This isn't just a minor patch; it is a foundational shift for the 2013 shooter. By transitioning to a 64-bit architecture and implementing a DirectX 11 renderer, the developers are finally addressing the technical debt that has limited the game's performance on modern hardware for years. For players, this means significantly faster load times and better stability during those high-intensity wave-based firefights in Washington D.C.
Beyond the engine core, the beta introduces native PS4 controller support and integrates in-game voice chat via Epic Online Services. While the focus is technical, there are some direct gameplay impacts to note. The China Puff 40mm Grenade Launcher is receiving a buff, with its damage increased from 960 to 1000, ensuring it remains a top-tier choice for crowd control during loud heists.
To jump in, you will need to opt-in via the Steam properties menu under the "open_beta Diesel 3.0 Beta" branch. Keep in mind that while this upgrade makes the game run smoother, it may break existing mods until creators have time to update them. If you are looking to secure your presidential pardons with fewer crashes, this is the version you want to be running throughout July.
