I have problem with freesync since Crimson 17.2.1 install. (MSI R9 290X + Acer XF270HU)
In fact, the FPS are very unstable since this install and cause flickering display with games (FIFA 17, Battlefield 1...). I don't have this problem with driver 16.12.2 and if i disable freesync, it works without problem.
So the problem is really causing by freesync.
Thanks for your response
