Multiplayer Pre-Alpha - 2021/12/03

Version: 1.2
Size: ~367Mo

Known Issues

  • This patch is aimed squarely at addressing top player feedback on gameplay, crash rates, and performance. We had to make a hard choice between not rolling out a patch for the remainder of the Pre-Alpha, or publish one that fixes these issues but also introduces a visual error. We chose the latter as we want players to have a more fun, stable and better performing game as we head into the last three days of this Pre-Alpha test. Thanks for your understanding and continued feedback!
  • Textures and lighting on buildings are flickering or flat.

General Fixes

  • Fixed some out of memory and gameplay crashes
  • Fixed the missing model for the Flak 88
  • Reduced performance issues while edge panning the camera
  • Added scroll bars to friends lists across all screens.

Balance Changes

  • Panzerschrek penetration increased
  • Jeep HMG penetration increased
  • Kettenkrad capture speed reduced and health decreased

Problèmes connus

Our team is incredibly excited to launch Company of Heroes 3 and to have our players explore the Mediterranean theatre. We plan to spend a bit more time gathering your feedback before we discuss future updates, patches, and fixes. Our goal is to allow you the time to explore and experiment with CoH3 so we can identify the top areas of feedback. We plan to follow-up in a few weeks to address as much as we can! For now, please be aware of the known issues below that our team continue to work on. 

Please also submit Bug Splat/Crash reports as every single report will be read by a developer. They provide us with much needed information for us to resolve issues swiftly. 

Since finalizing the launch version of CoH 3, we have put an increased number of hours towards bug fixing, polishing, and tuning. Once we observe the launch and gather more data, you can expect larger patches to arrive in the coming weeks. 


  • FIXED If you're experiencing an issue where the game fails to launch, please reboot Steam, then verify your game files. Please let us know if this issue persists.
  • FIXED We're aware of a server error that is affecting a number of users playing multiplayer. Our team is currently investigating.
  • FIXED We're aware of a redemption issue for players trying to redeem their CoH3 code they received when purchasing AMD hardware.
  • The Slow and Steady achievement may not unlock correctly.


  • We are aware of two GPU related crashes. We have fixes for these crashes but require more time to test them internally. We plan on releasing a patch with these fixes shortly after launch. Should these fixes cause more instability, we will revert to our 1.0.0 version of the game. These two crashes account for over 45% of all our crashes during our most recent public test.
  • There are ten crashes we are aware of with low reproductive chances. We will continue working on these fixes and will be monitoring for more data to resolve them.


  • The Behind Enemy Lines ability for the US Airborne does not function as intended. 
  • Some units get stuck when exiting a building depending on surrounding geometry.  
  • Sometimes abilities will overlap existing abilities instead of moving to an empty square in the HUD. This often occurs when upgrading units or unlocking new Veterancy abilities. 


  • Due to the complex nature of the Campaign’s systems, we are expecting some rare edge case issues at launch. We hope to address these in the following weeks after launch. 
  • If you become stuck after capturing Salerno or before completing the "Defend Salerno" objective, reload to a save before you destroy the enemy company nearby. Leave the enemy company alive until the "Defend Salerno" objective begins.
  • When the game updates with a patch, save files made during a Skirmish/Mission may be reset to the beginning of the mission or encounter.
  • Sometimes when attempting to garrison a unit, either in a city or a ship, they are unable to in their current position. Try moving the unit and attempting to garrison again.  
  • Anzio Annie fires at all player squads instead of specific targets. This causes an increased difficulty spike we hope to fix in a later patch. 


  • We found in our last public test that in instances with HMGs, they were taking up most of our sound scape, not allowing other audio files to play. The audio team continues to investigate instances like this to improve our audio quality and accuracy. 


  • If Singleplayer is not available from the Main Menu, please ensure that you are not in a party.
  • Some portraits or icons may appear lower resolution or not scaling correctly to the user interface. These will continue to be updated and addressed in the future.
  • Some portraits are not displaying their updated artwork.
  • Holding the ESC key on cinematics to skip them sometimes displays the Victory screen. 
  • If all game mode buttons in the Main Menu are greyed out, except for Single Player, check your network connection or the Relic Forums for server maintenance.  
  • The pop-up “Cheats Input Prioritized” appears in the top left corner when pressing specific key binds meant for Modding. If the key bind is pressed again, this box will disappear. 


  • To use Ultra Texture settings, you need a GPU with minimum 16 GB of Memory. High will require 8GB of GPU Memory. We are working on lowering the Ultra requirements after launch. 
  • Instability or crashing may occur when switching settings around monitor resolution and windowed mode or when alt-tab/alt-enter during game. We are looking to make improvements in a future patch. 
  • Depending on your GPU, when zooming in and out of the map, base textures might begin to flicker. A fix for this is in progress. 
  • We have enabled scalable ambient occlusion on units and vehicles and improved their blending. We continue to investigate improvements for our visuals based on player feedback.

Modding & Modding Tools

  • The CoH3 modding tools function slightly differently from the CoH2 modding tools. As such, there may be a bit of a learning curve to get used to them and replicate the work modders will have done in past titles.
  • Though players can override many values when it comes to balancing, certain values will not be able to change.
  • The overrides for editing squad, vehicle, and building properties may be limited in certain circumstances as there are certain restrictions on blueprints.
  • To move squads or vehicles, modders will need to either add mission prefabs to spawn them or spawn/move them via the scenario SCAR script associated with a scenario.
  • Pop cap cannot be adjusted with Tuning Packs but can be adjusted via SCAR in Game Modes.
  • Tech trees for Battlegroups currently cannot be changed, though we are investigating potential solutions. However, players can modify many of the aspects and dependencies that make up other tech trees.

MaJ v1.0.0.8713 (alias 1.0.2) - 2023/02/27 lundi

Taille : 187Mo

These GPU crash fixes aim to address the largest portion of our current crash rate and instability. We will be monitoring our crash rate after releasing this patch and determining if we need to rollback. Please report and continue to send us Bugsplats. 

We are targeting another hotfix this week and are still working to confirm those fixes. The 1.0.3 hotfix will include an Audio pass, along with addressing progression blockers and additional crash fixes.   

Note: Mid-mission saves will be invalidated after all patches and hot fixes. Please revert to a previous autosave to continue your progress. We will do our best to minimize the frequency of patches while also providing estimated release dates. 


  • Fixed a rendering issue with shadows flickering causing instability in the GPU
  • Reduced building textures flickering when zooming in & out and moving the camera. 
  • Fixed window sizing crashes on the GPU when using ALT +TAB, ALT + ENTER, and/or minimizing the game.

    • Bonjour,   Sur COH3 j'ai pu  faire plusieurs parties sans problème mais maintenant au bout de quelques secondes l'écran devient noir, on peut voir les unités et le jeux continue. J'ai une carte intel graphique 630 Que faire?
    • Bonjours,  Depuis quelques temps j'ai constaté que certain des mods installés pour COH sur mon pc bug au chargement des maps ou in game et m'affiche un message qui dit "Impossible de créer le rapport d'erreur vérifiez votre dossier TEMP" j'ai essayé une manip expliquée sur un forum de Jeuxvidéo.com mais ça marche pas ! Avez vous une solution fiable ? Je précise qu'il s'agit du Pack comprenant COH, COH : OF, COH : TOV et COH : Legacy et j'ai constaté le bug sur Battle of the Bulge et sur Far East War
    • MaJ v1.4.3.21751  - 2023/12/15 vendredi Taille : 232,4Mo This hot fix addresses our top crash from this past week that was causing players to crash while loading into a multiplayer match. This was especially problematic in larger game modes. We wanted to thank all our players for filling out their BugSplat crash reports so that we could diagnose the problem in a timely fashion. Thank you for all your patience as we worked to resolve this. ELO & ranks are now reenabled as well. Bug Fixes Addressed a crash while loading into a 4v4 quick match. Artillery Radio Beacon now stops receiving bonuses to rate of fire and range as soon as the ability is cancelled. Fixed alignment of territory lines and icons on the tactical map for rectangular shaped maps. Fixed an issue where players could not change Company Support options when starting a mission in the Italian Dynamic Campaign. Fixed some messages not appearing when a tutorial is calling the player's attention to something. Source : https://store.steampowered.com/news/app/1677280/view/3891737145570951427
    • Bonjour, Je pense que la version de CoH sur le CD/DVD de CoH Anthology est en quelque sort trop vieille et donc plus compatible pour fonctionner sur Windows 10. Si je me suis souviens bien, CoH Anthology regroupe : CoH, CoH : Opposing Fronts et CoH : Tales of Valor. As-tu toujours les clés/codes CD de ces jeux ? Si oui, alors je te conseille d'ajouter ces clés sur Steam pour pouvoir télécharger le jeu dans sa dernière version et y jouer. Procédure dans ce sujet :
