- Based on RivaTuner core, Afterburner contains the mix of the most popular and frequently used RivaTuner’s technologies exposed in new simple and effective user interface
- Unified features for both AMD and NVIDIA graphics cards. You no longer need to change your favorite graphics card utility software when migrating from NVIDIA graphics card to AMD and vice versa. Afterburner provides you almost the same functionality for hardware manufactured by both leading GPU vendors and makes migration process really easy. Just keep overclocking and monitoring your GPU like you are used to do, no need to change your preferences and search for other utility after graphics card upgrade!
- User extendable architecture. You may express your creativity and design your own skins for MSI Afterburner, develop external applications interacting with MSI Afterburner (e.g. sidebar gadgets or smartphone applications remotely controlling your hardware), create localization for your native language, use MSI On-Screen Display server to display any custom text directly from your own application and many, many more!
- Basic overclocking and fan control features including full multi-GPU support, independent shader clock adjustment (NVIDIA GeForce 8, 9 and 200 series cards4), overclocking and fan control profiles with hotkey based activation abilities
- Power limit control via AMD PowerTune and NVIDIA GPU Boost technologies
- Desktop and in-game screen capture features support. BMP, PNG and JPG formats are supported
- Realtime desktop and in-game video capture support via Predator™ technology. Uncompressed, high-performance custom RTV1 and native MJPG video encoding, encoding with third-party external VFW compatible codecs (e.g. Lagarith or x264vfw) are supported in conjunction with wide range of additional video capture related options, multisource stereo and multichannel (for Window Vista and newer) audio capture support. The functionality of expensive commercial video capture products is now available to everyone absolutely for free, there is no need to buy dedicated video capture software anymore!
- Advanced fan control. Most of fan control tools allow you to use either fixed manual fan speed mode or default automatic fan speed mode, where the fan speed automation is performed either by dedicated hardware chip or by display driver depending on graphics card model. In addition to these traditional fan control modes Afterburner also provides user defined software automatic fan speed mode allowing you to define your own fan speed curve. New mode combines flexibility of RivaTuner’s fan speed scheduling technology with new and really easy to use graphical interface for visual fan speed curve editing
- Hardware health monitoring features including popular tray icon, Logitech LCD and On-Screen Display monitoring modes and history logging in native RivaTuner hardware monitoring log file format
- Automatic profiles management system allows experienced users to define their own dynamic downclocking rules on the systems with no hardware downclocking support or program different fan control modes for 2D and 3D applications
- Core 5, auxiliary VDDCI/PEXVDD and memory 6 voltage control gives more freedom to hardcore overclockers. Please refer to your retail MSI graphics card box to find MSI Afterburner voltage control compatibility logos

MSI Afterburner Version 2.3.1 (2013/1/23)
- Now MSI Afterburner optionally allows you to detect VRM defaults without rebooting the PC
- Added voltage control support for UEFI GOP BIOS for MSI R7970 Lightning Boost Edition series graphics cards
- Now MSI Afterburner displays the list of assigned global hotkeys in “i” window
- Now MSI Afterburner properties window is resizable to provide compatibility with low-resolution desktops (less than 1280×1024 with 100% DPI)
- Added new “Enable hardware control and monitoring” option to compatibility properties. This option can be useful if you are using MSI Afterburner for framerate monitoring and videocapture only and don’t want to risk suddenly overclocking your PC
- Added NCT7511Y thermal sensors support to provide compatibility with future MSI graphics cards
- Added workaround for possible VID rounding issues for all supported voltage generator models
- Updated Italian localization
- MSI On-Screen Display server has been upgraded to version 4.5.0. New version gives you the following improvements:

• Improved audio mixer architecture provides better extendibility and better audio tracks synchronization when mixing multiple audio tracks in one
• Push-To-Talk audio recording support. Now you can assign a hotkey for each audio stream and record unmuted audio only when the hotkey is pressed
• Updated German localization

MSI Afterburner Version 2.3.0 (2012/11/20)
- Added 9-bit VID support for CHL8318 voltage regulators to bypass 1.6V limit in Extreme versions of MSI Afterburner
- Fixed rounding error in VID generation for offset voltage control mode for CHL8318 voltage generators
- Now it is possible to start MSI Afterburner in limited functionality mode on the systems with no supported AMD or NVIDIA graphics card. This allows you to use hardware independent features like high-performance Predator™ video capture module on any PC, even if it is using integrated Intel graphics
- Added frametime graph to hardware monitoring module. The graph is displaying the maximum frame time on each sampling period and it is useful for detecting microstutters, which are invisible on averaged framerate graph.
- All documentation is now provided in PDF format
- Added unified videomemory usage monitoring implementation for Windows 8
- Removed obsolete GPU type selection settings for some AMD graphics cards
- Removed obsolete shader clock monitoring for NVIDIA Kepler graphics cards
- Improved hardware database format, now custom design MSI graphics cards are calibrated in separate OEM file to minimize the risk of introducing typos in reference design cards definitions when updating the database
- MSI On-Screen Display server has been upgraded to version 4.4.0. New version gives you the following major improvements in Predator™ video capture module:
- Improved RTV1 compression algorithm. New compression approach combines DXTC, RLE and uncompressed data saving algorithms and allows you to increase image quality at the cost of decreasing compression ratio, while keeping extremely fast compression performance. Please take a note that the previous RTV1 compression implementation is equal to the lowest possible 25% image quality/compression ratio balance in new implementation
- Added 64-bit version of RivaTuner Video Codec. Now RTV1 videos are playable and editable in 64-bit applications (e.g. 64-bit Sony Vegas PRO or Adobe Premiere PRO CS6)
- Huffman tables are no longer omitted by MJPG encoder to improve compatibility with applications using limited MJPG decoders (e.g. Sony Vegas PRO)
- Now both 32-bit and 64-bit versions of RivaTuner Video Codec can optionally decode MJPG videos. Third party MJPG codec installation is no longer required to play or edit MJPG videos with omitted Huffman tables in some applications with limited MJPG decoding support (e.g. Sony Vegas PRO). MJPG decoder can be enabled in video capture compatibility properties
- Multisource audio recording. Now it is possible to record audio from two independent audio sources (e.g. game audio and microphone sound) in two independent audio tracks then mix them later in video editing application (e.g. Sony Vegas PRO) or optionally mix multiple tracks in realtime during capture
- Now it is possible to downmix multichannel audio to stereo in stereo rip and stereo mix modes. Previously available stereo rip mode simply rips front left and right audio channels from multichannel audio stream, whilst new stereo mix mode merges audio from front left, right, center and surround channels
- WASAPI audio packets with timestamp error are no longer included into output audio stream
- External VFW codecs support. Now in addition to built-in uncompressed, RTV1 and MJPG encoders it is also possible to encode video using external VFW codecs installed in the system. It is recommended to download, install and use Lagarith Lossless Codec for lossless video capturing or x264vfw codec for the maximum compression ratio, MSI Afterburner was developed to provide the best compatibility with these codecs
- Video stream synchronization is now based on inserting NULL frames instead of indexing existing frames
- Frame dropping implementation has been improved to provide compatibility with external VFW codecs using temporal compression and deltaframes
- Now output video dimensions are always cropped to be multiples of 2 to provide compatibility with external VFW codecs
- Now framerate is calculated on each frame with sliding 1000ms window approach instead of calculating it once per second
- Improved rendering pipeline flushing implementation for Direct3D9 applications provides more stable framerate when capturing videos with VSync enabled
- New dynamic Direct3D rendering pipeline flushing approach can decrease videocapture related performance hit when capturing videos in Direct3D applications with high rendering framerates
- Added On-Screen Display support for Direct3D 10 applications in Windows 8
- Added German localization
- Updated profiles list
