Ninja Gaiden Sigma slow motion problem

My SPEC: CPU:i7 6700K, GPU:GTX970, RAM:ddr4-16GB
RPCS3: v0.0.5-6605-2c16dddd
Gpu render: vulkan

I have a problem when i was playing Ninja Gaiden sigma , everthing act like slow motion.
The cpu utilization is only 15-20% , and the game shows like 29-30fps, never up to 40 or 60 fps.

besides，the performance of other games (like demon's souls ) is fine , and the cpu utilization go up to 60-70%.
It's really really strange...I have try different version of rpcs3 and different version of the game，but the slow motion problem is still the same.
I asked other players in china ，looks like i am the only one who meets this issue. It's really borther me
