Please also bear in mind that the driver was never meant to be the "support all GCN 1.0/SI" release, at least to my knowledge. The full extend of what hardware is supported is in the release notes, as always. Same goes for newer Kernels; don't forget that it's the Pro driver, hence it supports the stock kernel of the latest Ubuntu LTS release. That's always been the case thus far, and 16.50 was never going to be any different.
As for new features (like Freesync, for instance), we're working on ways to be more transparent and informative about what they are, how they work, how you can enable them (when it's not a matter of "always on") and if they have any limitations in their current implementations.
I also didn't realise I only have two posts in here after almost 10 years

The harvest configurations are chosen based on (a) what would be a good product positioning relative to the full-die part, and (b) what would be an expected number of CUs etc... to be defective. The driver needs to set the chip up a bit differently (we have logic on the die to handle fusing off blocks) and power is not consumed by the fused-off blocks, but otherwise they work exactly the same.
I'm only guessing so far that the issue is full-die vs harvest configs; that's just the best-fitting pattern from the test results we have so far.

The "TearFree" option struck me as something that would be worth removing from the conf file (along with freesync)... that's just a guess though.

Ok I spoke too soon. I did a fresh install of Mint 18 MATE 64 bit and get the following error after entering this command into the terminal:
xrandr --output DisplayPort-0 --set "freesync" 1
X Error of failed request: BadName (named color or font does not exist)
Major opcode of failed request: 140 (RANDR)
Minor opcode of failed request: 11 (RRQueryOutputProperty)
Serial number of failed request: 43
Current serial number in output stream: 43
I also tried to add an option to usr/share/X11/xorg.conf.d/10-amdgpu-pro.conf - this is my current state of it. (I got the idea from TearFree option):
Section "OutputClass"
Identifier "amdgpu-pro"
MatchDriver "amdgpu"
Driver "amdgpu"
EndSection
Section "Files"
ModulePath "/opt/amdgpu-pro/lib/xorg/modules"
ModulePath "/usr/lib/xorg/modules"
EndSection
Section "Device"
Identifier "Card0"
Driver "amdgpu"
BusID "PCI:1:0:0"
Option "DRI3" "1"
Option "TearFree" "on"
Option "freesync" "on"
EndSection
Nothing worked. My monitor refresh rate is not changing in the monitors OSD menu, when testing with the Witcher 2 or Metro 2033 Redux on steam.
If you can help I'd really appreciate it.

Thank You! That was exactly what I was looking for. Though having to enter this command every restart is kind of a pain in the rear.

OK, found it:
Enable/Disable FreeSync:
To enable FreeSync, run the following command:
DISPLAY=:0 xrandr --output DisplayPort-# --set "freesync" 1 (the "DISPLAY=:0" part is normally not required)
Where # is your display's number (e.g., DisplayPort-0).
You can check what enumeration your FreeSync display receives before hand by entering the same command used to check FreeSync status. (not sure what that command is, but will find out)
Limitations for FreeSync 1.0 for Linux:
For FreeSync to work in OpenGL and Vulkan applications, V-Sync must be turned ON. If V-Sync is OFF, flipping may not occur hence FreeSync will not be engaged. If the individual application does not have V-Sync options, you can set it globally by modifying /etc/amd/amdrc (change the parameter from 1 to 3)
FreeSync should not be engaged on desktop or video playback
FreeSync enable setting is set on a per-display connection basis
FreeSync enable setting does not retain after display hotplug or system restart (e.g., need to manually re-enable FreeSync via terminal command)
In multi-display configurations, FreeSync will NOT be engaged (even if both FreeSync displays are identical)
FreeSync via HDMI is not supported for this feature. Only DP FreeSync displays will work.Last edited by bridgman; 11 December 2016, 01:04 AM.

I Installed it but my games did not make use of Freesync automatically. Do I need to edit some file? I have an R9 Fury and a Freesync monitor of course. I can't seem to find anything related on google or youtube.
The apps that were tested were:
-Unigine Valley
-Unigine Heaven
-Metro Last Light
-Civilization 5
-Witcher 2
-DOTA2
-TF 2
-Counter Strike Source
-Rocket League
-Ark Survival Evolved
-XCOM2
I have a nagging thought that FreeSync also requires relatively recent HW (maybe CI and up) but Fury should be fine.
EDIT - any HW supported by DAL should apparently also support FreeSyncLast edited by bridgman; 10 December 2016, 10:18 PM.

Played TF2 for 2 hours today. Performance was good, similar to mesa (which is the same as Windows').
