I've seen this new vbios version (v4) launched in april 30th, with the same description than the previous one.
Does anyone know if this upgrade is necessary or what's new?
Thanks

NVIDIA Resizable BAR on systems with an ASUS GeForce RTX™ 30 series graphics card
NVIDIA Resizable BAR technology gives a system’s CPU direct access to the entire GPU frame buffer. Multiple CPU to GPU transfers can be made concurrently instead of being queued, leading to a performance boost for memory-intensive games and workloads.

To enable Resizable BAR, please ensure your system meets the following minimum requirements:
1、Intel 10th Gen or AMD Zen 3 CPU
2、ASUS motherboard BIOS is updated to support Resizable BAR
3、System uses the latest NVIDIA VGA drivers

Looking for info on this as well. The update notice reads exactly like Version 3 bios. Need to know if there is any reason to update it. I wish they would be more descriptive when publishing updates like this.

Ok i tried to upgrade my 3090 Strix with v4 now, it already had v3 installed and rebar working. So the installer just said i don't need to update my card.

So i guess it must be some hardware variations that didn't get updated with v3 this is for.
