Low FPS on Overwatch only

I’ve been getting 35 fps or lower on Overwatch after the update. I have tried lowering my graphic settings, but it will barely go above 30fps. I DON’T have my fps capped at 30 fps, so that isn’t the issue. Everytime I die, it goes back to normal fps, but then goes back down when I respawn. Any ways to fix this?

Hey, Spyfish! With the Razer Cynosa Chroma, I’d suspect the Razer Chroma low FPS issue is the cause. Toggling the Overwatch Chroma Profile, on and off, and if it continues, performing the steps on this post should address this concern.

The behavior we see with this is the spectator mode and menu are normal frame rates, but while in-game the FPS drops to anywhere from 10-30FPS.

Thank you so much, this really helped me!

I hope you have a nice day!
