The latest AMD Adrenalin driver lets you turn FSR 4 on in a bunch more games but OptiScaler might still come in handy for older titles

It's been about six months since AMD FSR 4 launched and one of the only real problems with it has been uptake. There just haven't been many games that officially support the upscaling and frame gen tech, and enabling it has often required the use of a third-party tool. Now, though, AMD has finally added the ability to enable FSR 4 in a bunch of games by flipping a toggle switch in the latest Adrenalin driver.

The Adrenalin 25.9.1 drivers, AMD explains, enable FSR 4 in over 85 games: "By updating your AMD Software: Adrenalin Edition driver, you automatically unlock access to this cutting-edge technology on your AMD Radeon RX 9000-series graphics card. Simply enable FSR 3.1 within the supported game and ensure the FSR 4 toggle is turned on from the AMD Software: Adrenalin Edition application."
