What I find odd is the TSR has ghosting problems no matter what version or setting I used. Objects that move leave a smear on the background, or when you move the camera the objects closest to the viewport smear on the background. And when you rotate an object , the background smears on the object for at least 1.5 seconds.
5.1’s cinematic TSR has been the only way to reduce the ghosting vaseline smear on backgrounds to an acceptable standard for my game. But the rotation smear bug has still not fixed and cinematic TSR also eats 4.56ms on 1080p 
I suggest making a post in the feedback section of Unreal. TSR is better than DLSS and DLAA in terms of not leaving serious colored ghosting on further objects when the camera moves.
