Rogue Epic Glow Problem

[Akura]

I just got my Ragebringer and initially I didn't see any glow, I played with virtually every display setting and somehow it started glowing blue at night. It looked fantastic however adversely I started lagging in combat and went back and played with the settings and figured out it was the shadows that was causing my problem but now I lost the glow on my epic and no matter what I adjust in display tab I can not get it back. I also logged in my new gaming pc and I have no glow on that computer either. Any help would be greatly appreciated. I would love to enjoy the visual benefit of my epic.
