Features »» Dynamic Frame rate Control (DFC)

Dynamic Frame rate Control feature or DFC allows for real time control of maximum rendered frames displayed per second. DFC is aimed at providing smoother gameplay by limiting the maximum displayed frames per second for games whose frame latency vary too much, for example, if a game is keeping frame rate between 50 and 80 FPS, you can set a limit of 45 FPS and enjoy a smoother experience thanks to more stable frame latency. Even if the game is capable to deliver 60 FPS, DFC set to 60 FPS as target can also help by smoothing the frame latency, try titles like Assassin’s Creed Brotherhood or The Elder Scrolls V: Skyrim, the stuttering seem on those games with plain V-sync is removed by using DFC + V-sync on.

The target frame rate can be changed in real time without leaving your game. Just press the hotkeys assigned to DFC control, by default the keys are CONTROL+Insert to increase target and CONTROL+Delete to decrease target.

DFC doesn’t remove screen tearing so if you want to avoid tearing, either turn V-sync always on in RadeonPro Tweaks tab or use your in-game v-sync option.

Like DVC, DFC can also be turned on and off with the press of a key.
