Enable Video BIOS Shadow Caching
Shadowing the video BIOS (on the video card) is a performance enhancement that you can enable for a small performance increase. In addition to shadowing the video BIOS, you can also enable caching of the shadowed BIOS for a further (small) performance increase. This is controlled with this BIOS setting.
Note: It is not uncommon for
problems to be encountered when enabling video BIOS shadowing, as explained here, however,
if shadowing works, caching the shadowed video BIOS should normally work as well.
