Packaging--> Performance issues

[BernhardRieder]

After packaging the game the performance is much lower than in the actual game play inside the editor.
What do I have to consider when packaging to keep the same performance?


ps: packing for shipping is totally broken when using Ray Tracing - Reflections and Shadows are broken --> that must be a bug.

Hello,
Which version of the engine are you using?
Do you have the same issue: bad performance and broken reflection/shadows when packaging in development?
How did you enabled the dx12 inside your UE4 project, did you add the -dx12 in the command line of your UE4Editor or did you turn it up in the project settings?

I am using the latest release.

Bad performance is on both packaging for shipping and development.
Broken reflections & shadows do appear in the Shipping Packaging only.

@DX12:

• The Ray Tracing is turned on inside of the project settings
• The Unreal Editor will be launched with the proper command extension -dx12
• The Game will be also launched adding the command line -dx12

I considered every possibility and kept running tests with other projects and different computers.

It looks like it's a bug you should be able to re-create yourself very easy.
