Yup, as long as you are using nvidia driver 572.xx.  If you use previous drivers, then you need to copy the DLLs.

I tried the suggestion in the recent couple of pages, it works.

1. Get the latest NVIDIA gaming driver, it is also recommended for VD users;

2. Get the NVPI (I think I get the developer right): https://github.com/Orbmu2k/nvidiaProfileInspector

3. Start the NVPI and perform the settings as seen in this post 

BTW, you may wish to also make changes to the ultra low latency and power management settings en route.

4. Of course, don't forget to select DLSS in the upscaling in DCS.

That's, yes, that's. I don't have to make a video about it.

But from what I understand, what it does is apply a common DLSS configuration (preset K in this case) to the entire computer. Or am I wrong?

I do not think this is the case, as you use NVPI to change the game profile, not the global profile.

yes, it's right my friend. I didn't think on this.

OK & just to clarify: I am using version 2.4.0.16 of inspector. Here is my settings, in common, it says "Forced DLSS3.1 preset letter K". We are talking about DLSS 4 here arent we, so why does it say 3.1?

Secondly, how do I get rid of the annoying text in my VR FoV - its some kind of debug info, says Preset K etc......

If you have DLSS swapper - in settings DLSS Developer Options - Show on screen Indicator to None

Short response from my side after some testing.

Even Im leaning towards AMD, since Nvidia to me just is utterly anti-consumer company (false promises (5070 has 4090 perf), fake MSRP and skyhigh prices etc) I do have a 4090 since AMD f.. up with their 7xxx generation VR-wise. At least until I got my 4090 midsummer 2023.

Up to now I used MSAA 2x since DLAA was way to blurry for me. So no upscaling for me.

After testing DLSS 4 as shown here, I have to admit, Ill give it a try now.

First of all, there is almost no visible perf difference for me with DLSS4 Quality and my standard no-upscaling with MSAA 2x. I saw a decrease of 0,3ms frametime in my test-scenario. DLSS3 offered about 1 ms less, wich is pretty much IMO. But it all was too blurry/soft for me.

But using DLSS4 now, the previous slight shimmering is gone, while still resembling sharpness of my former no-upscaling with MSAA 2x. Looking outside some objects look even sharper (using 0,8 sharpening right now)

The only thing still looking worse is the radar scanning bar on the DDI in the F-18 . But this also has gotten much better then with DLSS 3.

I dont assume to get problems with ghosting, since Im on 90fps on the G2 most of the time. But I will need to check that too.

Anyway, DLSS4 for me offers some visible gains while up to now only showing minor drawbacks. So I will keep it on for sure. 

Edit: after installing the latest Nv-driver 572.47 I got problems while booting Win10. Went back to 572.16. No problems since doing that, but this still needs some monitoring I guess

When we update Nvidia drivers, do we need to do anything with regards of DLSS4?

Nothing. Make sure just install the drivers and leave the NVIDIA app alone.

Is the consensus Preset K more preferred over Preset K?

If you use the easy global override method (only change settings in Nvidia Profile Inspector, no DLSS swapper tool used, no NVIDIA app needed, no manually copying DLSS dll files), you will always have to check and/or make the settings again after each driver update.

Confirmed, using DLSS tweaks, all my settings returned to default after installing the new driver.

Will DLSS 4 be incorporated into DCS without any tweaking?

They’ve said they’ll look at it after Vulkan.

No, I would say preset K is much better than K 

[Esac_mirmidon]

You are wrong, K preset is better than preset K.

is that so?

[Esac_mirmidon]

Absolutely !!!

[Aapje]

I think that they are pretty much equal. J vs K on the other hand...

[Sn8ke]

Obviously meant J vs K. Lol. So K is prefered? No outstanding issues warranting using J instead?

[C3PO]

After all of this, what is tbe minimum I need to do to get DLSS 4 working with my RTX 3090 - and how do I tell if 4 is implemented/working?

1. Install the latest Nvidia driver (don't install the Nvidia app)
2. Install the latest Nvidia Profile Inspector (https://github.com/Orbmu2k/nvidiaProfileInspector)
3. Select the Digital Combat Simulator: Black Shark profile in the dropdown and then in the Common section enable DLSS - Enable DLL Override and set the DLSS - Forced Preset Letter to Always use latest (the latest is K, so try that and J which are the most common at the moment to see which one you prefer)

To tell if it's working (although you should see a notable difference anyway):

1. Download and unpack DLSSTweaks (https://www.nexusmods.com/site/mods/550)
2. No need to copy any files into DCS, just run the DLSSTweaksConfig.exe file
3. At the bottom of it set the GlobalHudOverride to Enable (All DLLs) and then click Save
4. Start DCS and jump in a plane. Some people say they only see it in 2D but there should be a hud overlay at the bottom left of the screen. Verify the DLSS version, starts with 310., and that the preset is K or J (whatever you chose to use).

If you install a newer Nvidia driver later confirm in NVPI that it kept your settings, you may need to reapply them again.

[Dunska]

You don't need DLSSTweaks to show the DLSS Hud, just use the registry settings:

Set manually or copy this into a .reg file and run it.  For me I only see it in 2D, so I run it in 2D to check.

DLSS Hud On:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\NVIDIA Corporation\Global\NGXCore]
"ShowDlssIndicator"=dword:00000400

DLSS Hud Off:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\NVIDIA Corporation\Global\NGXCore]
"ShowDlssIndicator"=dword:00000000

Correct. I generally just advise a nice UI so people aren’t hacking the registry (that’s sometimes where the “fun” begins).
