Ue5.1 Issues with GPU lightmass

I can report that the current latest Nvidia Driver version 528.49 (tested game ready version, others have said the studio driver works) seems to work fine.

Using 522.25 may now be outdated advice.

EDIT: - per Luoshuang’s recent post. 522.25 is still the recommended driver to use for now because 528.49 still has some problems with certain feature sets.
Although he did mention that Nvidia is aware of the problem and a fix is due to come at some point - His post Epic's GPUlightmass - #445 by Luoshuang

I will keep my posts updated.
