This is one of the reasons AMD says FSR is easy for developers to incorporate. The open-source technology already works with numerous operating systems and APIs, including DirectX 11, DirectX 12 and Vulkan. Nvidia’s take on upscaling, DLSS, came out more than two years before AMD released FSR in June 2021. DLSS is currently on version 2.2.1, while FSR is in its first iteration. There are quite a few major differences between FSR and DLSS.įirst, AMD FSR is GPU-agnostic, allowing it to work with GPUs from brands other than AMD. DLSS, meanwhile, only works with Nvidia GPUs. FSR is also an open-source technology and doesn’t require specialized graphics hardware.
AMD believes this "will accelerate the adoption of FSR into many more games for more gamers than other upscaling solutions." DLSS, meanwhile, requires the Nvidia RTX cards’ Tensor cores. For one, there aren't many games that support both FSR and DLSS. There are currently more games in total supporting DLSS, but DLSS has also been out for two and a half years longer than FSR. Plus, DLSS 1.0 games don’t look nearly as good as games with DLSS 2.0 and later. Generally speaking, we’ve found DLSS to offer better image quality, but FSR allows for greater framerate boosts because it’s not as computation-heavy as DLSS. Our FSR performance and image quality testing found that framerates scale proportionately to how much you reduce the rendering resolution. For example, both FSR and DLSS can help you reach the 60 frames per second (fps) standard, but the story changes when you're trying to get a game running at 120 fps to hit 240 fps - for example, to accommodate a 240 Hz display.
