@turbomax Thanks for the kind word, much appreciated 🙏

Been doing some testing re: performance comparing 4K to DLDSR 1.78x i.e. 5461x2880. The difference is quite significant. I've got a decent system, so most of the time the increased resolution will not affect performance too negatively. 

However, I was doing some testing at iniBuild's KLAX, and was surprised how much of a performance hit 1.78x brought. I promised not to post any more pictures, so I'll have to manage with words 😉

Using the dev mode OSD: 

                       3840x2160        5461x2880

FPS                62.1                   38.5

Mainthread     16.1ms              24.7ms

GPU                11.7ms              16.9ms

What surprised me was how much the increased resolution affected mainthread. The tests were done without any AI traffic. High mainthread frame times will increase the chance of seeing FG-related artifacts, even though the FG-FPS seems high. In the tests above I had FG on, hence FG-FPS at 5461x2880 was 76. Still the artifacts appeared, especially with fast panning. 

Conclusion: I'll probably use 4K when flying into major hubs like KLAX, especially when using extra addons e.g. FSLTL and GSX Pro.

I'll have to compare. I didn't see any where near that difference at the iniBuilds JFK.

I can not get Ultra Quality to show up at all in MSFS.. The DLL is replaced, NI settings changed, resolution changed.. Nope.. Will this only work for a certain series of RTX cards? There was no mention of it

Did you make the changes in Nvidia Inspector while MSFS was running? If so, you need to restart MSFS when making those kinds of changes.

DLDSR is limited to RTX cards (RTX 20, 30, and 40 series) as it needs their tensor cores to operate.

Did you see the added DLSS settings in NI? I.e. where you set preset F and 0.8x render?

As stated 

Set the DL scaling according to instructions

I replaced the DLL, which was already on the latest version as I replaced it before but did it anyway again just to make sure to follow the instructions

Set NI settings in NI per instruction downloading the CustomSettings, plopping it in the NI directory and setting the settings to the T

Set Windows resolution to 5461x2880

Set MSFS resolution to 5461x2880

Rebooted Windows for good measure

Ultra Quality is not an option under DLSS.. Only Quality  

For those who haven't read my signature. I have a 2080 Ti 

I have MSFS installed into C:\MSFS and the DLL is replaced in the corresponding content folder. 

I'm on 551.61

I don't see any issues with what you've done. 

I recall having some issues with ultra quality when first trying to get it to work. Sadly I cannot recall exactly how I solved it. 

Even though it's recommended to only change settings in global profile, it might be worthwhile checking that the same values are reflected in the MSFS profile.

Yeah not sure what is going on

Did you remember to hit apply changes after changing settings in global profile?

I indeed did... Even even though it stuck by closing and reopening it, I reopened it as administrator and applied the settings again. Rebooted. Nothing..  Only Quality is available.  There has to be some missing link here that is preventing this option from showing.

how about if you remove/rename your older versions 2.4.12.0 so they can definitely not be loaded?

Ok figured it out. 

OP only links to replacing nvngx_dlssg.dll but nothing about also replacing nvng_dlssg.dll

Soon as I replaced the latter I now have Ultra Quality

Great that you figured it out! 

I re-read my guide, and I think the instructions should be legible.

The easiest way is to use the app DLSS swapper that can be found on github. This will only give benefits when not using frame generation though. For those that want FG in combination with the latest improvements in DLSS, the method is to manually replace the current MSFS DLSS version with the most recent one, which can be found here.

I linked to a video by IslandSimPilot that explains how to get the standard DLSS version using DLSS swapper. This is by far the easiest method and it replaces the nvngx_dlss.dll file. When using FG, the file nvngx_dlssg.dll has to be updated, which cannot be done using the swapper. It has to be done manually. 

From the TechPowerUp site that I linked to, the title says "NVIDIA DLSS 3 Frame Generation DLL". In the description it says:

Please note, this download is for DLSS 3 frame generation specifically, the "g" at the end of the filename. The classic DLSS 2 DLL download can be found here.

You're good my friend. I appreciate it! 🙂 The file names with 1 letter distinguishing their differences was bound to cause some headaches..
