HP Recommended
HP ZBook Firefly 15.6 inch G8 Mobile Workstation PC (1G3U9AV)
Microsoft Windows 11

 

I transitioned to a new laptop:

HP Zbook Firefly 15 G8 

32GB RAM

Windows 11

Driver  Iris Xe  5/13/2022 30.0.101.1994

 

I have a parallel posting on Intel Iris site

 

Question:

1) Why is the setting in UEFI for VRAM not properly reflecting in driver of Windows 11 

2) What / where can I set registry key to enable DirectX (dxdiag) to report more then 128MB of video RAM so programs which still use this can work correctly
