PS4 3.50 Webkit Exploit from earlier today, PlayStation 4 developer OsirisX shared a video demonstrating Steam on PS4 (ARCH) Linux using the PS4 Radeon Libs on 1.76 Firmware.
To quote: Haven't tried on Ubuntu but works fine with ARCH linux after compiling both 64 bit and 32 bit Radeon libs. I posted a video of me running Steam a while ago. Most games have stable FPS when running low to mid graphics setting.
