Playing Crackdown 3 on PC with 2080TI and PG27UQ which looks great, but I am experiencing a strange issue. During the game, anytime an Xbox achievement pops up or other message displays on the screen, the monitor goes black for a few seconds and then comes back up. When the achievement window or message disappears, it again goes black for a few seconds and then comes back up. If you disable HDR in Windows and in the game settings, this doesn't happen.
Anyone with a similar issue?
