I have a Nvidia GTX 960. I looked up how to switch it to high performance, and it looks like I’m missing the option or something.
Anyway, I found something else that’s probably causing it. There’s this little window that opens at about the time time interval as the Mirage minimizing thing. It’s only appears for a split second, so I’m trying to catch a glimpse of what it’s called. I’ll get back when i figure out what it is.
(I’ve read that it’s Microsoft something so far)
