Nvidia Re-Size Bar/SAM support is live for some cards, more in March - 10% performance gains

[scubes]

Is there any performance increase?not touching me PC new feature or not .

 

[Evilpaul]

Just updated the vBIOS and installed the latest drivers on my 3060 Ti without any problems.

A quick run of the Borderlands 3 benchmark (DX12, Badass quality, motion blur off) went from 77.71 FPS to 84.53 FPS, can't complain about an 8.8% increase.



edit -

Found an old benchmark score (Ultra High) from AC:Valhalla: 68FPS to 72FPS, which is 5.9% increase.

@ltron Ta I’ll have a look this eve

 

[Steve Hel]

Only tested in Metro Exodus and seeing some nice gains.

Here are my own benchmarks with ryzen 2700x and rtx 3070

Cyberpunk 2077 benchmarks

Witout RBAR

Valhalla Benchmarks

Without RBAR
1080p Ultra = 81
1440p Ultra = 66

With RBAR
1080p Ultra = 86 (%6.1)
1440p Ultra = 69 (%4.5)

Spoiler: valhalla benchs

1440p no rbar

1080p rbar

have to say, cyberpunk felt somewhat snappier than before. %1 and %0.1 lows were also a lot tighter and closer to average fps. but i bet improvements would be overall higher with a 5000 series cpu

I wont be rushing after checking the games supported, I dont own or play any of the tiny list of games they have enabled, waiting for support for jrpg's etc. They seem to be prioritising AAA titles.

 

[Dontrocktheboat]

Some decent increases across the board.

Good to see.

+
upgrade was easy as pie, quick bios update, new drivers bish bash bosh done.

Good job nvidia.

Neither will i, even when i get a 30 series, as looks like the resize, works best at 1080p, im at 3440x1440, so can live with out the extra frame, or the 2 extra ones (judging by the above 1440p results with the bar)

 

[Nexus18]

Well it works on my b450 tomahawk with my 2600 (3080 FE)

Great improvement in cyberpunk @3440x1440, staying more often at 50+ fps now in the really busy areas (max settings and ray tracing on with dlss set to quality) and not dropping to high 30s/low 40s anywhere as much in those CPU intensive areas. Even outside the intensive areas where FPS is about 70+, it's improved.

Ran the BIOS update as it said it was supported. Ran it, reboot and system information shows Resizable Bar: No

Any thoughts?

Make sure booting from GPT, and CSM is disabled.

 

[opethdisciple]

Update the drivers first then install the vbios update?

Can you explain what this means? Sorry those things don't mean anything to me.

I'm waiting too until the bugs have been ironed out as my system is rock solid stable now. Some BIOS versions for my Gigabyte X570 Master have been finicky with my 3600MHz RAM too.

I think I'll wait for final versions using AGESA 1.2.0.2 which will probably come in a couple of months, 1.2.0.1 patch A is still only in beta BIOSes.

I am very interested to see the performance results though and how it compares to AMD's SAM.

The gptgen (method 3 in the beebom link) looks the most promising in my opinion.

You have to enable it in the bios too.

 

[tommybhoy]

Anyone using Palit got the rebar bios update yet?

 

[LiE]

You have to enable it in the bios too.

OK so I can see that my disk is using GPT. I have found the setting in the BIOS to change from UEFI to CSM. Why do we need to change to an older version of the BIOS interface to use this? Seems a bit of a BIOS gimp.

 

[ltron]

You need to enable Above 4G Decoding and Resizeable Bar in the BIOS and disable CSM in the BIOS (a compatibility mode for older hardware). Just be aware that disabling CSM will render your system unbootable if your Windows was installed using the old partitioning method called MBR.

You've got to disable CSM not enable it. It's good that your disk is using GPT.

If CSM is already disabled then that is not the issue.
