Intel Hd Graphics Draiver Skachat
So actually you have two issues, the intel integrated graphics driver needs to be updated in order to run the current version of the engine, but more troublesome is that the engine is not using the Raedon Graphics card that your DXDIAG is listing. Check in your Catalyst Control Panel and ensure that Unreal Engine is set to use the Radeon card and not the Integrated graphics card. This should also correct your crashing issue.
