Sure, I did have it verified as operating.  I have it operating now.  I think the differences must be somewhat subtle, at least for my display and my vision.  I feel like I already have perfect crispness, essentially.  But sure will test it out some more.  GPU is up from 37% to around 61% now and I have beaucoup VRAM still.

Glad you got it working and can now evaluate if you want it or not. Did you try your DSR 4x setting that you had enabled in NCP previously as well as the DLDSR 1.78x that we have been recommending?

If they all look the same to you, then you can happily leave everything as normal. This is ultimately all subjective, and should be evaluated with all other settings the same (as you mentioned lowering your LODs).

Personally, whenever I forget or simply don't bother to activate the higher resolution, I feel like I'm looking at the sim through smudged glasses. Not because it looks bad, but because it looks that much better to me when I activate the DLDSR resolution. Sometimes that's fine because I'm only loading in to test something, or I am not flying for long, but I always notice it.

I just tried the 2.25x.  I saw the difference just now with the smaller in diameter taxiway lights in a dawn flight.  But...I had a substantial loss of fluid motion.   Went back to native 3440x1440, all better.  Back to 5160x2160, bad again.  I'll try again with a fresh boot and launch, presetting it before starting MSFS so will leave it in 2.25x mode.  If there is a hint of loss of fluid motion I'll likely be happy with 3440x1440.  And once again, the biggest areas of poorer visuals come from low resolution textures on the ground and those do not improve with DSR.  Everything else is crisp here even at 3440x.

Did 1.78x get chosen because of this loss of perfection motion happens with 2.25x but not with 1.78x?

Thanks again for the help!

Both @Cpt_Piett and I have written in this thread about the fact that 1.78x is plenty and that 2.25x isn't needed. The loss of fluid motion could be due to the requirements on the GPU, the VRAM requirements or a mismatch between the sim resolution and the display resolution in the NCP (I find it easiest to set it in the NCP). That's because GSYNC only works when the two resolutions are the same. So if you increase the resolution in the sim, be sure to also set the Display resolution in NCP to the same resolution.

Do you guys see significant difference at the higher resolution?

There's a difference, which is especially apparent when looking at cockpit instruments. The difference is not so apparent on ground and cloud textures when up at altitude - but there is certainly a difference when looking at objects up close. 

These are two zoomed-in screenshots. One is 5461x2880, the other one is 3240x2160 3840x2160.

Can you tell which one is which?

An important thing to note is that when taking screenshots with a DLDSR resolution, the post-processing done by the Tensor cores (i.e. AI) will not be included in the screenshot. Hence it's not possible to capture the improvements in detail, edges, and shimmering of the image. 

Another thing to note is that the deep learning filter produces an overly sharpened image. This can be mitigated by the setting DSR Smoothness in NCP. The lower the value, the more sharp the image will look.

I don't think there is any other way to do it because you don't have the resolution option in the sim unless you've checked that resolution in NCP.  I checked 3 different DSR options, 1.78x, 2.25x, 4.0x, therefore all 3 of those options become options of resolutions to choose in-sim, so you can't go wrong there.  We'll give 1.78x a whirl and see how that works.  I have 24Gb VRAM and not seeing over 17.5 or so.

After enabling the DSR resolutuons in NCP, you still need to match the display resolution to the sim resolution. In the NCP there's an option to Change Resolution under Display in the menu list. You need to match that to your sim.

Yes as mentioned I saw a difference in the size of taxiway lights, so at least I know it's working.  Yes, when you zoom in close, but that's not what I ever do in cockpit.  And even zoomed in, the difference is there, but it's not huge to my perception.

But NCP allows you to choose multiple DSR options.  Those DSR resolutions will not become visible to choose in the Display dropdown.  This is why I say you can't possible not chose the correct resolution.  When you choose 5160x2160 as a DSR choice in NCP, only then will 5160x2160 become a choice in the Display resolution in-sim.

There is a resolution option in NCP to change the active resolution that the display is set to. The DSR options that you enable are something you do only once. The display resolution is something you need to change every time you do so in the sim for anything above your native resolution (pr back to it). Please look at this screenshot to see the option that I have been trying to explain: https://imgur.com/a/7gfMrlz.

What @mmcmah said. I think I mentioned in a post in this thread that I noticed a significant increase in mainthread frame times going from 1.78x to 2.25x. This could very well cause less fluid movement as you know, even with a 4090 with FG on.

Yep, well we'll give 1.78 a try manana.  As long as it doesn't threaten Nirvana I'll take it 🤞

I had an issue where by in the NVCP resolution setting of 5461x2880 I could only select 60Hz refresh rate and not 120Hz. Maybe this is a limitation of my Sony X90K so for me Nirvana is TAA, 100Hz, FG, Render scale at 105 & 80FPS locked in RTSS.

It is crazy smooth as there is very little deviation with the FTV. I didn't think my experience couldn't get any better but it did a few days ago after I discovered I could use RTSS again to externally lock FPS !

Shoot!  Okay I'm at 1.78x now and definitely see the difference even in the grass clumps ahead of the plane!  But panning is choppy now!  I'm not looking at main thread times, just main thread in use, and it's really about the same, so I don't know why the choppy panning.  So back to 3440x where it remains liquid smooth.  Anything else I can do to fix the choppy panning?  And I only have the one option chosen in NVCP, the 1.78x.  The load on GPU and VRAM is great, but again choppy!  Maybe just need a better CPU?

Oh yes I missed changing the display resolution, I just selected 1.78 as a DSR factor, changed resolution in-sim, but did not selected it in display resolution, which I just did thru NVCP and ....VOILA!  No more stuttered panning.

Thanks!!!!  Looks great!

So of course had to try 2.25x now that mmcmah fixed me.  And it's performing great too!  I guess the consensus is 1.78x is good enough?

Edited February 26, 20242 yr by Noel

@Noel 1.78x is good enough for me. Any higher and the benefits in visual quality are outweighed by performance loss due to extra load on GPU + increased main thread frame times. 

Re: the choppy panning - did you check G-Sync was working with the new settings? I encountered this and it took me a while to realize the monitor had stopped syncing with the GPU.

Could be a variety of reasons I guess. Maybe check CPU cores to see if they are maxed or if there's thermal throttling.
