I have a NUC8i3BEK. After updating the BIOS to version 071, gaming performance dropped by half.
I think the reason for this is the Removed option for 2048MB on IGD Aperture Size setting.
How do I downgrade the BIOS version. I tried almost all the ways to downgrade. As I understand it is now impossible to lower the BIOS version.
Maybe a BIOS version will be released in which this option will be returned?
Thanks for the answer.
Earlier, I had already updated the BIOS to version 071 via the power button. Nothing has changed.
When I try to downgrade, I see a message - incompatible BIOS Version. As I understand it, if I updated ME firmware I cannot downgrade the BIOS.
Can the jumper method help me?
I would add that THIS HAS ABSOLUTELY NOTHING TO DO WITH THE BIOS SETTINGS! The settings in the BIOS are completely ignored by the Windows Intel HD Graphics driver. The Windows HD Graphics driver dynamically manages, based upon application requirements, the amount of memory assigned to graphics operations. Up to 50% of the available memory may be used for graphics operations, if needs require.
The likely reason why you are seeing a slowing in the latest BIOS is because of the mitigation added for some of the new (ala Spectre) side-band attack vectors that have been identified.
