Horrid Bios version - 1903 & rollback

[TheNower]

Hi guys, 

Not sure if anyone has experienced this but I recently updated my bios to latest version (1904) and now has caused horrible CPU stutter in games. So so frustrating. 

CPU: intel i9

Board: Rog Z590 hero XIII Maximus

Bios version: 1903

Usual drivers are up to date

Could someone advise how/where I go to grab previous/older bios versions?

Thank you

Now unable to roll back to older bios - says bios isn't recognised/supported via EZ Flash utility. What a nightmare.

perhaps! I rolled back 1903 to 1801
I also changed the bios firmware of the Rog Z590 Hero XIII Maximus to 1903 and as a result ... I had to roll back to 1801, just flashed straight from the bios

возможно! я откатил 1903 на 1801
Я то же поменял прошивку биоса Rog Z590 Hero XIII Maximus на 1903 и в итоге ... пришлось откатить на 1801, только прошивал прям из биоса
