Euro Truck Simulator 2: Best config.cfg for Multi-Monitor Sim Setup

The objective is to achieve a perfect 1:1 scale across all displays while minimizing the CPU overhead of drawing multiple camera angles simultaneously.

File Path & Access

File Path: %USERPROFILE%\Documents\Euro Truck Simulator 2\

Step-by-Step Instructions:

1. Press Win + R on your keyboard, paste the path above, and press Enter.
2. Locate the file named config.cfg. (Always create a backup named config_backup.cfg before editing).
3. Right-click and open with Notepad or Notepad++.
4. Find the variables listed in the configuration block below using Ctrl + F.
5. Update the values to match the “Sim-Rig” profile.
6. Save the file and launch the game.

Optimized “Triple-Monitor” Configuration Block

uset r_multimon_mode "2"
uset r_buffer_page_size "50"
uset r_deferred_mirrors "2"
uset r_scale_y "1.0"
uset r_scale_x "1.0"
uset g_menu_aa_limit "0"
uset g_lod_factor_pedestrian "15"
uset g_lod_factor_parked "15"

Parameter Details & Technical Purpose

Parameter	Recommended Value	Technical Purpose
r_multimon_mode	2	The Multi-View Fix. Enables multi-frustum rendering (Mode 2 is for standard triples, Mode 4 for advanced custom setups).
r_buffer_page_size	50	Increases the memory buffer for loading assets, preventing “hiccups” on high-res multi-monitor spans.
r_deferred_mirrors	2	Enhances mirror quality for peripheral monitors, vital for realistic trailer maneuvering.
g_menu_aa_limit	0	Disables AA in menus to prevent UI flickering on ultra-wide resolutions.
g_lod_factor	15	Increases the draw distance of objects to prevent distracting “pop-in” on side monitors.

Best Practices for 2026 Sim-Rig Stability

To achieve the ultimate immersion and performance on your multi-monitor setup, follow these additional GameEngineer.net technical steps:

• Multimon_Config.sii Setup: Setting r_multimon_mode to “2” creates a secondary file in your profile folder called multimon_config.sii. You must edit this file to input your exact Bezel Width and Monitor Angle (e.g., 45 degrees). This ensures that a straight road looks straight across all three screens.
• The “Scaling” Trap: In 2026, with high-resolution screens, many players use 400% scaling. On a triple-monitor setup, this will crush your GPU. Set in-game scaling to 100% and use NVIDIA/AMD Super Resolution or AA via the config.cfg for better results.
• Vertical Sync (V-Sync): For multi-monitor setups, standard V-Sync often causes “tearing” on the side displays. Disable in-game V-Sync and use your GPU driver to enable Fast Sync or G-Sync/FreeSync for the entire display span.
• TrackIR / VR Latency: If you use head-tracking alongside your multi-monitor setup, ensure g_hmd_no_limit is set (if using VR) or increase g_input_number_of_controllers to properly map all your sim-rig peripherals without input delay.
