All the effects I think. I can play about 10 matches and I get painful eye aches/headaches. It’s the constant flashing. I get the menus and everything, but every time you guys “improve” the battle screen you make it worse. I do my GW fights, dungeons and daily tasks now and that’s it. If it’s not fixed very soon…like in a day or so then I’m done. That’s not a threat, I just physically cannot keep playing. I know several people are having the same issues.
