How to Improve Performance (low FPS fix)

Introduction, Test System: This guide is aimed to provide guidance on graphics setting in the game. Mark ones that have the most and least impact on performance so that you can tune your settings to get the most quality possibly on your hardware.

The game tested on the following configuration:
AMD 5800X3D
64 GB RAM
RTX 4090
4k Resolution

Quick Fix

Clouds Quality – Medium or lower
Volumetrics Quality – Medium or lower
Global Illumination – DISABLE

Methodology

• 0 Population
• Game on Pause
• Camera is pointing in the way to have horizon line on top 10% of the screen
• Trees, roads, water, sky, mountains in line of sight
• Save file (TODO: share the save file)
• V-Sync DISABLED

FPS measurements taken from Steam’s FPS counter over 10 seconds. Top and bottom 10% are discarted, then arithmetic mean is taken between lowest and highest remaining results.
