Using Ubuntu 18.10 with AMD rx 580. Success. By using updated open source drivers from a ppa, the performance of PA increased. Nevertheless, there is still the use-after-free-bug, which causes wrong textures to be printed often. But its okay to play for me for now. Driver Here is the ppa for ubuntu I used: https://launchpad.net/~oibaf/ archive/ubuntu/graphics-drivers AMD RX 580, i5, 16GB-Ram, 4k My PA settings Virtual Textures: High Light: Uber Shaddow: High Environment-Darkening: Off Anti-Aliasing: Off HDR: On Resolution: 100% Mode: Fullscreen Results For now, I can recommand playing PA:Titans with rx580 despite the artefacts and lazy menu rendering. Until someone might come up with a better option. Video encoding Moreover, by using the newest driver, you can use hardware acceleration to encode a 4k live stream. You might reduce the framerate a bit more, because 4k h264 encoding with ffmpeg is still heavy despite hardware acceleration. I used the follwing command for recording: ffmpeg -video_size 3840x2160 -framerate 15 -f x11grab -i :1.0 output4.mp4 -hwaccel h264_amf -b:v 10K -compression_level 1 Audio Audio is working fine with standard pulseaudio setup. I use separate HDMI port for digital audio output to a AV Receiver for hq setup. Subwoofer for huge explosions outstanding
