What are the settings at?
1920x1080p.
Normal.
SSAA Off.
Texture Filtering AF x16.
Tessellation off.
V Sync off.
Advanced Physx off.
Try turning the texture filtering down. That can affect performance.
Come to think of it... Try updating your drivers to the newest beta driver. I had massive suttering in another game, but 60 fps like in your case. If you're using GeForce Experience go through the settings, and find the option for it to update to beta drivers.
Hope that helps :^)
