I think a lot of this comes down to your setup.  I&#x27;ve been messing around in Unreal Engine with DK2 and don&#x27;t have those issues because I&#x27;m not using a laptop with Optimus.  Now, granted, I also have a laptop and it does use Optimus so I&#x27;d love for a fix so I could use that laptop as a mobile demo setup but either way, I think it&#x27;s just a matter of the current implementation requiring you to use supported hardware in order to develop for it or just use it.
