The time has come to trial the upgrades coming to PAYDAY 2. The Diesel engine has been restructured, and even though most of the changes are under the hood, it brings along with it a number of technical improvements players have long been asking for. This is a huge change, **there will be bugs and issues** that need addressing. The open beta will be going for the entire month of July to make sure the transition goes smoothly. That being said... ##### Bug Reporting We have created a new forum on the steam discussions called [Open-Beta Bug Reporting](https://steamcommunity.com/app/218620/discussions/33/). Please use it to report issues you may encounter. Before reporting, please make sure that the issue is related to the beta. Any reported bugs that existed prior to the beta will be moved to the regular bug reporting forum. _For more information, head over to the [\ Engine Upgrade Open-Beta](https://steamcommunity.com/app/218620/discussions/33/563661122262030285/) steam post._ ##### How to join the beta - Open your steam library - Right-Click on the game PAYDAY 2 - Select "Properties" from the dropdown - On the left side of the properties panel select "Game Versions & Betas" - Now select the beta branch "**open_beta** Diesel 3.0 Beta" ##### Disclaimer for modded games Mods will likely be broken and for the beta we want to find un-modded issues, we recommend uninstalling all mods for the duration of the beta. Backing up save data is recommended as some mods (like custom weapons) will be removed from your inventory when uninstalling mods. We're working with the modding community to keep old modded file formats compatible with new game versions. --- ##### **PAYDAY 2: 247 Open-Beta Changelog** ##### Download Size: 32 GB ##### Diesel 3.0 - The game is now 64bit! - The game's renderer is now DirectX 11 - New asset bundling system with compression (game is now down to ~32gb!) - Faster load times for SSDs - Completely rewrote the "Epic Online Services" implementation - In-game voice chat has been implemented for "Epic Online Services" matchmaking - Reduced lobby codes to just 6 characters - The "Modern CPU Support" launch option no longer needs to be selected - Better usage of "performance" cores on CPUs that support SMT - Fixed initial resolution setup on first time boot ##### VR - VR and non-VR versions of the game are now one executable file, there should be no interruption caused by this ##### General - The game's language can now be specified with the command line argument -language english/german/french/etc. instead of having to edit context.xml - The "Tag Team" perkdeck ability can now be activated through enemies and has improved hit detection on teammates - Removed a startup video advertising the legacy collection - Fixed Cheater tag not being applied correctly in certain scenarios ##### Masks - Fixed mask clipping on "Joy" and "Jacket" with some masks - Fixed "Dead By Daylight" entitlements on Epic Games platform not awarding when a Nebula account is linked ##### Input - Mouse input in menus is now based off of the actual position of your mouse - The game will no longer "eat" your mouse courser while Alt+Tab'ing out of the game - Fixed the mouse wheel being able to scroll on other monitors while ingame - Added native support for PlayStation 4 controllers - All text boxes now support modern text editing features like Ctrl+Arrows for navigation, Ctrl+Backspace for deletion and more ##### Interface - The "Lobby Code" UI now no longer appears above certain UI elements - Matchmaking distance filters have been updated to Country/Region/Worldwide instead of the older Close/Far/Worldwide options - Added 180Hz frame rate limit option ##### Weapons - Fixed reflections on the "Kunai Knife" melee weapon - Increased the damage on the "China Puff 40mm Grenade Launcher" from 960 to 1000 - Fixed the "Hailstorm Mk 5" set to Volley mode not being able to pierce body armor _[Truncated at 4000 characters — full notes: https://store.steampowered.com/news/app/218620/view/705523947945329160]_
