AMD's upcoming FSR 4 upscaling technology could be easier to implement than previously thought, with rumours suggesting a seamless upgrade path for games already supporting FSR 3.1.

This comes from Kepler_L2 (via VideoCardz) who hinted on Twitter that FSR 4 might be a simple drop-in replacement for FSR 3.1 (FSR 3 Frame Gen not included). This means that developers could potentially upgrade their games to FSR 4 with minimal effort, and gamers might even be able to swap DLL files themselves.

This news is particularly exciting given AMD's silence on FSR 4 since its brief showcase at CES 2025. During the event, AMD demonstrated the visual improvements of FSR 4 over FSR 3.1, highlighting its AI-powered upscaling capabilities and significant gains in image quality over the previous version of the technology.

If AMD delivers on this rumoured seamless upgrade path, over 40 games that currently support FSR 3.1 could be ready for FSR 4 at launch. This would significantly boost FSR 4's adoption and allow gamers to experience the benefits of the new technology in a wide range of titles as soon as FSR 4 is available.

KitGuru says: Do you believe FSR 4 will have a chance against DLSS 4 and its new transformer model?
