Its surprising that noone has reviewed this monitor properly yet but here are my tips:
Keep overdrive at step 3, that is default. Any higher and you will get overshoots, like motion trails on edges.
Remember to set overclocking to 170Hz. Use gamevisual Racing for anything since it is pre-calibrated. For FPS games you can use FPS profile for boost in colors but i think its too much. Racing is really nice.
Enable G-Sync Compatible and dont use ELMB-Sync as it seem to make motion clarity even worse by using it.
