Freesync broken 2019 megathread
Posted: 28 Jun 2019, 10:31
Freesync is broken for me with current drivers, seeking for users with same problem.
Correct Freesync behaviour:

What happens:
Anything that isn't AMD FRTC will break freesync, producing this behaviour:
https://www.youtube.com/watch?v=4vNbAACtlcw RTSS cap to 43 fps
https://www.youtube.com/watch?v=6ret-aP-OU0 in-game engine framelimiter 30 fps
using Chill minimum will break freesync, in-game framelimiter will break freesync, rtss will break freesync, probably fraps and anything else will break freesync.
Now something interesting.
If you use RTSS cap first, alt tab into the game and then use the overlay to FRTC to -1 fps of your target framerate and then put the slider to the exact RTSS cap (example RTSS 50fps > 49fps FRTC then 50fps)
This happens:

Perfect framepacing, perfect refresh rate at the expense of severe input lag (FRTC).
Does now FRTC do a good job of framepacing when paired with freesync regardless of what MSI AB OSD shows? .
Is basically the advice of using freesync on + vsync on + RTSS 142fps now obsolete? How to achieve perfect image and frametimes with least input lag now?
How many users experience this behaviour?
AMD support seems to have recognized the issue and reported to their engineers.
Hardware info:
Monitor xg2401, tried 2 different displayport cable
Vega 64 strix, tried various bioses and drivers, now 19.6.3
CPU Ryzen 2700x
Motherboard Asus CH7 WIFI x470
Windows 10 1903 x64, 1803/1809 show the same behaviour
