xOCD 1.4.31 Changelog

Integrated Benchmark

  • Added an integrated DirectX 12 GPU benchmark.
  • Uses one identical fixed native-4K workload on every supported GPU.
  • No GPU-specific multipliers, adaptive quality, resolution scaling or score normalization.
  • xOCD Score is calculated as:
    Average FPS × 100
  • Added graphics, compute, VRAM and thermal validation phases.
  • Added average FPS, 1% low, 0.1% low, frametime, temperature, clock, power and stability results.
  • Benchmark renderer runs in an isolated process so xOCD remains available if an unstable overclock crashes the test.
  • Added Quick, Standard and Extended validation durations.
  • Added Windowed, Borderless and Fullscreen modes.
  • Added configurable thermal safety cutoff.
  • Reports are saved as styled HTML files under:
    %LOCALAPPDATA%\xOCD\BenchmarkReports
  • Added an Open Reports Folder button.
  • Removed the unnecessary workload selector because the benchmark uses one fixed workload.

Adaptive Tuning Lab

  • Promoted Adaptive Benchmark Lab to Adaptive Tuning Lab.
  • Removed the Beta label.
  • Integrated it with the native xOCD benchmark.
  • Automatically establishes a baseline before tuning.
  • Searches core and memory offsets separately.
  • Requires repeated passes before accepting a candidate.
  • Performs final combined stability validation.
  • Rejects candidates after crashes, rendering errors, thermal stops, telemetry loss, consistency loss or performance regression.
  • Added automatic restoration after failed or interrupted tuning.
  • Added an on-disk recovery journal.
  • Accepted results can be saved as GPU/VBIOS-specific profiles.

Full OSD Editor

  • Added a complete Full OSD Editor for the native xOCD overlay.
  • Changes now update the running OSD live.
  • Removed the Save Layout requirement; closing the editor automatically stores the layout.
  • Unchecking an element automatically realigns the remaining fields without leaving blank spaces.
  • Added unlimited telemetry-field selection.
  • Added custom labels, rows, columns, text sizes and colors.
  • Added optional history graphs for individual fields.
  • Added customizable:
    • OSD title
    • {app} application-name placeholder
    • Title visibility
    • Font family
    • Row height
    • Column width
    • Position
    • Scale
    • Resolution-aware scaling
    • Opacity
    • Update interval
    • Text, background and accent colors
  • Added Auto Arrange, Select All and Clear actions.
  • Fixed duplicate-looking overlay elements caused by overlapping saved positions.
  • Fixed native FPS capture disagreeing with the selected game.
  • Reduced OSD CPU usage and redundant redraws.

Profiles and Storage

  • Added per-GPU and per-VBIOS profile storage.
  • Profiles are isolated by GPU UUID and VBIOS version.
  • Added a selectable Main Profile for each GPU/VBIOS.
  • Added automatic Main Profile loading when xOCD starts.
  • Added profile import and export with multi-profile selection.
  • Application profiles now remain suppressed after Reset until the bound application closes.
  • Migrated settings, profiles, reports and overlay layouts from the old synVolt folder to:
    %LOCALAPPDATA%\xOCD
  • xOCD no longer saves new data under the synVolt folder.

V/F Curve Editor

  • Added live V/F curve editing with a short debounce.
  • Every curve write is read back and verified.
  • Failed writes restore the last verified curve.
  • Flatten + Cap now keeps the selected voltage point as the unique highest-frequency point.
  • Higher-voltage points are placed one complete 15 MHz boost bin below the selected knee.
  • Added exact voltage-point locking when supported.
  • Set + Lock, Unlock and Reset now apply immediately.
  • The graph now uses the GPU’s actual voltage nodes.
  • Expanded the visible frequency range to 4000 MHz.

Performance and Reliability

  • Moved GPU setting writes and readback verification off the window thread.
  • Apply, Reset, Boost and V/F lock operations no longer freeze the interface.
  • Moved detailed NVAPI telemetry inventory off the window thread.
  • Reduced redundant gauge and telemetry repaints.
  • Reduced native-overlay redraw overhead.
  • Improved responsiveness while applying overclocks and running benchmarks.
  • Fixed application-profile requests being ignored when telemetry polling was active.
  • Fixed benchmark telemetry appearing frozen during a run.

Interface Improvements

  • Redesigned the Integrated Benchmark results and empty state.
  • Improved benchmark text contrast and readability.
  • Added matching custom xOCD title bars to:
    • Main dashboard
    • Options / Community
    • Full OSD Editor
    • Adaptive Tuning Lab
    • Integrated Benchmark
  • Added working drag, minimize, maximize, restore, close and edge/corner resizing.
  • Fixed Options / Community not being movable.
  • Fixed nothoov & pchoov displaying incorrectly in the title bar.
  • Improved high-DPI and smaller-window layouts.
  • Fixed controls being hidden until a window was manually resized.

Requirements

  • Windows 10 or Windows 11, 64-bit
  • NVIDIA GPU and installed NVIDIA driver
  • Microsoft .NET 10 Desktop Runtime (x64)
