Over the past 2 days I've read pretty much every single article written about the Origin launcher making people's games basically completely unplayable. Basically the games will stay minimized in the taskbar if you try to go fullscreen. And even in windowed or borderless modes the game will sometime lose focus and you'll lose control of your mouse and keyboard for a couple of seconds. Well after many hours of tinkering I *may* have found the root of the problem. (asterisk because I just bought Battlefront II on steam yesterday, so that's the only game I've encountered the problem with, but reading about other games with this issue it seems like the same exact root cause).
ANYWAY:
It's because the Origin Launcher is trying to run at a slightly different frame rate from your game.
Here's all you have to do:
For all other games with the same issues described:
Hopefully this guide helps a couple people out.
EDIT: Nevermind. That didn't work. Go to your gpu control panel and change scaling from 'maintain aspect ratio' to 'centered'. I then went to the intel control panel (i'm using a laptop with hybrid graphics) made sure just to go over to to system - power, and changed the power plan to maximum performance, turned panel self refresh and adaptive brightness were both turned off.
Everything seems to be working at the moment.
