dsh-perf-hud

A transparent, draggable performance HUD for the DeepSeek Harness web UI: CPU / GPU / memory usage, plus the CPU package temperature when the optional helper is installed.

Highlights

• Fully transparent — no card background, no border. Just three rows of text floating over the interface, with a soft halo so it stays readable on any content.
• Drag it anywhere. On release it anchors to the nearest window corner, so maximising, restoring or resizing the window keeps it exactly where you put it. Double-click resets to the top-right, arrow keys nudge it, and the chevron that appears on hover collapses it to a single row.
• Load-aware colours — usage turns amber at 70% and red at 90%; temperature at 78 °C / 88 °C. Stale readings dim the whole card instead of flashing a fake zero.
• Theme-aware — only --dsw-alias-* tokens, so it follows light, dark and any custom theme.
• Local only — the metrics route answers loopback, same-origin requests and returns 403 for everything else. Nothing is uploaded.

Requirements

• Windows 10/11. The GPU counters, the PowerShell worker and the temperature helper are Windows-specific.
• DeepSeek Harness with the web UI.

Install

From the Plugins page (install from GitHub or a local folder), or:

dsh plugin add ChendarCe/dsh-perf-hud

Then reload the interface once.

What it reads

Metric	Source
CPU usage	node:os CPU-time deltas, once a second
Memory usage	os.totalmem() / os.freemem() — same definition as Task Manager's "In use"
GPU usage	Windows GPU Engine performance counters, busiest engine (what Task Manager reports)
CPU temperature	optional helper — LibreHardwareMonitor's CPU Package sensor
GPU temperature	only when the GPU exposes a temperature sensor; most integrated GPUs do not, so the cell shows —

Temperatures (optional)

The plugin works out of the box; without the helper both temperature cells show —. For the real CPU package temperature, run once (it asks for administrator rights):

helper\setup.cmd

That script downloads and sets up:

• LibreHardwareMonitor 0.9.6 (portable, library only) — reads the sensors;
• PawnIO 2.2.0, a signed kernel driver — required to read MSRs while Windows "Memory integrity" (HVCI) stays enabled, so you do not have to weaken that setting;
• sensor-helper.ps1, which writes one small JSON file about every 0.4 s;
• a scheduled task DSH Perf Sensor (at logon, highest privileges, no window), so it never asks again.

Files go to D:\DSHTools when that drive exists, otherwise %LOCALAPPDATA%\DSHTools. The plugin reads either location.

Measured overhead on an 8-core laptop: 0.08 % of one core and ~87 MB of RAM for the helper — it is mostly waiting on the driver, not burning CPU.

Remove it again with:

helper\uninstall.ps1              # stops the task, uninstalls the driver
helper\uninstall.ps1 -RemoveFiles # ...and deletes the helper files

Limitations

• Windows only.
• GPU temperatures need a dedicated sensor; Intel integrated GPUs do not expose one, and the CPU package temperature is the closest reference (same die).
• The card floats inside the Harness window, not as a separate always-on-top desktop window.

中文说明

DeepSeek Harness 界面里的一块完全透明的性能读数：CPU / GPU / 内存占用率，加上 CPU 封装温度。没有底色和边框，只有三行文字浮在界面上。

• 拖动卡片任意位置移动，松手后吸附到最近的窗口角，窗口最大化 / 还原 / 改变 大小都保持位置；双击回到右上角，方向键微调，悬停右侧箭头可收起成一行。
• 占用率 ≥70% 变琥珀、≥90% 变红；温度 ≥78 °C / ≥88 °C 同理；读数过期整卡变暗。
• 安装：插件页面安装本仓库，或 dsh plugin add ChendarCe/dsh-perf-hud。
• 温度需要可选助手：管理员运行一次 helper\setup.cmd（会安装 LibreHardwareMonitor 与 PawnIO 签名驱动，并注册开机自启任务）。不需要时用 helper\uninstall.ps1 移除。
• 没有温度助手时温度一栏显示 —；Intel 核显本身没有独立温度传感器，同样显示 —。
• 仅支持 Windows；悬浮窗在 Harness 窗口内部，不是独立的桌面置顶窗口。
