It does not work well when applying ray tracing with vr using oculus rift.

When you play the vr of UE4 with oculus rift, the screen where real-time ray tracing is applied normally appears only for the left eye. However, the right eye looks like you turned off Deferred Lighting. Different screens appear on the left and right respectively.
Is there a good solution?

It is the performance of the PC you are using.
