BDO Optimizer vs DisplayMagician

BDO Optimizer is a free, open-source desktop app for Black Desert Online players who want hardware-aware CPU-affinity recommendations and local frame-rate and frame-pacing checks. It reports CPU topology, cache levels, RAM, GPU and driver details, and local storage. Recommendations can use published guide masks or detected topology, including P-cores for Intel hybrid CPUs, V-Cache CCDs for X3D CPUs, and one CCD for multi-CCD CPUs.

Saved benchmark runs retain raw frame times and calculate average FPS, P1 low, and time-weighted low metrics locally. On Windows with NVIDIA graphics, it can merge-import selected game driver-profile settings and restore the prior profile; Radeon users get manual Adrenalin instructions. It can change specified Black Desert configuration files with backups and one-click restoration. Benchmark sessions remain local and are not uploaded. Hardware inspection works on Windows and Linux and is partial on macOS, but applying and measuring BDO affinity is Windows-only. The BDO workflow needs 64-bit Windows, an installed game copy, bundled PresentMon, and administrator permission for benchmarking. Windows x64 releases are unsigned ZIP files and may trigger SmartScreen.

DisplayMagician applies display and sound setups when a Windows shortcut opens a game or application, and can restore earlier settings after it closes. Users can save display profiles, including wallpapers, and assign audio profiles or devices to shortcuts. Shortcuts can also start or stop helper programs around an application’s launch. Listed launchers include Steam, Ubisoft Uplay, Origin, Epic Games, and GOG.com; shortcuts can be launched from the desktop, notification tray, context menu, hotkey, joystick, or game controller. Display support includes NVIDIA Surround, AMD Eyefinity, Intel Combined Displays, cloned and extended displays, HDR, rotated screens, and refresh rates. USB and wireless display devices are supported, as are SuperDisplay and Spacedesk, including Android tablets used as displays. A field-of-view calculator is included for matching games to a sim-rig layout. DisplayMagician is free and supports per-game profiles and game library scanning. It requires 64-bit Windows 10 version 1809 or later, or 64-bit Windows 11, plus .NET 10.0, included in the installer bundle.
