Nope it appears they did not : ( 21.5.2 full install on Windows 7 fails to provide a FRTC slider. Trying chill or any other frame rate limiter in conjunction with Enhanced sync results in unacceptable stutter on my 60 Hz display. Back to 20.4.2 with Radeon Settings then. Very disappointing - this whole FRTC saga reeks of incompetence or forced obsolescence - outside of this i cannot understand why one would pull a perfectly good feature and leave your customer to choose between tearing, stutter or older drivers in the midst of a GPU shortage. I hope AMD learns a lesson... in effect the last good driver was 1 year earlier than the last official one. Glad i wasn't a 300 series or Fury customer.
