So in GTA 5, Freesync only doesn't work; I get screen tearing. I have a 75 Hz Freesync monitor.
Now, if I enable Vsync, no more screen tearing occurs. If I disable freesync from Radeon Settings, the game caps at 60 FPS. If I do enable it back again and set the ingame refresh rate to 75 Hz, game runs nice at 75 FPS. Does that make sense? Is Freesync kicking in at 75 FPS?
