Ive been getting some pretty bad stuttering in games when i have raptr running (mainly battlefield 4 and Hardline)
It only occurs when i have raptr open. They both run fine when it's closed
I've noticed this as well with multiple other games, the issue goes away when I disable the ingame overlay (which for some reason has also been getting stuck up when the issue has been happening)
Just as a note, I hadn't notice this issue start until GVR was introduced. I have it disabled already, before someone tells me to do that.
