In our testing, we've found some titles benefit from a few percent, up to 10%. However, there are also titles that see a decrease in performance, so NVIDIA will be pre-testing titles and using game profiles to enable Resizable BAR only in games where it has a positive performance impact
this absolutely has to be done by nvidia,users can't be left to do the testing themselves as you lose performance almost as often as you gain some [SPOILER="SAM"] https://static.techspot.com/articles-info/2178/bench/1080p.png[/SPOILER] from amd's SAM review
Now, because this isn’t a feature you can simply toggle on or off between games as it requires a full system reboot, you’re either going to game with SAM enabled or disabled.
this is not the way to do this. I don't want a feature I have to test myself for every game

needs a vbios update from manufacturer

So. A VBIOS update from the manufacturer.... What would this mean for the people running "non stock" BIOS's? I have the kingpin on my FTW3 ULTRA 3090.

And here's to hoping they bring support to tRX40 chipsets.

"A vbios update from whoever provider your current vbios" I guess, to make it generic enough to fit your particular situation. (For the vast majority that is the same as "a vbios update from the manufacturer", obviously)

I'm struggling to see the problem, get the Kingpin bios with the update.

AMD warum kein X370 support. Total unverständlich!

Interesting. So if I'm reading this right we need bios updates for GPU and MOBO and also a driver that supports a feature that's been lying dormant for over a decade, but they are unable to enable or disable it at a software or hardware level without a system reboot? Maybe if we buy an additional 100$ USB dongle with some random code on it that always sits in a USB 3.2 drive they can enable/disable it on the fly? 😀
i think they are able to do that. i dont mind a system reboot but i don't understand how amd wants the user to do the testing themselves. lazy !!!

Let's be realistic here , most of us when we get this feature we will enable it and leave it on 😛 especially if we hit the target frame rate.... I know i would !

Have they stated what CPUs it'll support? I assume they'd not artificially limit which Intel CPUs are supported but they might pull an AMD and artificially limit it not to include AMD.

I do not think that was ever a consideration , nvidia does not have a x86 cpu in the market by limiting to Intel only they will make their GPUs a little bit slower on that specific ventor , i do not think nvidia loves intel more than amd or the reverse 😛

I haven't seen any list of what nVidia are going to support. Last I heard AMD won't support anything but Zen 3. People were quick to white knight for AMD claiming it's a compatibility issue and it's not possible with earlier chips. We quickly found out that's bullshit.

I was quick to say that this is bullshit and they should allow it on all the ryzen cpus, i mean it is a pci express 3.0 feature so there is no special sauce on the hardware side .

Right. Was mostly asking if there were a particular risk to us on an obviously different BIOS. Being it could brick it maybe. Hardware ID and BIOS not matching up? Maybe it just allowing it altogether until one slaps a stock VBIOS on? Not sure about what the the confusion was between the two who commented.....

It is also possible that Nvidia will put out a generic vbios update like this one for the GTX 1080 and below for Displayport, NVIDIA Graphics Firmware Update Tool for DisplayPort 1.3 and 1.4 Displays

I bet it works with Zen 2 as long as your motherboard supports it. They just dont claim "support" for Zen 2, but it will still work like on AMD side.
