CapFrameX PMC Reader Plugin

The PMC Reader Plugin extends CapFrameX with low-level CPU performance monitoring counters (PMC) by reading Model Specific Registers (MSRs) directly. It exposes CPU cache and memory metrics — such as L3 cache hit rates, DRAM bandwidth, and DRAM latency — that are not accessible through standard OS APIs.

Installation

1. Download CapFrameX.PmcReader.Plugin.dll from the release assets
2. Copy the DLL into your CapFrameX installation folder
   Default path: C:\Program Files (x86)\CapFrameX
3. Restart CapFrameX — the plugin sensors will appear automatically

⚠️ Important

This plugin uses the WinRing0 kernel driver to access CPU MSRs. WinRing0 is blacklisted by Microsoft Windows Defender and may be flagged or blocked.

In the worst case, you may need to disable Windows Defender real-time protection for the kernel driver to work properly.

Use this plugin at your own risk.

CapFrameX Portable Mode

CapFrameX now supports a portable mode that allows the application to run entirely from a single folder without writing to system directories. This is useful for running from USB drives, network shares, or keeping multiple isolated installations.

How It Works

Portable mode is activated by placing a portable.json file in the same directory as the CapFrameX executable. When the application starts, it checks for this file and redirects all data storage to paths relative to the application directory.

Key Features

• Self-contained: All configuration, captures, screenshots, and logs are stored relative to the application folder
• No registry modifications: The application doesn't write to the Windows registry in portable mode
• No system folder usage: Bypasses %AppData% and Documents folders entirely
• Configurable paths: All storage paths can be customized via portable.json

portable.json Configuration

Create a portable.json file in the CapFrameX application directory with the following structure:

{
  "portable": true,
  "paths": {
    "config": "./Portable/Config",
    "captures": "./Portable/Captures",
    "screenshots": "./Portable/Screenshots",
    "logs": "./Portable/Logs",
    "cloud": "./Portable/Captures/Cloud"
  }
}

Configuration Options

Property	Description	Default
portable	Enables portable mode when true	true
paths.config	Configuration files (AppSettings.json, overlay configs, sensor config, UI state)	./Portable/Config
paths.captures	Capture recordings	./Portable/Captures
paths.screenshots	Screenshot storage	./Portable/Screenshots
paths.logs	Log files	./Portable/Logs
paths.cloud	Cloud download directory	./Portable/Captures/Cloud

All paths are relative to the application directory. You can use ./ or .\ prefix, or just the folder name.

Requirements

When running in portable mode, the following dependencies must be installed on the system:

• .NET 9.0 Desktop Runtime (x64) - Download
• Visual C++ 2015-2022 Redistributable (x64) - Download

The application will check for these dependencies on startup and display a message if any are missing.

Creating a Portable Distribution

1. Copy the CapFrameX application files to a folder
2. Create a portable.json file with the configuration above
3. (Optional) Pre-create the Portable subdirectory with: Config, Captures, Screenshots, Logs
4. The application is now portable and can be moved to any location

Behavior Differences

Feature	Installed Mode	Portable Mode
Config storage	%AppData%\CapFrameX\Configuration	./Portable/Config
Captures storage	Documents\CapFrameX\Captures	./Portable/Captures
Screenshots	Documents\CapFrameX\Screenshots	./Portable/Screenshots
Logs	%AppData%\CapFrameX\Logs	./Portable/Logs
UI state (window size, column widths)	%LocalAppData%\Jot	./Portable/Config
Window title	"CapFrameX"	"CapFrameX Portable"
Config migration	Migrates old settings	Skipped
Start with Windows	Available	Disabled

Notes

• Settings configured in portable mode are stored in the portable config folder and won't affect or be affected by an installed version
• The portable.json file must be valid JSON; if parsing fails, the application falls back to installed mode
• Directories are automatically created if they don't exist

Troubleshooting & Known Issues

The following tips address the most common issues reported by users and can help resolve stability, overlay, and capture-related problems efficiently. We recommend working through them in order if you encounter unexpected behavior.

1. Ensure you are running the latest version
   If you experience application crashes or unstable behavior, verify that you have installed CapFrameX v1.8.4 or newer. Many known issues have been resolved in this patch. If you were previously using version 1.7.7, we recommend uninstalling CapFrameX before installing the new version.

2. Reset application settings
   In some cases, corrupted or outdated configuration files may cause problems. Deleting
   %appdata%/CapFrameX/Configuration/AppSettings.json
   will reset CapFrameX to its default settings and often resolves startup or UI-related issues.

3. Reset overlay configuration files
   If overlay-related problems persist, try deleting the overlay configuration files located at
   %appdata%/CapFrameX/Configuration/OverlayEntryConfiguration_(0/1/2).json.
   These files will be recreated automatically on the next application start.

4. Restore missing or zero-value overlay entries
   When overlay entries are missing or display constant zero values, open the Overlay tab and use the Reset button to restore all overlay entries to a valid default state.

5. Fix incorrect overlay entry order
   If the order of overlay entries appears inconsistent or unintentionally rearranged, use the Sort button in the Overlay tab to restore a clean and logical ordering.

6. Resolve frametime anomalies after updates
   In rare cases, existing background capture processes can interfere with CapFrameX after an update. If you encounter frametime issues, close all running PresentMon processes before installing or launching CapFrameX v1.8.4 release.

7. Avoid conflicts with other monitoring tools
   Applications such as HWiNFO or AIDA64 that implement their own FPS or frametime metrics may conflict with CapFrameX’s capture service, as they also rely on PresentMon-based mechanisms. Disabling overlapping FPS or frametime monitoring features in those tools is strongly recommended when using CapFrameX.

Known Limitations

• PC latency metric may return invalid values (NaN) under specific conditions.

• Configurable paths: All storage paths can be customized via portable.json

portable.json Configuration

Create a portable.json file in the CapFrameX application directory with the following structure:

{
  "portable": true,
  "paths": {
    "config": "./Portable/Config",
    "captures": "./Portable/Captures",
    "screenshots": "./Portable/Screenshots",
    "logs": "./Portable/Logs",
    "cloud": "./Portable/Captures/Cloud"
  }
}

Configuration Options

Property	Description	Default
portable	Enables portable mode when true	true
paths.config	Configuration files (AppSettings.json, overlay configs, sensor config, UI state)	./Portable/Config
paths.captures	Capture recordings	./Portable/Captures
paths.screenshots	Screenshot storage	./Portable/Screenshots
paths.logs	Log files	./Portable/Logs
paths.cloud	Cloud download directory	./Portable/Captures/Cloud

All paths are relative to the application directory. You can use ./ or .\ prefix, or just the folder name.

Requirements

When running in portable mode, the following dependencies must be installed on the system:

• .NET 9.0 Desktop Runtime (x64) - Download
• Visual C++ 2015-2022 Redistributable (x64) - Download

The application will check for these dependencies on startup and display a message if any are missing.

Creating a Portable Distribution

1. Copy the CapFrameX application files to a folder
2. Create a portable.json file with the configuration above
3. (Optional) Pre-create the Portable subdirectory with: Config, Captures, Screenshots, Logs
4. The application is now portable and can be moved to any location

Behavior Differences

Feature	Installed Mode	Portable Mode
Config storage	%AppData%\CapFrameX\Configuration	./Portable/Config
Captures storage	Documents\CapFrameX\Captures	./Portable/Captures
Screenshots	Documents\CapFrameX\Screenshots	./Portable/Screenshots
Logs	%AppData%\CapFrameX\Logs	./Portable/Logs
UI state (window size, column widths)	%LocalAppData%\Jot	./Portable/Config
Window title	"CapFrameX"	"CapFrameX Portable"
Config migration	Migrates old settings	Skipped
Start with Windows	Available	Disabled

Notes

• Settings configured in portable mode are stored in the portable config folder and won't affect or be affected by an installed version
• The portable.json file must be valid JSON; if parsing fails, the application falls back to installed mode
• Directories are automatically created if they don't exist

Troubleshooting & Known Issues

The following tips address the most common issues reported by users and can help resolve stability, overlay, and capture-related problems efficiently. We recommend working through them in order if you encounter unexpected behavior.

1. Ensure you are running the latest version
   If you experience application crashes or unstable behavior, verify that you have installed CapFrameX v1.7.9 or newer. Many known issues have been resolved in this patch. If you were previously using version 1.7.7, we recommend uninstalling CapFrameX before installing the new version.

2. Reset application settings
   In some cases, corrupted or outdated configuration files may cause problems. Deleting
   %appdata%/CapFrameX/Configuration/AppSettings.json
   will reset CapFrameX to its default settings and often resolves startup or UI-related issues.

3. Reset overlay configuration files
   If overlay-related problems persist, try deleting the overlay configuration files located at
   %appdata%/CapFrameX/Configuration/OverlayEntryConfiguration_(0/1/2).json.
   These files will be recreated automatically on the next application start.

4. Restore missing or zero-value overlay entries
   When overlay entries are missing or display constant zero values, open the Overlay tab and use the Reset button to restore all overlay entries to a valid default state.

5. Fix incorrect overlay entry order
   If the order of overlay entries appears inconsistent or unintentionally rearranged, use the Sort button in the Overlay tab to restore a clean and logical ordering.

6. Resolve frametime anomalies after updates
   In rare cases, existing background capture processes can interfere with CapFrameX after an update. If you encounter frametime issues, close all running PresentMon processes before installing or launching CapFrameX v1.7.9 release or v1.8.0 beta.

7. Avoid conflicts with other monitoring tools
   Applications such as HWiNFO or AIDA64 that implement their own FPS or frametime metrics may conflict with CapFrameX’s capture service, as they also rely on PresentMon-based mechanisms. Disabling overlapping FPS or frametime monitoring features in those tools is strongly recommended when using CapFrameX.

Known Limitations

• PC latency metric may return invalid values (NaN) under specific conditions.

  We have removed the dependency on WinRing0.sys, closing the related security risk.

• PresentMon updated to version 2.4
  The new PresentMon version adds support for Nvidia Multi Frame Generation (x2, x3, x4) when using the MsBetweenDisplayChange option in the settings menu.

What is the difference between MsBetweenDisplayChange and MsBetweenPresents?

• MsBetweenPresents measures the time between present calls from the application. This reflects how often the game submits frames.

• MsBetweenDisplayChange measures the time between actual displayed frames. This includes any generated frames (e.g., from Frame Generation). Because Multi Frame Generation produces additional frames that are not directly presented by the game, only MsBetweenDisplayChange can show the effective frame rate with FG x2, x3, or x4 enabled.
