Introduction of FSR 4 and New Game Support
AMD has officially launched its Adrenalin 25.9.1 WHQL drivers, which introduce significant enhancements for users of Radeon graphics cards. This update adds support for FidelityFX Super Resolution 4 (FSR 4) in nearly 100 games, particularly benefiting those using RDNA 4 (Radeon RX 9000 series) GPUs. Notable new titles supported include *Borderlands 4* and *Hell Is Us*, both of which are optimized for this latest driver.
Key Features and Improvements
The Adrenalin 25.9.1 driver allows FSR 4 to be enabled in most games that already support FSR 3.1 and utilize DirectX 12. This marks a shift from previous reliance on third-party tools for enabling FSR 4, streamlining the process for gamers. The driver also addresses various issues, including screen corruption in *Mafia: The Old Country* on Radeon RX 6600 series graphics products and stability problems in *WUCHANG: Fallen Feathers* when FSR 4 is enabled on RX 9000 series GPUs.
Known Issues and Ongoing Challenges
Despite the improvements, the driver is not without its challenges. Users may still encounter intermittent crashes while playing *The Last of Us Part II* on RX 7900 series graphics, as well as issues in *Call of Duty: Black Ops 6* and *NBA 2K25* on RX 9000 and RX 9070 series GPUs, respectively. Additionally, some users have reported stuttering when using VR headsets at refresh rates of 80Hz or 90Hz on RX 7000 series graphics products. AMD has acknowledged these ongoing issues and is actively working on resolutions.
Official Statements & Responses
AMD has emphasized the importance of this driver update, stating that it significantly enhances gaming performance and visual quality for users. The company has also communicated its commitment to resolving the remaining issues, indicating that fixes are forthcoming in future updates.
Criticism & Opposition
While the update has been generally well-received, some users have expressed frustration regarding the persistence of known issues, particularly with high-profile games. Critics argue that AMD should provide clearer communication about the status of these issues and the timeline for fixes.
