Re: Significant fps drop gtx1080
What are the rest of your PC specs? (CPU, RAM, etc). Also, what graphics settings are you using? Ultra, High, Med, Low, Custom? There are some slight changes you can make that make a world of difference on your FPS.
Also, since playing last week to playing now, was there an update? Sometimes updates will effect FPS in-game. Sometimes it is something in the update that screwed things up and you will have to deal with it until they fix it. Another thing I've had happen in other games is that either an update, or for no reason at all, some of my graphics settings changed and ruined my FPS. Double check your graphics settings and make sure EVERYTHING is EXACTLY the same as it was last week. Like above, a single graphics setting can drastically effect your FPS.
