Frames dropping hard then coming back

Before the current patch I was playing at a constant 60 fps. Now during this current patch I’ll drop from 60 down to 20 or 30 then after 2 or 3 minutes of playing it will go back up 60. None of the setting have changed. This was an issue back in season 4 or 5 but after returning a few weeks ago I haven’t had this issue until the current patch.

Are you using any Razer devices?
