My advice is not bad. VRR just matches the frame rate of the game to avoid judder VRR can go to 40fps on Xox series X frame doubling does nothing you trick the screen into thinking there are more frames called lfc every frame stops for two I don't want to play at 20fps. vrr does nothing on locked frame rate I choose locked 60fps V Sync avoids screen tearing I have xbox on 60fps GENERAL vrr off I play in atta frame mode but for game mode. with 4K locked 60fps gaming with TruMortion on de-blur which is for 60fps and reduces blur in fast motion looks smoother and feels like 120fps I don't notice any input lag. If input lag is a problem play at 500fps on a 500hz screen
