Is there a way to install the amdgpu-pro drivers for elementary juno to improve gaming performance? I'm new to linux and I'm trying to get a picture here: On how to improve the gaming performance and maybe even fix game issues with newer drivers. I know that the standard drivers support my 2x RX-480 but I don't know how good they do this.
I recommend the latest MESA drivers, you could add the official repositories:
sudo add-apt-repository ppa:ubuntu-x-swat/updates
sudo apt update
sudo apt dist-upgrade
They work very well in my case, even in games.
BUT if you want to install the proprietary drivers, you must make some modifications in the system.
First go ahead and download the driver from the official website (AMD).
You will need to edit the system file
on line 3 of ID=elementary to ID=ubuntu and on line 6 of VERSION_ID = "5.0" to VERSION_ID = "18.04"
if you are using Eos Juno (open "files" with administrator privileges for to be able to make the change).
Then CD with a terminal to the location of the driver and type:
(this installs the Base kernel, Accelerated graphics, Multimedia table, Pro OpenGL, Pro Vulkan, Pro OpenCL).
After installing everything correctly edit the system file /etc/os-release again, on line 3 of ID=ubuntu to ID=elementary and on line 6 of VERSION_ID = "18.04" to VERSION_ID = "5.0" to leave that file as it was before.
Works pretty good for me, but I prefer to stay with the open MESA drivers because native linux games on steam recommends MESA drivers with vulkan support. For mesa support on open drivers:
sudo apt install mesa-vulkan-drivers
