Radeon R9 270X help

Post by morcar »

I have a Radeon R9 270X and have installed the propriety drivers for my Linux Mint 17.1 distro.

I use Steam quite a lot but i have noticed that I dont even even half the performance I do when using Windows playing anything 3D with in Linux Mint.

For instance Team Fortress 2 I have to turn down the resolution to 720p and turn off some of the advance graphical settings or i get some very low frame rate from the game and this happens in most of the 3D games I play.

So my question is can I do anything to improve the performance of this graphics card on Linux Mint as I rather use Linux for everything I do.

Thank you for your time.

Users Dukenukemx and Condorman report better performance using the RadeonSI open-source driver in THIS TOPIC,
as do other users such as darkbasic in THIS WEB PAGE.

I would advise having a backup image of your Mint installation first because adding the Oibaf PPA and doing a distribution upgrade will upgrade a lot of packages.
I use Clonezilla.

To check the performance of the RadeonSI driver, I recently tested it against the radeon, fglrx (from package manager), fglrx (from Catalyst 14.12 package on AMD's website),
and nvidia-331 drivers, using glmark2. This benchmark for OpenGL runs 30 different tests and gives the FPS that the GPU is able to process during each test. The total FPS of the 30 tests
is added up and then divided by 30 to get the average, which is the final score given.

The systems used were an AMD A8-6500 APU with a Radeon HD 8570D and an Athlon II x2 with a Nvidia GeForce GT 730 2GB. The Nvidia card is a fanless, low wattage card.
The results were nothing to get exited about:
