    The performance penalty is game dependent. For me the fps in Witcher 3 doubled (~50 to ~110) after disabling the option while for BL3 it was only an increase of around 10-15fps in total. See bug 1039
    Thank you for the link.
    Let's hope that such problems get sorted out with bios updates.

    • So, with UEFI boot the extended BAR seems to work on my system. (The "above 4G" BIOS entry is set to enabled. No extra "extended BAR" option in the BIOS)

      • So does this mean the latency of GPU<->SSD that everyone was saying is the best on the Sony PS5 can be matched / beaten right now on the desktop? Or am I confusing technologies?
