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. Plus, DLSS 1.0 games don’t look nearly as good as games with DLSS 2.0 and later. There are currently more games in total supporting DLSS, but DLSS has also been out for two and a half years longer than FSR. For one, there aren't many games that support both FSR and DLSS. 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. FSR is also an open-source technology and doesn’t require specialized graphics hardware. DLSS, meanwhile, only works with Nvidia GPUs. 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 is currently on version 2.2.1, while FSR is in its first iteration. Nvidia’s take on upscaling, DLSS, came out more than two years before AMD released FSR in June 2021. The open-source technology already works with numerous operating systems and APIs, including DirectX 11, DirectX 12 and Vulkan. This is one of the reasons AMD says FSR is easy for developers to incorporate. Upscaling and sharpening of frame data generally works a lot better than upscaling text.įSR doesn’t require any special training for individual games or temporal data from prior frames. There are some caveats, however, as if a game doesn't directly include FSR support, that means everything - including UI elements and text - will have the scaling factor applied. Modders have also brought FSR to SteamVR and most Vulkan-compatible games. Here's a list of games that currently support FSR, along with games that are expected to get FSR support in the future, as per AMD. To utilize AMD FSR, the main thing you’ll need is a game that supports FSR. Dynamic scaling would allow games to render at anywhere from native resolution to 50% of native resolution, and everything in between, normally with a target framerate specified in the game. That scaling factor applies in each dimension, so as an example, 3840 x 2160 with Quality mode would render at 2560 x 1440 - 44.4% as many pixels total compared to 4K.ĪMD also has plans for dynamic scaling factors, though this hasn't been implemented yet. Ultra Quality uses a 1.3x scaling factor, while Quality uses 1.5x scaling, Balanced uses 1.7x scaling and Performance uses 2.0x scaling. The four modes run at different levels of upscaling. And, like the highest level of performance with Nvidia’s DLSS, you can expect noticeable artifacts with FSR Performance mode. But more upscaling results in more visual artifacts. With the highest level, Performance mode, depicted in the above chart, AMD claims you’ll see an average performance gain of 2.4x at 4K resolution. UI elements and text are then applied to the final output.ĪMD FSR has four different modes: Ultra Quality, Quality, Balanced and Performance. The resulting image is then upscaled to the target resolution, resulting in higher performance than 4K and sharper detail than 1080p.

FSR allows a user to render at anywhere from 1440p (FSR Ultra Quality) to 1080p resolution (FSR Performance), which will make hitting higher framerates easier, with two other options as well. That could prove useful for high refresh rate 1440p displays, some of the best gaming monitors, but it can also help smooth out framerates on older GPUs and gaming laptops.įor example, a game might not run particularly well at native 4K rendering. While FSR can definitely help in performance-heavy games and titles with extensive effects, like ray tracing, it can also work as a general purpose algorithm to simply boost performance, even on games that already run fine. AMD doesn't directly promote FSR as a competitor for DLSS, mostly because it sees FSR as having application for a wider variety of games.
