@mmcmah Interesting that there's almost no performance impact 4K vs. 1.78x. Mainthread frame time is even lower with 1.78x, lol. Also, that's a good demonstration of how huge impact AI traffic has on mainthread. Which is why I've decided to use 4K when flying into LAX and similar major hubs with traffic. Without AI traffic, I can run 1.78x at iniBuild's LAX, no problem. 

@Farlis, after selecting 1.78x and 2.25x in NCP, change the resolution (NCP) and at the top you will see the two DLDSR resolutions. Choose one of these.

Then, in MSFS, you'll have these two resolutions available. 

I have my normal 4k (3840X2160) res selected in my NCP and have 5760X3240 selected in the sim. Do I need to have them both selected for it to work?

You should set them to the same resolution. That will allow two things to happen: GSYNC will vary the frame rate correctly and your developer UI text menus will work correctly because the scaling will be correct. However, it will make your text very small for any window opened from you main monitor. Also, for the above reason, 1.78x might be good enough without jumping to 2.25x (in addition to reduced overhead and VRAM usage).

Thank you for the clarification!

 

I'm confused!  I have had DSR Factors set to Legacy 4.0x even with my 3080Ti and the impact to the GPU wasn't there.  Was I also supposed to do something else?  I use TAA and the highest settings in MSFS, 8xSS, 16xAF.  I thought I had great sharpness quality but wonder if I'm missing more because as I say there is not real impact on the GPU.

Cheers

Feel free to leave it on 4x, but you might prefer the DLDSR settings of 1.78x or 2.25x better (and they're less taxing).

If you're not seeing a hit to the GPU, maybe you haven't selected the 4x resolution within MSFS?

If you mean Render Scaling, yes I left that on 100.  My sense was DSR does not depend on render scaling change, or perhaps it's that it reverts the NVCP DSR back to no DSR?  And very aware higher render scaling values put demand on the GPU which is why I was using DSR.

I'm not sure what you aren't seeing. I thought you weren't seeing a hit to your GPU from a 4x Legacy DSR factor. Based on what I've seen (never tried it myself), that should put a definite strain on your GPU. What I was suggesting is that you make sure that your in-sim resolution (above the Render Scaling setting) matches your 4x DSR resolution.

I'm not sure what you're saying.  As I said, I keep RS at its default 100 in sim.  I set DSR factors in NVCP to legacy 4.0x, or 6880x2880.  In its Description it says "DSR can be applied to any game....and can be used with other antialiasing settings..."  It makes no mention of changing anything in game to make to work.  There no substantial GPU impact doing this.

That's because you aren't driving the higher resolution. You enable it in NCP. Then you have to activate it in the sim. You change the resolution in the sim to match the NCP resolution that you enabled. Be sure to also change the NCP resolution to use the one you're using in the sim so that GSYNC works correctly. Don't change the render scaling (leave it at 100).

Very good I'll give it a try.  Thanks!

Interesting.  I have it set up correctly, it's hitting the GPU now, and I'm using the 5160x2160.  Quite frankly, can't really see much if any difference.  The real villain here is not more resolution from the output side, but better resolution of the native textures:  does no good in increase output when the source is low budget, which so much of the scenery is.   

Thanks for the education I clearly didn't know what I was doing.

Agreed. I removed the 2.25x option from NCP. Btw I also changed the scale (text, apps etc) in Win display settings.

Me too, I would have expected 4.0x to have a significant impact on performance. Did you choose a higher resolution in MSFS as well as setting DSR in NCP?

Exactly. It doesn't add up - if I choose DLDSR 2.25x the 4090 is running at 99-100%. 4.0x legacy scaling using DSR on a 3080Ti doesn't make sense. Unless upscaling from a lower resolution than 4K. 

I do it like this: enable DLDSR in NCP, select either 1.78x or 2.24x as a new resolution in NCP then select the same resolution in MSFS. 

If I check in the Win display settings I see this: 

MSFS dev mode OSD should also be reporting the higher resolution.

Do you guys see significant difference at the higher resolution?  I have to try again but I'm always struck by the low resolution of some of the native textures and you can't make that better.  I tried the 2.25x at 5160x2160 or whatever it was and wasn't sure if anything looked different.  But my LODs were down too.

Yes, I see pretty significant differences. Did you at least confirm that you're seeing the higher resolution and that your GPU is now being driven harder? You should also make sure that you have enough VRAM for the higher resolutuon, as havibg too little will cause the textures to look bad.

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.
