Says it all in the title. I've had people who have watched my gameplay have said, "WTF kind of reg is that?" as well. Pretty sure it's not just an issue with me.
Hit reg is atrocious
I hear a lot of people saying hit reg, a lot saying TTK. Do you have any videos of your issues? I'm seeing something similar which I can't quite identify, so I'll grab some clips to show what's happening.
