Metro Exodus has a raised black floor, which makes the game look washed out.

Luckily, this is a simple fix. Just add -deependark to Steam launch options. The difference is night and day.

With the release of DLSS 4 Nvidia added new DLSS tweaks to its app.

1. Open Nvidia App
   
   
   
   
   
   
   
   
   
   
   
   
2. Navigate to Metro Exodus EE settings, as shown here. Choose DLSS Override - Model Presets. If it's grayed out, make sure you have the latest GPU driver.
   
   
   
   
   
   
   
   
   
   
   
3. Change the setting to either Latest. This will update DLSS to the new Transformer model. It offers better quality, but decreases FPS over the old model (CNN).
   
   
   • Older RTX cards, such as 2000 and 3000 series may loose quite a bit of performance with this model.
   

If you still experience some ghosting, or notice a big FPS hit, choose Preset E from the section below. It's still the latest DLSS version, but with the CNN model. That one works for my RTX 3070 significantly better than Latest, although Nvidia constantly updates DLSS, and this may change in the future. Test manually.

If you've previously used DLSS Tweaks, and are familiar with DLSS Presets, you can also change them here.
A quick explanation:

• Preset A - Intended for Perf/Balanced/Quality modes: An older variant best suited to combat ghosting for elements with missing inputs such as motion vectors.
  
• Preset B - Intended for Ultra Perf mode:Similar to Preset A but for Ultra Performance mode.
  
• Preset C - Intended for Perf/Balanced/Quality modes):Preset which generally favors current frame information. Generally well suited for fastpaced game content.
  
• Preset D - Intended for Perf/Balanced/Quality modes):Similar to Preset E. Preset E is generally recommended over Preset D.
  
• Preset E - Intended for Perf/Balanced/Quality modes)The default preset for Perf/Balanced/Quality mode. Generally favors image stability. Go-to for DLSS 3.
  
• Preset F (Intended for Ultra Perf/DLAA modes):The default preset for Ultra Perf and DLAA modes.
  
• Preset G (Unused)
  
• Preset J is the new DLSS 4 Transformer model from last week.
  
• Latest (K) is the latest DLSS 4 Transformer model

However, it's up to Nvidia to enable the option. Some games are unavailable for now, but this may change with future updates.

Deep Learning Anti-Aliasing (DLAA) is very simply put, DLSS at your native resolution. Instead of increasing FPS, it increases visual quality.

If your PC is powerful enough to handle Metro Exodus EE without DLSS, use DLAA instead. It has a performance hit, but offers substantially better quality in motion than TAA (Which the game uses if DLSS is off).

In Nvidia App, open DLSS Override - Super Resolution. There, choose DLAA (100%). Either Latest or Preset F are recommended for it.
DLSS has to be enabled in-game at any quality for it to work!

Default DLSS Quality. Ancient DLSS version and horrid ghosting vs Latest setting (Transformer). New DLSS version, significantly reduced ghosting and a minor FPS hit:










New DLSS version, Preset E (CNN), no ghosting at all, actual FPS gains (May be different for everyone, please test yourself) vs DLAA:




Finally, Native resolution, DLSS/DLAA disabled.


So this is a bit complicated, but here's how to enable/disable DLSS debug overlay. It shows advanced DLSS info.

Download this[drive.google.com] and run the respective file to enable/disable the overlay.


If you're suspicious of running .reg files from an unknown source (which you should be. A shady person could do a lot of harm with that, down to breaking Windows entirely), extract the files and open them with a notepad or other text editor to see what they do.

They create a reegistry value in [HKEY_LOCAL_MACHINE\SOFTWARE\NVIDIA Corporation\Global\NGXCore] named ShowDlssIndicator with a hex value of 400 to enable, or 0 to disable the overlay. If you know how to edit Windows registry, you can create the value yourself. It's DWORD (32 bit), 400 hex or 1024 dec. 0 disables it.

If you've got anything else to add or have questions, comment. I'll update the post if new information comes up.
