Cutting corners: AMD might have a clever solution to rapidly roll out their upcoming FSR4 upscaling technology to a wide range of games. According to a reliable tipster, the company could provide a straightforward "drop-in" upgrade path from FSR 3.1 to FSR4 for games already implementing the current version. The concept is straightforward: instead of requiring game developers to integrate an entirely new version of FSR, AMD could replace the backend FSR library file. This would allow any game already supporting FSR 3.1 to seamlessly benefit from FSR4's enhanced upscaling quality with minimal effort from developers.The report comes from Kepler_L2, who shared the details in response to a VideoCardz post on X.As of now, AMD hasn't confirmed any details regarding an upgrade path for FSR4. The company only briefly showcased FSR4 at CES, where it was presented as a clear visual improvement over FSR 3.1.If this rumored upgrade plan proves accurate, we could see over 40 existing FSR 3.1-compatible games upgraded to FSR4 immediately upon launch. AMD currently lists over 100 games with existing or upcoming support for FSR 3/3.1, which could provide a strong foundation for the rollout. // Related StoriesHowever, there's a catch. Kepler_L2 notes that FSR 3 compatibility alone may not be sufficient and that only games using FSR 3.1 would qualify for the seamless upgrade. This requirement is likely due to FSR 3.1 being the first version where upscaling and frame generation libraries were separated, simplifying integration. As a result, some games may need to be updated to FSR 3.1 before they can take advantage of FSR4.In terms of improvements, AMD's CES demo showcased FSR4 delivering superior 4K upscaling quality compared to FSR 3.1. The new AI-powered upscaler will leverage dedicated AI acceleration hardware found in RDNA4 GPUs. FSR4 is also expected to offer enhanced frame generation for better performance and a revamped "Anti-Lag 2" feature designed to minimize latency.That said, FSR4's benefits come with a significant caveat: it will initially be exclusive to AMD's next-generation Radeon RX 9070 GPU, part of the RDNA4 lineup. Despite this limitation, an easy upgrade path for the existing library of FSR-compatible games would provide a strong launchpad for the new technology.For now, it remains to be seen whether AMD will pursue this rumored strategy.
