Generally, you want the GPU to be primarily concerned with rendering.

If you need occlusion culling for a detailed scene being rendered, it's recommended that you enable Support Software Occlusion Culling in Engine > Rendering.Scroll to the Engine section, select Rendering, expand the Culling section, and uncheck Occlusion Culling.If your game does not use fog, we recommend disabling Vertex Fogging to increase shading performance. Vertex fogging applies fog calculations at each vertex in a polygon and then interpolates the results across the face of the polygon.D3D12 should provide rendering performance improvements besides avoiding the additional render pass. Selecting D3D11 will have a negative performance impact due to the platform performing an additional render pass.Ensure Default or D3D12 is the selected Default RHI:.Scroll to the Engine section, select Rendering, expand the VR section, and enable both Instanced Stereo and Mobile Multi-View.You can find more information in Unreal's documentation.Forward Renderer is much better for Mixed Reality than the default Deferred rendering pipeline because of the number of features that can be individually turned off.Scroll to the Project section, select Target Hardware, and set the target platform to Mobile/Tablet.You can find each of the following settings in Edit > Project Settings.
You're encouraged to read up on application bottlenecks, analyzing and profiling mixed reality apps, and general performance fixes before continuing. Unreal Engine has several features that can increase an apps performance, all based on the discussion outlined in performance recommendations for mixed reality.
