Visor

Gaming optimization center for Windows.
Per-game display profiles, PC and network diagnostics, reversible tweaks and FPS monitoring —
honest about what each setting really does, with one-click undo for every change.

Formerly Display Profile Manager. Same app, new name and a lot more inside. Installing Visor offers to remove the old version; your profiles and settings are carried over automatically.

Download

Get the latest build from Releases:

File	What it is
Visor-Setup.exe	Recommended. Per-user installer: no admin rights, nothing else to install. Start Menu shortcut + Apps & Features entry.
Visor-<version>-portable.zip	Portable build. Unzip anywhere and run Visor.exe.
SHA256SUMS.txt	Checksums to verify the downloads.

Windows 10/11 x64. Both builds are self-contained (.NET included). The builds aren't code-signed yet, so SmartScreen may show "Windows protected your PC" — click More info → Run anyway.

What Visor does

Section	What you get
Home	One dashboard: active game session, CPU / GPU / RAM / storage at a glance, health (temperatures, stability, drivers), network status, top suggestions.
My PC	Hardware inventory and live sensors: CPU load, RAM, GPU temperature / load / clocks / throttling (NVIDIA), disks with SMART health, crash and hardware-error events from the Windows log.
Games	Per-game profiles: resolution, refresh rate, power plan, color, FPS cap, companions. Applied when the game starts, restored when it exits. Hotkey color presets, pack gallery, Steam launch.
Optimize	Split into Overview · System · Graphics · Input · Network · Startup · Cleanup. Game Mode, Xbox Game Bar background capture, mouse acceleration, fullscreen optimizations per game, Ultimate Performance plan, hardware-accelerated GPU scheduling, startup apps manager, shader/temp cache cleanup — each with why / risk / how to undo.
Network	Split into Overview · Diagnostics · DNS · TCP. Live throughput, Wi-Fi signal, continuous ping with p50/p95/jitter/loss, traceroute, one-click Diagnose that explains where the problem starts (Wi-Fi, LAN, ISP, DNS), report export. DNS speed test across Cloudflare / Google / Quad9 / AdGuard / OpenDNS / custom with apply & undo, DNS cache flush, Nagle, network throttling, TCP auto-tuning.
Monitor	FPS, frame time, 1 % / 0.1 % lows, p99, stutters and a likely GPU / CPU / capped estimate from Visor's built-in frame capture (Windows ETW events — nothing to download); optional FPS overlay on the game's monitor.
Settings	Defaults, app hotkeys, history, log, themes (dark / light / custom), English / Russian.

Also: tray mode, in-game overlay with live color controls, center zoom (Windows Magnifier), command palette (Ctrl+K), section shortcuts (Ctrl+1…7), emergency display reset.

Honest by design

• No fake boosts. Visor never promises "+30 % FPS". Suggestions come from measured facts (GPU throttling reported by the driver, disk space, startup items, event-log errors) and show the evidence.
• Plain-language trade-offs. Faster DNS speeds up finding servers and launchers — it doesn't lower in-game ping. Turning off Nagle helps only TCP-based games (MMOs); most shooters use UDP. Network throttling matters mainly when music or a stream plays during the game. Visor says so on every card.
• Measure, don't guess. Use Monitor (built-in frame capture) to compare FPS and frame times before and after a change.
• Unavailable means unavailable. CPU temperature needs a kernel driver, which Visor doesn't ship — it shows "n/a" instead of a made-up number.

---

Safety

• Every Windows change can be undone. Visor journals the exact previous value (including "this value didn't exist") and restores it — and warns you if something else changed the setting in between.
• Visor never runs as administrator. Changes that need admin rights (DNS, TCP, HKLM, HAGS) go through a tiny elevated helper: one UAC prompt per change, and it only accepts a fixed allowlist of operations.
• No debloat, no registry "cleaning", no disabling services, no killing processes. Startup apps are disabled (like Task Manager does), never deleted. Cache cleanup shows sizes first and asks before deleting.
• Games are left alone. Visor never touches game memory or files and never injects into a game. It changes only system and driver settings. In-game hotkeys use standard low-level keyboard/mouse hooks inside Visor's own process (like Discord or OBS). FPS capture reads Windows' own frame events (ETW) through a small helper built into Visor.exe — no hooks into the game, no injection, no external tool. Still, follow your game's rules.
• No telemetry, no accounts, no cloud. Network probes run only when you click.

FPS monitoring

The frame capture is part of Visor — there is nothing to download or install. A real-time ETW session needs administrator rights, so pressing Start capture shows one UAC prompt and starts a small helper (Visor.exe --frame-capture); Visor itself stays unelevated. Stop needs no second prompt, and the helper also ends on its own when the game or Visor exits, or after an hour.

Measured: FPS, frame time (present-to-present), 1 % / 0.1 % lows, p99, stutters, and a likely GPU-bound / CPU-bound / capped label with the numbers behind it (GPU load is read on NVIDIA only for now). Not measured yet: displayed vs dropped frames, display latency and click-to-photon. Details: docs/MONITOR-NATIVE.md.

How a game session works

  game.exe starts  ->  matching profile  ->  snapshot desktop state  ->  apply resolution / power / color / extras
                                                                                       |
  game.exe exits   <-------------------------------------------------------------------+
                   restore exactly what the profile changed (also after a crash or sign-out)

1. Add or scan your games in Games (Steam, Epic and other libraries are detected).
2. Tune color, presets and session options per game.
3. Leave Visor in the tray. Autostart is optional.
4. Play — profiles apply and restore on their own.

Where your data lives

Path	Purpose
%LocalAppData%\Programs\Visor\	Default install folder (Visor.exe, Assets\, Uninstall.exe)
%AppData%\Visor\profiles.json	Profiles and settings (.bak = last known-good copy)
%AppData%\Visor\active-session.json	Desktop state captured at game start; deleted after a successful restore
%AppData%\Visor\safeactions.json	Undo journal for Optimize / Network tweaks
%AppData%\Visor\history.json	Recent activity
%AppData%\Visor\ui-state.json	Window position and other UI state
%AppData%\Visor\Visor.log	App log (rotated at 2 MB, user paths masked)

Upgrading from Display Profile Manager imports %AppData%\DisplayProfileManager\ on first start; the old folder is never deleted.

Installer

• Per-user, no UAC. A custom folder always gets a Visor subfolder.
• Safe updates: Visor is closed first (after asking), files are staged and swapped, and a failed update rolls back. Uninstall removes only the files listed in .visor-install.json.
• Silent: Visor-Setup.exe /silent [/dir="D:\Apps"] · "%LocalAppData%\Programs\Visor\Uninstall.exe" /uninstall /silent
• Exit codes: 0 success, 1 failure, 2 nothing to uninstall.

Build from source

git clone https://github.com/Naki-404/DisplayProfileManager.git
cd DisplayProfileManager
dotnet build .\Visor.sln -c Release
dotnet test .\Visor.sln

Tests never change display, power, registry or network settings; they write only to temp folders. Release artifacts (tests run first):

powershell -ExecutionPolicy Bypass -File .\build-release.ps1
