Engine.ini for DNA (for Reddit)

Engine.ini

# Credits to DragonPhase for the base file for this. Comments below starting with ; are theirs.
# No link here to the original to avoid breaking TOS (I sourced it from a mod-hosting site).
# My main changes were some auditing of changes to make sure they 
# actually decreased (or did not increase) frametime.
# I also did a sweep to remove changes that changed visual quality for the worse;
# you can absolutely make DNA look worse than this.
# Warning: this version may cause nasty blurriness when FSR is enabled.

# This was made using the 1.0 Fina patch, 11th Dec 2025.
# Important: the devs can and will change optimization over time!

# HOW THIS WORKS
# Unreal Engine has internal settings that are controlled via text-based settings, called cvars.
# These settings add overrides to what some of the settings do. Most of these changes are benign tweaks.

# INSTALLATION INSTRUCTIONS
# Find your Engine.ini file - [DNA install location]\DNA Game\EM\Saved\Config\WindowsNoEditor\Engine.ini
# Open it, copy-and-paste the below in to overwrite what's already there, then save the file.
# Maybe back-up the original version first.

# UNINSTALLATION INSTRUCTIONS
# Literally just delete the Engine.ini file above. The game will regenerate it from its internal defaults when it boots up next.
