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

"boot device not found" if I try select the boot drive (F11) I just get a message no OS is found. NVMe drive too. No sound cards just a TV capture card wonder if thats the problem

Nevermind changed windows to GPT after following that guide... then set the bloody bios... at last. Finally its showing up. Hurrah. Only took a couple of hours lol.

Now to see if it makes any difference whatsover...

Well I went from 85fps to 114fps in Skyrim SE... WOW I'll take that thanks very much

That was a nice jump but I'm still not doing this a simple dri er update yes updating bios etc not worth it for me to many things can go wrong for me.

That's not down to ReBar, surely? Nvidia have only whitelisted it for 17 games and Skyrim is not included. Maybe the BIOS update fixed something as that's a huge performance increase, far bigger than what you'd get with ReBar.

I would check your Skyrim graphics settings. I thought I had a similar jump in Jedi Fallen Order but turns out the graphics settings had turned themselves down following the update of the BIOS / GPU BIOS / Driver. Once I was back at max settings I was getting maybe an additional 5 fps at absolute max (from 60 to 65 fps) at 4k on my 3070FE. What was more noticeable however was the lack of stuttering that I used to get occasionally.

EDIT: Hard to say for sure if FPS had increased as there's no benchmark in the game...
 
ASUS were one of the first out with it. At least from an AMD perspective, but my board had a BIOS for it in January:

 
Has anyone got it working with the z390 beta bios? I've got it turned on in the BIOS but nvidia control panel says it's not enabled

edit: Ignore. I had to update the GPU VBIOS.

CB have their resizeable BAR article out

Looks like in their case of a RTX 3080 vs a RX 6800 XT, AMD seems to gain more often.
Actually since Nvidia employ a whitelist it is strange that record any regression at all.

From that chart we can see why Nvidia hadn't bothered to implement it until AMD forced their hand. It benefits AMD much more with a number of bigger increases over 10%.

This has been known for a while, but I am glad to finally see some proper testing being done on this.

I would expect SAM to improve as well and root out those few games that show no performance increase or a slight regression in time.

Would have been nice if they had also tried other cards. Wondering whether some of the even more VRAM-starved Nvidia cards would benefit from a larger window (their new GPU testbed with the 5950X has 4 x 8GB in case 32GB makes any difference).

AMD do a lot better and in some of the outliners, you have to question why Nvidia whitelisted them

as for the others:

and

In Cyberpunk the 6800 almost catches up.

Horzon Zero Dawn is probably the worst one for AMD here.

The real question as with anything in 2021, how would titles developed for the new consoles perform?

That would explain why my 6900 XT overclocked was 30%+ faster than the 3090 in COD Black Ops at 4K.

It was only when the 3090 used DLSS that it caught up.

In answer to your question I've no idea. But i would expect SAM to improve from where it is now.
 
CB now did a Geforce vs Radeon comparison:

and 2160P

I guess that will now be their baseline and no separate entries for BAR / SAM on and off.
Good.

There should be no reason to disable SAM for AMD systems (looking at you Hardware Unboxed :)) as it's a free performance lift in most games and as you can see, it puts the 6900 XT level with the 3090 at 4K and ahead at resolutions below - whilst drawing less power.
 
Quick question.

I enabled mine a while back after stumbling on a video for my mobo, in NVCP it says resize bar enabled however ive seen a number of posts on here stating something needs to be disabled for it to work.

am i good to go or is there something more I need to do.

Help appreciated.

If the control panel says its on, its on. With mine if I enabled rebar in the bios it automatically disables the other stuff (CSM).
