It looks different for me

Is there an easy way to check if I have changed the global settings? 

[sleighzy]

@Red_Dragon, you need to scroll down further in DLSSTweaks config tool, you're only seeing the first couple of sections. The global section is at the bottom. The top part of that tool scrolls further, even though the "Welcome to the DLSS Config Tool" section stays there.

In the global overrides section you'll see the GlobalHudOverride option. Change the value in the dropdown to "Enabled (all DLLs)" and then once you're in the game and plane you should see that overlay like in my screenshot which will show the preset you're using.

Should I be seeing that Overlay in VR?  I don't see it.  But I am using OXRTK and I see THAT overlay.

 

Never mind...  I do see the overlay in 2D, so I guess that is better to not clutter up my VR view any more.

With the latest releases of DCS both the bin\DCS.exe and the bin-mt\DCS.exe run the multithreaded version. As DCS could now be running the one in the bin directory (depending on what your shortcuts do) then if you’re using the file based approach you’ll need to copy the dxgi.dll and .ini file to the bin directory as well.

Thank u very much for ths Thread! This was a game changer for me..
for me Preset F is the way to go..

cuts ghosting in VR Quest 3 by half with just 1 click.. i love it!

Long thread so apologies if this has been asked and answered but it’s geared towards VR Users. 

My question is; Does this fix improve things for regular Monitor/head tracking users?

 

TIA

Yes it does quite significantly, at least on my end preset F and DLAA looks great.

Yes, this is just a general graphics setting and is not specific to VR.

Hello, I don't know why but I don't see the overlay in DCS (2D and VR) and I don't see a DLSSTweak log file in the DSC BIN or mt-bin folder. Below are my settings.

I try to copy the DLSSTweak file to the C folder as explained in the simplified approach or the bin or mt-bin folders but doesn't change anything.

I copy/past DLSSTweaksConfig, dlsstweaks and the updated nvngx_dlss.dll files in Bin and mt-bin. Is it right ?

I'm a little lost with nvngx_dlss.dll and dxgi.dll what is the difference ?

Thank you

For the simplified version don't copy any files into "bin" or "bin-mt". This is only required for manual config file changes, if you have stuff in there then it may be overriding the global profile settings (I haven't confirmed this). You only need to run the DLSSTweaksConfig.exe tool for the Nvidia Global settings, no need for extra dlls and ini files, so just go ahead and remove those.

When you ran DLSSTweaksConfig and changed the Global preset to F (and the GlobalHudOverride to "Enabled (all DLLs)" and then clicked the Save button did it pop up a message stating that you needed to be an administrative user and when you clicked Ok it closed and then reopened DLSSTweaksConfig, and then you were able to update those settings and click Save again? You need to restart DCS after these changes. The HUD overlay is also only displayed when actually in the plane, not at the main menu.

The "nvngx_dlss.dll" is the one that ships with DCS and is the Nvidia DLSS library file. You can update this to a later version if you like, but this is unrelated to the "dxgi.dll" file. You only need to worry about the "dxgi.dll" file if you are doing manual config, i.e. dropping dll files and ini config files into the bin and bin-mt dirs. DLSSTweaks comes with an nvngx.dll file, so if using the manual approach this is the file you would drop into bin and bin-mt and then rename to dxgi.dll. The reason for renaming that from nvngx.dll to dxgi.dll is that a few DCS patches ago is that the DLSSTweaks stuff stopped working, renaming that file fixed this.

You also won't get a log file when using the Global Profile setting approach. This is because it is not using the dxgi.dll (renamed from nvngx.dll) file, which is what produces the log file. You will need to use the HUD overlay to verify it is working, you can turn this off afterwards.

Hope that helps, let me know if this still isn't working for you.

Thank you very much is very clear. I can see the HUD in 2D in the plan but not in VR. Is it normal?

I can see in both 2D and VR. It's right down the very bottom left of your headset in VR, maybe you're just not seeing it?

DLSS 3.8.10 has been released https://www.techpowerup.com/download/nvidia-dlss-dll/?amp

Notably based on this article all other presets have been removed and only E and F remain. I’ll test this latest release with DCS using the defaults and see which preset it decides to use.

https://www.tomshardware.com/pc-components/gpus/nvidias-latest-dlss-3-8-10-version-features-only-two-presets-preset-e-and-preset-f-chipmaker-trimmed-the-dll-file-size-by-more-than-50-percent

[sleighzy]

Just tested now using the latest version and not overriding the preset. The debug overlay shows that DCS is now using preset E. This was previously C by default but now that this has been removed it's on E.

[ShroomSister]

Do I need to update my DLSS version, or should I just wait for a future update when DCS is brought up to date with current DLSS? Playing on 2D btw. I switched DLSS off entirely because I couldn't stand the ghosting.

Myself personally, I'd update your DLSS library to this version. Means no need for DLSSTweaks/Nvidia config if you just want to get preset E by default. This should hopefully reduce your ghosting, and who knows when DCS will get around to updating their version of this.

[Cool-Hand]

Yeah this pretty much eliminated all my ghosting, there is still some on very high contrast situations now that I'm playing but nothing like it was previously using dlaa.

[sleighzy]

@BIGNEWY, if DCS were to ship with this later version then my original post here for a request to change the preset would become redundant as we would get this for free. Thanks in advance.

[sleighzy]

Selecting the "Ultra Performance" option in the DCS dropdown will set preset F.

[DCoffey]

Thanks for all the info, I did not realize this had been posted, this is way more informative.

 

Thanks for everyone's work!

[nikola499]

I am a new player and little confused. Do I still need to download and run DLSSTweaksConfig or was it updated by DCS itself and I just need to select "Ultra performance" in DCS?
 

If DLSSTweaksConfig still needs to be ran. Do I run it from desktop or I have to put something in game folder? If so where do I need to put it and does DLSSTweaksConfig need to be ran every single time I launch the game or just once?

 

Thanks for the help in advance

Nothing has changed in DCS. If you don't want to use DLSSTweaks you'll need to replace the bin\nvngx_dlss.dll and bin-mt\nvngx_dlss.dll files with the latest 3.8.10 version found here: https://www.techpowerup.com/download/nvidia-dlss-dll/

Don't bother with selecting "Ultra Performance" at this stage. Whilst it will use preset F (if using the new dll) I imagine it will lose some visual aspects vs. the "Quality" option. I need to retest both options to see just how different they are.

To finish answering all your questions. If you do want to use DLLTweaks, i.e. you don't want to use the new dll and get this for free, or if you want to try preset F but on the DCS "Quality" option with the new dll, then follow the 3 steps of the simplified instructions (the second part of my original post) to update the Global Nvidia Profile config using DLSSTweaks

No need to put anything in the game folder for DLSSTweaks. Just run the DLSSTweaksConfig.exe file from where ever you downloaded it to. Doesn't need to be launched each time, it's going to update the Nvidia config for your PC so will apply to everything.

Thanks for your super fast answer. So basically run DLSSTweaks from desktop folder, change only the preset setting to F, Save it and thats it? Dont have to run it ever again and can launch game after.

I figured it out but I do see the text in game with my VR headset saying Render type F, etc. How do I make that text go away?
