Settings Explained

Access settings via the Settings button in the bottom right of the dashboard, or through the system tray icon right-click menu.

Tab 1: General

Setting	Default	What it does
Start with Windows	On	Adds the app to Windows startup. It will launch automatically and start in your default mode.
Start minimized to tray	Off	When combined with "Start with Windows," the app launches silently in the system tray.
Minimize to tray on close	Off	When off (default), clicking X closes the app completely. When on, clicking X minimizes to the system tray instead.
Show notifications	On	Enables Windows notification toasts for events like game detection.
Default mode on launch	Monitor	Which mode the app starts in. Choose Monitor or Optimize. Set to Optimize if you want automatic optimization from the moment the app launches.
Optimization strategy	Driver Preference or Affinity Pinning	Choose between Affinity Pinning (direct CCD assignment via SetProcessAffinityMask) or Driver Preference (AMD V-Cache registry key). On first run for Dual-CCD X3D processors, defaults to Driver Preference when the AMD V-Cache driver is detected; falls back to Affinity Pinning otherwise. For standard (non-X3D) dual-CCD processors, Affinity Pinning is the default since the V-Cache driver is not applicable. Strategy selection is tier-gated. See AMD V-Cache Driver Preference for details.
Polling interval	2000ms	How often the app checks for running processes. The app uses adaptive polling: 4 seconds when idle, 2 seconds when a game is detected (active mode). This setting controls the base interval. Range: 1000ms-5000ms.
Dashboard refresh	1000ms	How often the dashboard heatmap and UI updates. Lower values give smoother animations. Range: 500ms-5000ms.

Tab 2: Process Rules

This tab has two columns:

• Games column (left): Processes to pin to the V-Cache CCD (CCD0). Includes autocomplete from scanned library results. Add or remove entries. Manual entry supported.
• Background column (right): Processes to pin to the Frequency CCD (CCD1). Includes a process picker for selecting from currently running apps. Add or remove entries. Manual entry supported.

See the dedicated Process Rules page for full documentation.

Tab 3: Detection

Setting	Default	What it does
Enable GPU auto-detection	On	Automatically detect games by monitoring GPU usage. When disabled, only manual rules and library scan matches are used.
Require foreground window	On	Only detect a game via GPU heuristic if it's the active foreground window. Prevents background GPU processes (video encoding, etc.) from being misidentified as games.
GPU usage threshold	50%	Minimum GPU 3D engine usage a process must show before it's considered a game candidate. Higher values reduce false positives but may miss lighter games. Range: 20%-90%.
Detection delay	5s	How long a process must continuously exceed the GPU threshold before being confirmed as a game. Prevents brief GPU spikes from triggering false detections. Range: 1s-15s.
Exit delay	10s	How long to wait after GPU usage drops below threshold before declaring an auto-detected game has exited. Prevents brief dips (loading screens, cutscenes) from causing premature exit detection. Range: 5s-30s.
Excluded processes	(list)	Processes that should never be detected as games, even if they exceed the GPU threshold. Default list includes browsers, media players, and development tools.
Rescan Game Libraries	(button)	Triggers a manual rescan of all detected game libraries (Steam, Epic Games Store, GOG Galaxy). Use this after installing new games or if the Game Library tab is missing titles.
Download Game Artwork	Off	When enabled, downloads box art images for games in the Game Library tab. Connects only to Steam's public CDN for artwork. No data is sent. Off by default for privacy.

Adaptive Polling

The app uses adaptive polling intervals for process scanning:

• Idle (no game detected): 4-second polling interval
• Active (game detected): 2-second polling interval
• The app automatically switches between idle and active polling when a game is detected or exits
• Re-migration of newly launched processes during active mode occurs within 5 seconds

Tab 4: Overlay

Setting	Default	What it does
Enable overlay	Off	Show the compact always-on-top overlay window. Can also be toggled with Ctrl+Shift+O.
Show CCD load bars	On	Display CCD usage bars in the overlay showing average load per CCD.
Opacity	80%	Overlay transparency. Lower values make it more see-through. Range: 30%-100%.
Auto-hide after	10s	Seconds of inactivity before the overlay fades out. It reappears when a new event occurs. Range: 5s-30s.
Pixel shift every	3 min	How often the overlay shifts position by a few pixels to prevent OLED burn-in. Range: 1-10 minutes.
Default position	Top Right	Which corner of the screen the overlay appears in when not manually dragged to a custom position.
Hotkey	Ctrl+Shift+O	Toggle overlay visibility from anywhere, including while in-game.

Tab 5: Advanced

Setting	Default	What it does
Log level	Information	Controls verbosity of the log file at %AppData%\X3DCCDOptimizer\logs\. Options typically include Debug, Information, Warning, Error.
Open Log folder	(button)	Opens the log directory in Windows Explorer for easy access to log files.
Open Config folder	(button)	Opens the config directory in Windows Explorer.
Reset all settings	(button)	Restores every setting to its default value. Requires confirmation.

Settings File Location

Settings are saved as JSON at %AppData%\X3DCCDOptimizer\config.json. You can back up or transfer this file between machines.
