MSI Afterburner est un logiciel développé par MSI et RivaTurner pour surveiller et overclocker sa carte graphique et faire des tests de performance. Développé en priorité pour les cartes MSI, il fonctionne aussi pour les autres marques mais selon la marque, les options proposées par le logiciel peuvent être différentes. L'application propose une interface graphique très soignée avec un choix de couleurs différentes. Le panneau des courbes graphiques est directement intégré dans le logiciel mais peut être détaché pour avoir un affichage en temps réel dans les jeux. Pour l'overclocking on retrouve l'essentiel sur l'interface principale : modification des fréquences du GPU, de la mémoire vidéo ainsi que des Shaders (nVidia), modification des tensions, de la vitesse de rotation des ventilateurs. Il est possible d'enregistrer jusqu'à 5 profils différents. Les profils peuvent être rapidement appelés par un raccourci clavier quand vous lancez un jeu.

Changements
v 4.6.5.16370
Added NVIDIA GeForce RTX 40x0 series graphics cards support
Added voltage control support for GA103 and GDDR6x based versions of NVIDIA GeForce RTX 3060 Ti
Added AMD RADEON RX 7900 series graphics cards support
Added total board power monitoring support for AMD RADEON RX 7900 series graphics cards
Added some future AMD and NVIDIA GPU PCI DeviceIDs to hardware database
Added Intel Arc GPUs support to hardware monitoring module. Please take a note that Intel Arc GPUs overclocking and tuning is currently not supported due to Intel hardware control API support limitation to x64 applications only
Added experimental support for Intel 13th generation CPUs
Added experimental support for AMD Ryzen 7xxx CPUs
CPU usage data sources in hardware monitoring module have been switched to alternate implementation based on NtQuerySystemInformation(SystemProcessorIdleInformation), because traditional legacy idle time reporting in NtQuerySystemInformation(SystemProcessorPerformanceInformation) is broken in current Windows 11 22H2 builds
Added workaround for broken fixed fan speed programming API (Overdrive 5 compatible fallback path) for old Overdrive 7 GCN GPUs on 22.5.2 and newer AMD drivers
Added config file switch for disabling native reliability voltage control API on NVIDIA GeForce GTX 9x0 series graphics cards and forcing legacy P-state 2.0 voltage control API usage on such hardware. Power users may use this switch to bypass voltage control lock on NVIDIA Maxwell series graphics cards on release 515 and newer drivers families
Improved correction formula parser with data format conversion, rounding and min/max functions support
Added OCMailbox based bus clock frequency monitoring for Skylake and newer Intel CPUs. Unlike traditional legacy timestamp clock based bus clock frequency estimations, OCMailbox provides support for overclocked BCLK monirtoring. Please take a note that access to OCMailbox is blocked by design of OS when HVCI is enabled
Improved SMART.dll monitoring plugin. Added temperature monitoring support for NVMe devices, including the secondary controller temperature for some Samsung NVMe drives
Default clock frequency limit of voltage/frequency curve editor window has been extended to 3.5GHz. Please take a note that you may still customize the limits via config file if necessary
Update server location changed to new URL inside update checking system. Old update server location reached EOL

RivaTuner Statistics Server has been upgraded to v7.3.4:
o New version’s changes list is huge, it includes more than 100 compatibility enhancements, changes and new features. We continue improving OverlayEditor plugin and the most of improvements are related to it, we strongly recommend you to try it if you still use legacy MSI Afterburner’s On-Screen Display output functionality
o New version also includes upgraded DesktopOverlayHost utility, which can be used to display overlay
