Big known performance issues at the minute mate.
& yes it does perform pretty crappy on a 970.
Somewhere between medium & high I'm hitting 45fps average.
Msaa takes a massive toll & pushes vram usage up to 5gb.
Disable it, use fxaa instead - it does look worse at times but pushes another 10-15fps & lowers vram usage considerably.
The popin of trees etc is a constant - no such issue on the Xbox one version.
Think this maybe down to Microsoft's enforced DRM which does 256bit decryption on the fly.
Pushes heavy disk & CPU usage on the primary core.
The Xbox one version performs & looks better IMO which is somewhat of a first.
There's a survey here that a lot of people have took part in showing performance on different system configs.
