Microsoft’s DirectSR upscaling API supports AMD’s FidelityFX Super Resolution (FSR) 3.1. Microsoft’s DirectSR tool, an API for game developers to program support for all three significant graphics upscaling techs in games, will make it easier for games to support FSR 3.1 in addition to the other upscaling modes.
DirectSR is an API for DirectX12 games that allows game developers to enable support for multiple upscaling tools with a single code path. AMD’s FSR 3.1, Nvidia’s DLSS, and Intel’s XeSS often see mutual exclusivity in video game releases because coding support for all three upscaling solutions is an undue time expense. DirectSR effectively unifies the three solutions, allowing developers to support all three upscalers with a single API.
So far, only 43 games are listed with FSR 3 support on AMD’s FidelityFX landing page. This is largely due to the ubiquity of Nvidia GPUs and, therefore, an obvious preference for DLSS support in games. DirectSR’s FSR 3.1 support is likely to come with a much easier workflow for implementing the tool and a wider berth of high-end upscaling support for AMD users.
