Hi Guys.
Like the title says, i dont know why i only can get 10fps in a lumia 640 an more than 50fps in Lumia 50fps.
I have downloaded another games from Store, and the problem its in my game only.
Anyone got this issue using Unity?

Fixed:
Its because i have in Player Settings → Other Settings → Vertex Compression V1 checked.
I dont know why this steals all my fps, and do it on Lumia 640 but not in 535.
