How to enable FreeSync on amdgpu?
by MirceaKitsune from LinuxQuestions.org on (#5SQ4R)
Following the breakage of my previous GPU I decided to buy a more modern graphics card today, just finished installing the newer model which I'm very happy with! The new card supports AMD FreeSync, so does my monitor, and I'm using a DisplayPort cable which I understand is the only connection supported by the kernel for now. Seeing I meet all the criteria, I figured I'd ask what it will take to ensure variable refresh rate is enabled. My new video card is an ASUS Radeon RX 570 ROG STRIX.
Unfortunately the only information I could find is the `xrandr --props` command, it indeed shows `vrr_capable: 1` for my DP connection so that's a good start. Capable doesn't mean enabled though, and I couldn't find the command to actually ensure that it is. When running a game in full screen (eg: TheDarkMod or RedEclipse) the monitor's OSD still shows a fixed refresh rate, I take it that means not enabled. Is it possible to turn FS on and give it a test, ideally without having to hack system configs and make permanent changes to files maintained by system packages?
