Update 9.15.1: Technical Aspects

Version 9.15.1 slightly differs from the World of Tanks updates players are used to: the importance of the technical part of this patch prevails over the game content visible to players. The most important technical feature will be the transferring of the game’s battle interface to the latest version of the ActionScript 3.0 programming language. In this article, we will explain the purpose of this change, what the advantages of ActionScript 3.0 are, and how to avoid any inconveniences after the update’s release.

Why do we need the new version of ActionScript 3.0

ActionScript 2.0 was used for interface-development solutions at the time of the game’s release. In 2015, the World of Tanks Garage was transferred to ActionScript 3.0, and with Version 9.15.1, the game’s battle interface will be fully transferred into this new version. In general, after transferring to the new platform, the performance of the client in version 9.15.1 will remain the same or will slightly improve. However, transferring to ActionScript 3.0 provides new opportunities to optimise the game client. Also, the process of creating modifications will be more convenient, as there will be more opportunities for mod makers to use AutoDesk Scaleform.

Game client performance modifications

When developing a new platform for the battle interface, Wargaming worked closely with the most popular mod makers. Thanks to the work done previously, we were able to significantly reduce the performance risks of third-party client modifications.

Important! It is not recommended to install mods from a previous version of World of Tanks, or move mods from a previous version to the 9.15.1 folder, as it may lead to the game being unstable.

Despite close cooperation between the World of Tanks development team and mod makers, unfortunately some modifications may potentially be unavailable for some time, as their installation might lead to technical problems. For this reason, it is not recommended to install the following mods to the game client:


  • All components


  • Deluxe damage panel (custom damage panel)
  • Chat with message history
  • Tank icons

Problem using modifications

There are many players who play using different client modifications. We remind you that these modifications are not created by Wargaming, but by third-party developers and users. So, with the release of official World of Tanks updates, issues can occur with your game client due to these modified files: things such as decreased game performance, freezes, crashes, missing textures and other problems. In most cases, such problems are solved by deleting the game modification – however, sometimes a complete clean reinstall of the game is needed.

Important: Wargaming is not responsible for game-client issues due to modified files.

We remind you that since the release of version 9.12, it is possible to turn game modifications on and off. If you have any problems, try to run the game in safe mode:

  • Run the launcher
  • Click the arrow near the “PLAY” button
  • Choose β€œLaunch the game in safe mode”

    1. No for a lot of mod users – if you would take a look at forums, you’d see many tards screming “stupid WG another new patch and more bugs, my game is crashing fuck WG” (usually with terrible grammar, and who would’ve though, lots of them are <50% and majority are <53%), when people advise them to delete mods, 90%+ of problems are solved.


        1. Having 53% winrate doesn’t make you a retard, but blaming WG for releasing bad update while you installed mods that cause your game crash is. I’m just sayin’, majority of people complaining are also bad to mediocre at this game.

          Almost like there is a connection between winrate and intelligence of people

  1. I hope the xvm mod will be disabled for a week until the devs fix it. It would mean a lot of nice random battles! Let’s pray!


    1. I hope that this happen ppl that try to use XVM even when WG did it would not work.

      “…sometimes a complete clean reinstall of the game is needed.”

      And of course 1 week without XVM cancer is gold =P


  2. WTF is wrong with WG, the mods is the only thing that make wot worth the time to play, vanilla wot sucks worse that a 16 bit 80’s game and if the mods can’t be fixed people will quit playing.

  4. It’s seems like WG didn’t understand when ppl siad vanilla 9.15 is crashing in the middle of every single game. Pathethic memory adressing and leaks? Nah everything is fine we are great devs, masters of optimization. Game utilize max 970MB of GPU memory, but ingame folks see low memory warnings on textures, fps drops and crashes…Hell, they for sure use some mods and only lie that they don’t…so lets kill all the mods, becouse all of this hate is becouse of mods. Let’s buy premiumπŸ™‚

    I don’t think WG can figure how to make it work, WG keeps breaking more with every update. I think they need to hire some developers over at AW to bail them out.


  6. It seems WG (wot) assume we are all Chimpanzees. They rape our wallets and drink champagne. WG…. if you hire monkeys to write your software, you are only going to have a crap game. We (the chimps) pay your fat salary’s. So GET A GRIP and SORT THE FUCKER OUT.
