This is a BIG driver release for Nvidia.

All Geforce RTX 30 series graphics card can now support Resizable BAR, though this hardware feature will require firmware updates for most RTX 30 series graphics cards to function.

What does this mean? That the driver will activate it or that an GPU needs like an BIOS update?...

It's exactly what it says.

You need to flash the BIOS supplied by the AIBs. I did my gaming x trio 3080 this morning, takes like 6 seconds.

It's really just exactly what it says.

The driver will enable the feature. The BIOS is required to be updated to provide the feature so the driver can use the feature.

While you often can flash with other vendors' BIOS, like people do for higher power limit or to enable RGB support for Founders' Edition cards, in this case there's an universal tool for the entire 30 series: https://nvidia.custhelp.com/app/answ...re-update-tool

Though using the partner version (links lower down that page) is probably preferred. Not sure if the universal tool preserves factory OC - universal BIOS at least doesn't, but the tool might just edit the VBIOS in place.

Flashing your GPUs BIOS? That sounds scary, since the high risk of bricking your expensive and very difficult to get graphics card.

Not as bad as you might think, since a functional GPU isn't required for successful booting and if the process fails you can retry, as long as you don't reboot. You can also back up the current vbios with nvflash, so restoring that is also a possibility.

Though recovery process is more cumbersome if you reboot and don't have a machine with iGPU/second card handy.

A driver is not firmware, It is software.

Both the motherboard and the GPU have to be updated to the latest firmware, After that comes the GPU driver.

Come on dude it's really not difficult to understand, You aren't new to PC's
