I have the Intel Core i5-1035G4 CPU with the Integrated Intel Iris Plus Graphics. Using the DirectX Diagnostic tool under system I was able to see that I have the supported version DirectX 12 however under display the DirectX 12 Ultimate is disabled but this is not mentioned to be needed for vibrant visuals. My device should be compatible with the Vibrant Visuals however when I login it is greyed out and I am unable to select an option. Would love to know how to get it working. Is Minecraft not correctly detecting my integrated graphics?
Minecraft requires Intel graphics drivers version 31.0.101.3430 or above to run on DirectX 12. The latest graphics driver version for your processor is 31.0.101.2135, so unfortunately you will not be able to use Vibrant Visuals.
