AMD’s latest Radeon driver update (Adrenalin Edition 25.9.1) is expanding support for FSR 4 upscaling and frame generation. According to the official patch notes, FSR 4 can now be enabled in most DirectX 12 titles that already support FSR 3.1. With the latest update, FSR 4 is now compatible with 85 games in total, however it is still limited to RDNA 4-based Radeon 9000 series GPUs.
In a separate announcement post, AMD has explained how this works and notes that enabling FSR 4 through its new driver update is a pretty seamless process. Once users update to the latest Adrenalin Edition driver, their Radeon RX 9000 Series graphics cards should automatically gain access to FSR 4. Additionally, users need to switch to FSR 3.1 in their supported game settings and then toggle FSR 4 within AMD”s Adrenalin Edition software. This enables the driver to override the in-game FSR 3.1 implementation with the newer FSR 4 version.
