AMD’s latest Adrenalin 26.3.1 driver update has triggered a significant performance regression for many users, with reports indicating that frame rates in supported games have dropped by as much as half.
The issue, first documented by users on community forums and later confirmed by independent testing, appears to affect a broad range of titles utilizing DirectX 11 and DirectX 12 APIs. Users have reported consistent FPS reductions across popular games such as Cyberpunk 2077, Fortnite, and Valorant, with some noting frame rates falling from 60 FPS to 30 FPS or lower on mid-to-high-end Radeon RX 6000 and RX 7000 series graphics cards.
AMD has acknowledged the problem in an official statement, confirming that a bug introduced in the Adrenalin 26.3.1 release is responsible for the unexpected performance degradation. The company stated that its engineering team is actively investigating the root cause and working on a fix, though no timeline for a patch has been provided as of yet.
The driver update, released in late March 2024, was intended to deliver stability improvements and minor feature enhancements for AMD’s Radeon software suite. Instead, it has inadvertently introduced a critical flaw impacting core rendering pipelines, particularly in scenarios involving shader compilation and memory bandwidth allocation.
Industry observers note that such regressions, even as uncommon in major driver releases, can significantly undermine user confidence—especially among competitive gamers and content creators who rely on consistent performance. The incident underscores the delicate balance between introducing recent optimizations and maintaining backward compatibility in complex graphics driver ecosystems.
AMD advises affected users to roll back to the previous stable version, Adrenalin 26.2.2, via the Radeon Software interface until a corrected build is made available. The company has not yet released a hotfix but encourages users to monitor its official support channels for updates.
