Resizeable bar support? Nvidia also has it as of today

Intel 10th/11th gen. chips only

FYI Resizable BAR is also available for Intel 8th & 9th gen CPUs on the Z370/Z390 platforms, if your motherboard manufacturer is generous enough to provide a BIOS update for an old product.

Luckily enough Gigabyte is one of them, and I got it working with a Z370 Aorus Gaming 7 and 9900k.

Mines an Aorus Z390 I think. I’ll have to have a look.

ASUS Strix Z390 F Gaming is ok as well

Wish we could get someone from MS/Asobo to answer this. More and more of us now have resizeable bar enabled and for most of the big, modern games it increases FPS by 7-10%.

Just enabled mine - have an Asus ROG Maximus Xi Hero WiFi and finally just updated my BIOS which was my last step and it’s enabled!

It’s good for some games but Flight Simulator isn’t supported.

I have a Gigabyte RTX 3080 Gaming OC and Intel I9-10900X running on AORUS Master X299X, just updated GPU and Motherboard with new BIOS to enable rBAR.

I could not beleive it, but I have some +10FPS in MSFS now, so it seems that rBAR has a massive effect on performance within Flight Simulator.

Before I had always issues with “limited by main thread” keeping frame rates low.
After activating rBAR this is nearly gone.

I get about 40 up to 72 FPS with Ultra Settings now in 4K resolution, before I had about 28 to 59 only

resizeable bar has to be enabled in the nvidia driver per each application (mfs) . just because the vbios and mb bios and the generic nvidia driver are all r-bar = yes doesn’t mean r-bar is activated–driver for mfs has to enable r-bar for it to work.

there are ways to set the bits in the nv profile to enable mfs app to run with r-bar, do a google search on ‘resizeable bar nvinspector dcs’ and it will show the 3 ‘unknown’ config addresses tweaked to enable r-bar in mfs.

but actually no one knows for certain r-bar is working, no proof as there’s no hw indicator that tell you it’s running, at least for now.

i tried setting the 3 config addresses for mfs and it seemed like it’s running smoother, but it was pretty smooth to start with so can’t say for sure r-bar is working or it has an impact…

time will tell.

Hey I have a similar setup i9 11900K and Asus Tuf 3090 OC. I’m certainly not complaining about poor performance. Still I’d like to update the bios. Never done it before. Did you use the bios flashback feature? and for the GPU I guess I just download it and install? Any tips would be appreciated.

Hello, I have used the files directly downloaded from Gigabyte support pages, worked perfect to update the BIOS of GPU and Mainboard. I have no experience with Asus GPU cards, but should work the same way. For GPU I could use the executable provided by Figabye.
For Mainboard I did use the @BIOS Tool from Gigabyte APP Center.
