BDO Optimizer vs NVIDIA ShadowPlay

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.

NVIDIA ShadowPlay is a free Windows companion app for PC gamers and creators, combining driver updates, game and application optimization, and recording tools in an in-game overlay. Manual recording supports up to 8K HDR at 30 fps or 4K HDR at 120 fps; NVIDIA describes the performance impact as minimal. Automatic Highlights captures key moments, and overlay metrics include FPS, GPU and CPU utilization, FPS 1% Low, and system latency. GeForce RTX 40-series GPU owners can record with AV1 encoding. The app also includes a GPU control center for graphics settings and tuning, Freestyle filters for supported games, and ways to discover and launch selected NVIDIA apps. Requirements include Windows 10 or 11, a GeForce RTX 20, 30, 40, or 50 Series GPU, driver 551.52 or later, 2 GB of system memory, and 600 MB of disk space. Signing in is optional; NVIDIA says login enables users to redeem GPU bundles and rewards.
