GoW Kratos Shadow DX11?

You should disable the "Large Framebuffer" option as can decrease performance.

Also, the MTVU speedhack should be enabled unless the game is reported to have problems with it.

Hmm i wouldn't have though a Haswell 4770K CPU at 4GHZ and GTX 1070 would be a bottleneck for this emulator though?

Some parts of GSdx can be optimized. However some parts aren't compatible with fixed function unit of your GPU.

For example, the blending accuracy setting replaces the optimized ROP of your GPU by a slow emulated-on-shader equivalent.

I think you should try to disable the large FB option. Hopefully it should reduce a bit the load on your GPU.
