DayZ-Legacy-Launcher

A launcher and updater tool for the DayZ Legacy client.

Forked from CPPGameLauncher https://github.com/FLWL/CPPGameLauncher

Launcher Guide

When you first start the launcher you will be prompted to configure your game settings. Here is a detailed explanation of what each setting does, and the recommended configuration.

• Game Platform: Select between DirectX 9, DirectX 11, and Vulkan. (recommended selection: DirectX 11)

  • DirectX 9:
    • The default vanilla renderer from pre-alpha DayZ.
    • Very, very slow performance. Abysmal framerates.
    • Most visually accurate to pre-alpha DayZ in terms of lighting, shading, and object/UI rendering.
    • Great compatibility with a massive range of hardware. DirectX 9 runs on almost any GPU made within the last 15 years.
    • This build is not recommended for use at all and is only provided as a fallback in case of hardware incompatibility.
  • DirectX 11:
    • Our custom renderer solution for DayZ Legacy.
    • Performs up to 80% better than the DirectX 9 client and has a much higher average FPS value.
    • Built with higher-end machines in mind, better hardware utilization.
    • You may notice small or large changes in lighting, shading, or object/UI rendering and potentially exclusive issues like artifacting, visual inconsistencies, or crashes.
    • Seriously, can't stress enough how much better this renderer is in terms of performance.
    • This build is recommended for all users by the DayZ Legacy team and is set as the current default.
    • Good support for a wide range of hardware.
    • The requirements for DirectX 11 are as follows:
      • NVIDIA: Fermi-series GPU (GTX 470) or later required.
      • AMD: Radeon HD 5450 or later required.
      • Intel: Intel HD Graphics 4000 or later required.
  • Vulkan (DXVK):
    • A "best-of-both-worlds" solution between DirectX 9 and DirectX 11.
    • Performs up to 60% better than the DirectX 9 client and has a higher average FPS value.
    • Uses the DXVK translation layer to render the default Direct3D 9 scene on top of a Vulkan device. More info: https://github.com/doitsujin/dxvk
    • Maintains the same visuals as DirectX 9.
    • May have very small and minor visual inconsistencies.
    • Not compatible with older hardware and GPUs.
    • This build is recommended if you are okay with a slightly lower framerate in exchange for more accurate visuals.
    • According to sources from Khronos, NVIDIA, and AMD, the requirements for Vulkan are as follows:
      • NVIDIA: Kepler (600-series) GPU or later required. The GTX 750 and 750 Ti are not supported.
      • AMD: Radeon HD 7000 series or later required.
      • Intel: Skylake CPU or later required. You must be running driver version 15.45.14.4590 or later.

• Game Platform: Select between 32-bit and 64-bit. (recommended selection: 32-bit)

  • 32-bit:
    • This was the default client provided until pre-alpha 0.62.
    • The most stable platform for DayZ Legacy.
    • Subject to standard 32-bit memory and performance limitations.
    • This build is "Large Address Aware", meaning the engine can use up to 4GB of RAM, v.s. the default 2GB.
    • This platform is recommended for all users by the DayZ Legacy Dev team and is set as the current default.
    • Caveat: You'll still be stuck at 2GB if your system is 32-bit, but any processor made in the past 15 years is going to be 64-bit, so this is a very rare situation.
  • 64-bit:
    • An enhanced, custom-developed client from the DayZ Legacy Dev team.
    • A more unstable platform with limited performance advantages.
    • Can improve performance and loading times in specific situations
    • This build has many crashes, instability, and performance issues we are actively investigating and fixing.
    • Your mileage may vary on this platform and nothing is guaranteed.

• Display Mode: Select between Windowed and Fullscreen (Exclusive) (recommended selection: Fullscreen (Exclusive))

  • Windowed:
    • The game runs in a resizable window. Better for multi-monitor users until proper multi-monitor support is added. This can sometimes mess up your graphics settings.
    • Caveat: Moving from windowed mode to fullscreen or vice versa may crash the game.
  • Fullscreen (Exclusive):
    • The game runs in an exclusive full-screen window. Better for single monitor users.

• Memory Allocator: Select between System and Community Memory Allocator (recommended selection: System)

  • System:
    • Allows the OS to manage the game's memory.
    • Good compatibility and performance.
  • Community Memory Allocator:
    • An open-source memory allocator used primarily in ARMA 3 to increase performance.
    • Also known as xtbbmallloc.
    • Can sometimes increase performance and reduce memory usage.
    • YMMV.
