Update the DLSS preset used by DCS to remove ghosting

[Nighthawk 117]

After todays patch if you have the Nvidia App you can now select the preset on there

No longer required either. Add the below line to your C:\Users\Saved Games\DCS\Config\autoexec.cfg file (create it if it doesn’t exist) to set the preset for DCS

DLSS_Preset = "K"

You can add this line as well if you don’t want DLSS applied to MFDs and HUD to keep them sharp with no ghosting for greater control.

HUD_MFD_after_DLSS = true

Is there any downfall / sideeffects to using this? Does it take up more GPU or CPU resources? (Just wondering why this isn't done by default with DCS and/or why this is hidden away to implement instead of being standard and what I should be aware of before implementing it).

May be minutely GPU hit compared to using nothing at all. Yes, this is “hidden” away (should have been better documented in release notes). The second option is not everybody wants DLSS for MFDs due to the ghosting it can cause with cursors etc on radar screens and other things. I reckon it’s a great addition and compromise.

Youre right though, it could have defaulted to K instead of C and people could override if they wanted to. The K (and J) presets are going to be a little less performant than some others.

Haven't tested yet but I suspect it might leave it with no AA which makes it clear but aliased and shimmering.

I have the latest GeForce v. 576.52 drivers installed. nvngx_dlss.dll v. 310.2.1.0 file. Regardless of whether I use the 'K' preset in the NVIDIA application or use the entry in autoexe.cfg, I still experience ghosting when using DLSS.

Does anyone have any ideas where the problem might be?

Ghosting is normal part of every temporal AA method. They can only reduce it. If you can't live with the effect you have to go with other AA tech.

@draconus Thanks for the reply. I thought I was doing something wrong or messed up the settings. It doesn't bother me much. I got interested in it because it's been a hot topic lately.

The only only way to get rid of it (that I have found) is to push resolution as high as possible. I see you have a quest 3. Have you tried using Quad Views Foveated Rendering? I push the foveated resolution up to about 5000 pixels (equivalent) and this virtually eliminates ghosting.

I don't use VR goggles, I don't know what you were suggesting. Could you write this in a clearer way? For someone who has no idea what you're talking about.

Sorry. I looked at the wrong signature.  Ignore me.

I have to turn off DLSS/DLAA completely so I don't get ghosting.  Ryzen 7 78003d, 4090 GPU, Pimax Crystal Flight version VR.

Running Preset K for DLSS? Remember, it gets reset every Nvidia update..

Not if you use autoexec option in DCS.

Have you tested these settings?
