Hello, any help would be appreciated.
I have seen a few people with this problem but no solution yet. I am currently using the acer xr34ck for my monitor with an r9 290x's in crossfire, running windows 10 with the november update.
Recently I updated the driver from 15.11 to 16.1, freesync worked on 15.11, but after the update, crimson shows that the monitor does not support freesync. I used DDU and reinstalled 15.11, and freesync works perfectly.
