Problem with Radeon R9 295X2 and 20.3.1 drivers

I have just installed the newest optional drivers and I lost all Crossfire capability which decreases my performance by about 50%.

When I try to turn crossfire on in Radeon Software the app seems to restart and the option goes back to off.

I also cannot choose a predefined profile for any of my games.

I have just installed Kingdom Come Deliverance and I am only getting about 40-50 fps.

Please help.

Re: Problem with Radeon R9 295X2 and 20.3.1 drivers

So far I have checked 20.2.2. I can turn crossfire on in this one, but there is no option to choose a crossfire profile.

I have also checked 20.1.4, in this one I also can turn on crossfire, but the only crossfire option for games is "off".

In 20.1.1 I can turn crossfire on, but once again for the games I don't have the option to choose a predefined profile.

It seems that the last driver version giving me the option to choose a predefined profile is 19.10.1

Re: Problem with Radeon R9 295X2 and 20.3.1 drivers

DX12 MultiGPU and DX11 CrossFire "support" is a joke term in Adrenalin 2020.
If you have more than 2 of same GPU on your system you cannot choose which to pair up.
DX11 Crossfire "AMD pre-defined profiles" option is still missing in Adrenalin 2020 20.3.1, although Disabled. Default, AFR Friendly, Optimize1x1, and AFR Compatibile are there. 

Did you try Adrenalin 2019 19.12.1?
If not, please DDU in safe mode diconnected from the internet to wipe Adrenalin 2020 from your PC and install Adrenalin 2019 19.12.1.

Once that is installed you can download a fresh copy of Adrenalin 2020 20.3.1, extract it under C:\AMD and then use Windows device manager update your primary AMD GPU Driver using "Update Driver" and point to:
C:\AMD\Win10-Radeon-Software-Adrenalin-2020-Edition-20.3.1-Mar19\Packages\Drivers\Display\WT6A_INF

That should give you Adrenalin 2019 19.12.1 GUI/UI with all of the Crossfire Profiles and Options.
You Get Global FRTC independent of Chill_Max. 
You get a working Game Advisor via a simple and easy to use Radeon Overlay that does not report "Horse Manure Data" and spread it everywhere you look in the GUI/UI.

But you use the new Adrenalin 20.3.1 drivers.

We shouldnt have to do this with AMD Drivers.

"All aboard the Electric Mayhem Bus".

Adrenalin 2020 delenda est.

I did everything like you said. I have the old UI, I have the option to choose a predefined profile, but I got no profiles to choose from.

OK, I will install that Hybrid Adrenalin 2019/2020 GUI/driver on a system with Radeon Pro Duo as primary GPU on PCIe 3.0x16 slot and see what happens.
Might be a few days before I can post results to you.

Awesome, hopefully you will find a solution. Thank you for your help.

With older than 20.3.1 drivers installed, when I picked the AFR option for Kingdom Come it gave some minor performance boost but also heavy flickering.

At the moment with the hybrid drivers I have all the options available but like I said there are no profiles to choose from and also any crossfire option I choose seems to make absolutely no difference in game.

Here is a system with a pair of RX Vegas and an R9 390x attached and active.
The Vegas are in Crossfire.
Driver is Adrenalin 2019 19.12.1.
Crossfire options available for BF1 are shown:

I reboot the PC and open Radeon Adrenalin 2019 GUI after Driver Updates:

Here are the Crossfire Settings available for BF1:

Anh all of the profiles are still there:

So for a pair of RX Vega it is all there and working.

I will go fit a Radeon Pro DUO to another machine and see what happens.

OK?

Bye.
