4.4.1 Preview doesn't start on dGPU in Rift direct Mode

Laptop with intel HD 4000 and nvidia GTX 880m (Optimus):
Unreal Engine runs totally fine in Oculus Rift extended Mode. But setting up Rift mode to direct mode and starting up the engine leads to the message “DX11 feature level 10.0 is required to run the engine”. When run in direct mode on the internal GPU it starts up. So this only applies to direct mode on the dedicated GPU.

This still applies to the released 4.4.1 hotfix. Direct mode works totally fine on my desktop computer, but still has issues on my Laptop. This is an issue of the engine as direct mode works fine with the demo scene of the configuration utility.

Hi ,

That message has been seen before with UE4 and the previous known solutions was to download the platform update for Windows located here:

Please let me know if that helps.
