I have been struggling to get Linux Mint 18.2 installed on my desktop for the past few days due to video issues. After reading tons of forum threads, I was finally able to get it running with the latest Mesa drivers via the "padoka" PPA. I have an Gigabyte X9-UD4 system with an Intel 5960X CPU running at 4.3GHz, 32G RAM, and an AMD R9-290x video card driving 2x 27" displays.
I tried installing the latest AMD Pro GPU drivers per the forum thread: viewtopic.php?f=59&t=248059 but kept getting black screens on boot. I removed the AMD Pro GPU and switched back to the Mesa driver. My concern is making sure I have the latest driver that gives the best performance. I downloaded the Heaven benchmark and only got 16-20FPS whereas Windows gets around 60FPS. I know there is a performance disparity between Linux and Widows, but this like a huge gap.
Thus, my question: how can I check to see if the video card is running at max capable performance? Output from "inxi -Fx":
