Yes I sure have. here is my Dxdiag. DxDiag.txt (84.3 KB)
Whoever made the decision that Budgeting should be put into a separate Component needs to be fired, like seriously.
From the DxDiag it seems you got 2 monitors connected to the card right? Try to disconnect one.
How much power your power supply can handle? A model would be nice to have to check its certification.
1000 watt power supply. I built the system myself.
The power supply is more than enough, but the graphics card also receives power from the motherboard’s PCIe x 16 slot, which might be the culprit if some power phase is actually bad in the motherboard.
There is a known issue which happens with several graphics card models against certain motherboards which makes the graphics card to disconnect. This affects several 3D applications and games aswel. This would happen with the editor switched to Dx12 or Dx11 no matter, so I guess this is a bad luck. The possible choices are not many, it would be interesting to know which are the graphics card and motherboard brands, and if you could borrow someone’s else motherboard and see if the issue somehow stops happening. An alternative is to check if your motherboard BIOS has received any update that could improve this, but I recommend leaving the update under capable hands because an error might leave your system unusable along with its data.
If you search on google by " D3D device being lost" you will find several reports on the engine and other applications like Substance Designer/Painter, and lots of games, some based on Unreal and others not.

Soo I noticed that in the FCollisionQueryParams, bTraceAsyncScene is missing? Has this been replaced with a new boolean?
Not just that but the ‘Digital Human’ project, both face and hair looks better and softer in 4.20 than in 4.21.
Is there a way to set the Class Default parameters in the Editor Utility Widget? Would be great to be able to make changes and than when loading the widget again having those values saved to the asset.
We’d appreciate more information regarding how the Datasmith plugin is not working for you on Preview 6. Please report Datasmith issues at this link.
@Bladerskb Yeah, the screen space irradiance PPM is also broken since 4.21.
Async scene was removed
I just posted a fix for that here: https://forums.unrealengine.com/development-discussion/rendering/1576306-screen-space-irradiance-not-working-in-4-21?p=1598994#post1598994
Is it possible to submit a pull request for the sample projects?
It’s working now, thanks witch-dev!
This solves the face issue but it doesn’t solve the hair issue
Before more people jump on this bandwagon and (unjustly) brandish their pitchforks - The mesh component inside ACharacter is created using CreateOptionalDefaultSubobject which means that you can change its class like this:
AMyCharacter::AMyCharacter(const class FObjectInitializer& OI) : Super(OI.SetDefaultSubobjectClass<USkeletalMeshComponentBudgeted>(ACharacter::MeshComponentName))
{
//...
}
With this you don’t have to add another mesh component to your character, and all the old code still works, you just make the default mesh a different class. It’s actually win-win-win - old code works, the default mesh component hasn’t introduced additional bloat and checks and it’s easy to swap in and out as needed.
Epic just uploaded an excellent talk/walkthrough from GDC presented by Sjoerd De Jong covering raytracing features and implementation:

Somewhere I saw this, but its follow me from 5th preview. Earlier I uninstall and then install again UE4. Now I’m to sly to do this again. Should be solution.
Not working this rebuilding.
