AMD SDK suggests 4x and 6x frame generation multipliers are in the works — driver-level tweak will let gamers upgrade existing titles to FSR4 ML-based frame generation

AMD’s latest ADLX SDK hints at a driver-level upgrade that could convert FSR3.1 frame generation to FSR4 in supported games.

The SDK also appears to expose ratio controls, suggesting AMD may be preparing 4x and 6x frame-generation options beyond today’s 2x limit.

If confirmed, the change could improve frame-generation quality in existing titles without requiring game-by-game updates.

It would also help AMD narrow the feature gap with rivals like Nvidia DLSS and Intel.
