before you mess with stuff, save your game folder..
- go to


- copy the whole folder called Euro Truck Simulator 2
- paste it somewhere safe (USB, another drive, or just a backup folder on desktop)
this folder has:

• profiles > all your saves
  
• mod > every mod you installed manually
  
• config.cfg > your settings
  
• game.log.txt and game.crash.txt > logs

if OneDrive is syncing your Documents folder (Win10/11 loves to do this), move the whole “Euro Truck Simulator 2” folder to a LOCAL Documents folder, not the OneDrive one. otherwise OneDrive will lock files while the game runs and boom, instant CTD.

turn OFF overlays before testing:
- Discord overlay > User Settings > Game Overlay > toggle off
- NVIDIA overlay > GeForce Experience > Settings > In-Game Overlay > off
- RivaTuner (RTSS) > turn overlay off
- Trucky overlay > disable

then in Steam: Library > Right click ETS2 > Properties > Installed Files > Verify integrity. this checks and redownloads corrupt files.

also go into your profile editor (ETS2 > Profiles > Edit) and untick “Use Steam Cloud”. keep saves local until you’re stable.

logs are your black box..
path:
inside there:
- game.log.txt > spammy log, shows everything game loaded up to the crash
- game.crash.txt > only appears if the game actually crashed hard



tip: delete the old game.crash.txt, then run the game and let it crash again. you’ll get a fresh crash file.

if game.crash.txt is missing, the game didn’t crash itself, something outside killed it (antivirus, driver, Windows).

you can force longer logs by adding this in Steam > Properties > Launch Options:

stuff you’ll see at the bottom:

→ missing/corrupt mod file

→ mod definition missing

→ you removed a mod truck/trailer but still own it in save, or TruckersMP banned item

→ overlay or GPU driver problem

→ usually mod conflict or corrupted save


to scan logs fast, open them in Notepad++ and use regex search. example:

mods are crash city..
- red text mods in Mod Manager = remove them, they are incompatible
- update every mod, especially map/traffic/trailer mods after game patch
- if you remove a mod truck, SELL it first in-game. if you just delete the .scs, your save will crash looking for missing parts
- check folder only .scs files go here. delete junk/old zips
- check if random dlls (like dxgi.dll, telemetry plugins) are left behind from mods, delete them

testing flow:
- disable ALL mods, start vanilla
- if game works → add mods back one by one until it breaks
- for map combos: follow the exact load order from ProMods/RoExtended threads. wrong order = crash

- “Save incompatible” → you loaded it in a newer version. can’t roll it back. only way: restore backup from Documents
- profile missing → OneDrive moved your folder. fix by moving it back to
- no jobs in Freight Market → economy reset:

Method 1 (config):

find → change to 1 → save → launch game → load profile → it resets → game auto flips back to 0

Method 2 (console):
enable console: open , set → "1"
in game: press ~ → type → enter → save → exit → reload → set back to 0

new version out = half your mods dead
- don’t use your main profile in beta builds
- if you roll back game in Steam → Properties → Betas → pick version, make sure you also roll back your saves, check: - reset config: rename → let game rebuild
- large map combos: edit to “50” in config.cfg

- do a CLEAN install of GPU drivers (use DDU or the clean install checkbox in NVIDIA/AMD installer)
- disable DSR, RTX Dynamic Color, overlays
- if it keeps dying with d3d11 → try OpenGL: Steam → Properties → Launch Options →
- force game to use dedicated GPU (Windows Settings → Display → Graphics → add eurotrucks2.exe → set to High Performance)

- Convoy crash = someone’s mods don’t match. every file must be identical
- TruckersMP crash = you’ve got banned parts. remove them
- Firewall/antivirus: allow eurotrucks2.exe
- Plugins: check for old junk (dxgi.dll etc)

these are the hidden startup commands you can throw into Steam → Library → Right click ETS2 → Properties → General → Launch Options.
they tell the game how to start up and how much memory to grab. use the one that matches your PC or laptop..

basic commands for everyone:

(skip the logos, write bigger logs, force DirectX 11)

if you crash a lot on DirectX → swap dx11 with:

(this makes it run on OpenGL, sometimes more stable on older GPUs and laptops)

memory settings by RAM:

• 4GB RAM (old laptop / low end pc):
  
  -mm_pool_size 2048 -mm_max_tmp_buffers_size 400
  
  
• 8GB RAM (average gaming laptop / mid pc):
  
  -mm_pool_size 4096 -mm_max_tmp_buffers_size 1000
  
  
• 16GB RAM (modern mid/high pc):
  
  -mm_pool_size 8192 -mm_max_tmp_buffers_size 1000
  
  
• 32GB RAM or more (high end rigs):
  
  -mm_pool_size 16384 -mm_max_tmp_buffers_size 2000

these options help with “out of memory” errors, huge map combos, and long hauls with lots of mods. don’t just copy random numbers – pick the one that matches your RAM.

sometimes you don’t wanna read walls of text.. here’s the short version.
do these one by one.. this works on gaming PCs, low end laptops, even potato rigs.

1. Backup your saves → go to C:\Users\<your name>\Documents\Euro Truck Simulator 2 copy the whole folder to a safe spot (USB stick, desktop backup). this has your profiles, mods, and settings.
   
2. Kill OneDrive → if your Documents folder is inside OneDrive, move ETS2 folder back to local Documents. OneDrive syncing = constant crashes.
   
3. Steam Cloud OFF → in the profile menu, untick “Use Steam Cloud” so everything saves locally while testing.
   
4. Turn off overlays → Discord overlay, NVIDIA overlay, RTSS/Afterburner, Trucky. all of them cause CTDs.
   
5. Verify game files → Steam Library → Right click ETS2 → Properties → Installed Files → Verify integrity.
   
6. GPU driver clean install → download latest from NVIDIA/AMD, choose “clean install”. old drivers and junk settings cause half the crashes.
   
7. Start fresh profile → make a new vanilla profile (no mods). if that runs fine, problem is mods not the game.
   
8. Add mods slow → enable one by one. fix “failed to open file” or “unit not found” errors before adding more.
   
9. Empty jobs? reset economy → edit config_local.cfg or use the console with
   g_force_economy_reset 1
10. Still broken? → grab
    game.log.txt
    +
    game.crash.txt
    from Documents and post on the SCS forum or Reddit r/ETS2. they’ll tell you which mod or setting is killing you.

- Game won’t launch at all (nothing but a small window then closes)
→ Steam → Verify files
→ open set (forces windowed)
→ turn off overlays (Discord/NVIDIA/RTSS/Trucky)
→ try OpenGL: add to Steam launch options

- Crash with d3d11.dll or dxgi.dll in crash log
→ overlays off (Discord, GeForce overlay)
→ clean reinstall GPU drivers
→ if still broken, force OpenGL with

- Crash with ntdll.dll in crash log
→ usually system file mess. run Windows tools: open CMD as admin → type
→ if errors, follow up with

- “Failed to open file” or “unit not found”
→ bad or missing mod. update/remove it.
→ check you have all parts of a map combo + correct load order.

- Empty job market (no Freight/Quick Jobs)
→ reset economy. open inside your profile folder, set , launch once, then it resets back.

- Crash right after update/patch
→ mods broke. disable all mods, wait for updates.
→ or rollback ETS2 in Steam → Properties → Betas → pick older version.
→ use profile backups from if your main save is dead.

if your game dies right after hitting play, black screen then desktop, or it freezes at the loading bar:
- verify files in Steam (Library → Right click ETS2 → Properties → Installed Files → Verify)
- check , set to force windowed mode
- disable Discord / NVIDIA overlays, they are #1 cause of “ETS2 crashing on startup”
- if you see d3d11.dll or dxgi.dll in the crash log, swap renderer with in Steam Launch Options
- old laptops or integrated GPUs especially need this

this section also applies if American Truck Simulator won’t launch - same fixes, just swap the Documents folder name.

a lot of players search “ETS2 crashing after update” because every big patch breaks mods. common stuff to do:
- disable all mods, start a clean vanilla profile first
- update map mods (ProMods, RoExtended, RusMap) — outdated maps = instant CTD
- rollback game version in Steam if your favorite mods haven’t updated yet (Library → Properties → Betas → select old version)
- check your save backups in if your main profile says “incompatible”
- if the game still crashes after patch, delete in Documents, game will rebuild a fresh one on launch

same deal for ATS - patches break mods, so test vanilla, then bring mods back one by one.

Q: ETS2 not launching on Windows 11?
→ Go to Step 10: Mini Decision Tree. Set r_fullscreen "0", turn overlays off, and try -rdevice gl.

Q: How do I fix Euro Truck Simulator 2 out of memory errors?
→ See Step 8: Launch Options and pick the pool size that matches your RAM. Also change uset r_buffer_page_size "50" in config.cfg if you run big maps.

Q: American Truck Simulator won’t start after an update, is it the same fix?
→ Yes. Same exact steps, just the folder is Documents\American Truck Simulator. Check Extra: ATS Fixes.

Q: Where is the ETS2 save game folder?
→ C:\Users\<your name>\Documents\Euro Truck Simulator 2\profiles. Covered in Step 0: Backup & Prep.

Q: What does g_force_economy_reset 1 do?
→ It resets your job market when it’s empty. After running once, it flips back to 0. See Step 4: Profile Issues.

Q: Do I need to reinstall ETS2 to stop crashing?
→ Almost never. Crashes usually come from broken mods, OneDrive syncing, or GPU drivers. Try Step 3 (mods), Step 6 (graphics), and Step 7 (multiplayer) first.
