I downloaded the 8KX 90hz beta, updated with DFU.exe. And reinstalled outdated Nvidia driver.
But oh! I forgot…
Last week I obtained the latest VGA Bios for my ZOTAC 3090, updated Nvidia Driver and activated resizable BAR feature for my 570 Mainboard with 5950X
If You look at Nvidia homepage to activate Resizable BAR there is a precondition.
Update to the latest GeForce Game Ready Driver (version 465.89 WHQL at the time of writing, released March 30th, 2021), or a later version
So I can either select Resizable Bar or 8KX 90Hz, but, of course, I think we need both activated.
Could You help us out there?
