I uninstalled with DDU, modify the key after install just the driver with "Device Manager" (as explain in the quoted thread) and reboot ... but that doesn't works again 😕

I suppose I missed something ... a complicated story for a simple function ^^'

PS : sorry for the long time between my answer, I didn't have lot of time to answer ...

Re: NO "FRTC" Frame Rate Target Control with Radeon Software 20.8.1

No problem.

I did have FRTC working using a registry setting in Adrenalin 2020.
I will check if it was the same one later.

I am currently running with Hybrid Adrenalin 2019 19.12.1 GUI/UI and 20.8.1 driver install
So I have FRTC at the moment and it works:

Maybe you should try that?

The best perforrming Frame Rate Limiter is Rivatuner though, so you could try it with the above Hybrid driver install.

If you can put up with Adrenalin 2020 GUI/UI and 20.8.1 driver and its drain on CPU resources (7-14% of a Ryzen 2700X on Windows 10 Pro 19.09 ) , you could try using Rivatuner with it.

Re: NO "FRTC" Frame Rate Target Control with Radeon Software 20.8.1

It's even better !

I prefered the "Crimson" look as the "Adrenalin 2020", so it's double win !

So I tried, and succeed, to apply old UI with 20.8.1 ... But I'm not sure it's the best way to do :

I installed all the 19.12.1, then I run the new one and stop when he asked to install.
With "Device Manager", I selected "Updated driver" and selected the new folder to update.

After reboot, I have Crimson UI, but the 20.8.1 installed !

Of course, I tested, and it's works !

Anyway, thanks for the tips !

But, maybe it have a better solution/way to do, I suppose ?

I didn't notice a higher load for my CPU (I have an i7 3770k and I'm under W10 2004, my graphic card is a RX480), but maybe a bit higher RAM load ... but I'm not sure to be honest ...

Anyway, an other good aspect with FRTC is to avoid to use a tierce soft, and have an integrated and esay solution, even if it's not the best (but stay close to perfect in my case !)

For the registry key, I put the way (I used and found on Reddit) on the screenshot linked ^^
