I just upgraded to a Sapphire RX 580 card. I followed some online tutorials and tweaked some settings (mild undervolt and overclock, nothing extreme), and was running Overwatch on High settings, plus a couple more bumped up, smooth as butter. Then I got ambitious and set up a second monitor, connected to the card HDMI port. My FPS instantly crashed down to the 30s and 20s when things got hectic in game. I saw a post that suggested enabling GPU scaling on the second monitor. I tried that, but no better. I disconnected the second monitor, and things were still awful. I ended up going into the registry, based on a Microsoft support article, and deleting the extra monitor keys. That helped a lot, but I'm still seeing some hits in-game when there's a lot of action, even though I have the settings lower now than I did before. Can someone suggest what I need to do to get back to where I was? Do I need to do a factory reset?
Thanks in advance.
