I guess the whole "fine wine" meme continues on. Looking forward to trying this out. Hopefully I won't need any VGA BIOS updates.

It's nice that you can enable it from driver level now , not from BIOS 🙂
Kaarme
Considering I can't buy a new video card without paying scalper prices in the current situation, likely to continue into the foreseeable future, I'll just keep waiting for AMD to enable smart access memory for my museum card.
AlmondMan
You still have to enable it in BIOS? If you had a 5000 series card before, you could enable it, but gain no benefit. Don't see a note in the drivers saying they enabled enabling a BIOS level feature through this.
kapu
After last update i have option in drivers to enable or disable smart memory .
Not sure what happens if its disabled in BIOS .
Anyway it's good that you can now clearly see its ON or OFF.

It has to be enabled in BIOS for it to appear and work in Windows.

Okay and now why can't Nvidia do the same with Turing cards? That VBIOS requirement just seems a bogus to me, since RX 5000 doesn't need it either.

On the patch note of this driver they said it work ONLY with chipset serie 500...
I confirm that it work with B450 (and so X470 i think) the same way with Zen3 CPU.
Volteron
Yea it's embarrassing for Nvidia, this should of been done for us to, I guess that's what you get for paying premium.
rl66
You have to disable CSM on some board (B450 for me), in CPU you should found something "above 4G decoding" enable it, and then found something like "enable Resizable BAR" (the real name of it) and enable it too, save the change and enjoy.
cryohellinc
Because that's Nvidia for you - everything they will do is to limit the user down to only their ecosystem and then further segment it. They always want to create an obstacle for their own use that will force them to upgrade to newer hardware.
AMD (at least for now) doesn't do that, hence why they will get my money for the next generation.

Too bad nVidia has already abandoned Turing...
Kaarme
They are possibly re-releasing 2060 as a brand new card (with more memory). That's the opposite of abandoning it.
Horus-Anhur
We are talking about ReBar support.
Krizby
TBH the only thing re-bar did for my 3090 is having constant crashing in WD Legion 😛, had to disable it with NV inspector. The only games that have some performance improvement are AMD sponsored games, so yeah, what is the point? I would rather have Nvidia reserving software engineers to expand DLSS game library
Horus-Anhur
The point is having a performance increase. Especially at a time when it's almost impossible to buy a GPU at decent prices.
I don't care about Death Stranding, FC New Dawn and Watch Dogs Legions.
But a performance increase, even if small, would be welcome in HZD, CP2077 and Borderlands 3.
So it would be a net positive for me.
Cryio
Tested HZD with driver 21.8.2 (ReBar not officially supported, but enabled in BIOS anyway) and 21.9.1 (Rebar now officially supported in driver) on my 5700 XT.
Close to zero differences. Same average. Max FPS some 14 fps higher (130 vs 144 I believe? with my tested settings), min FPS increased from 2 fps to 42.
Meh overall.
Horus-Anhur
WTF. You just got a huge increase in minimum frame rate, but you say it's the same.
That's the most important metric for smooth gameplay.
Krizby
Nvidia has whitelisted a total of 19 games in the driver, outside of those 19 games you might experience negative scaling with Re-Bar enabled in the BIOS, even some whitelisted games have negative scaling like WD Legion and Hitman3
I think Nvidia just ditched the whole Re-bar overall, the whitelist games grew 2 titles in the past 5 months (from 17 to 19 games)
Horus-Anhur
So what, I can enable or disable ReBar on my motherboard in less than a minute.
If I'm playing a game that has a benefit, I would just turn it on.
