We have already looked at all the details regarding AMD’s newly launched FSR 2.0 (FidelityFX Super Resolution 2.0) technology. All the FSR 2.0 source code has been published on GPUOpen recently. FSR 2.0 plug-ins have now arrived in the Unreal Engine library shortly.
Currently there are only four games that support the new version. However, with the official AMD announcement, we learned that at least 20 games will soon have FSR 2.0 support. Unreal Engine support will enable this technology to reach more games.
FidelityFX Super Resolution 2.0 is based on temporal amplification and is not as simple as its predecessor. FSR 2.0 will bring improved image quality compared to FSR 1.0 at all preset quality settings. This will be possible in part thanks to the transition from spatial to temporal amplification with “optimized” anti-aliasing features. When spatial amplification is used to amplify a frame, it only uses data provided by the frame itself. In contrast, temporal amplification can use data from the current frame as well as previous frames. Interestingly, NVIDIA’s DLSS 1.0 was also a spatial amplification solution, with DLSS 2.0 transitioning to temporal amplification.
AMD FSR 2.0 now joins the NVIDIA DLSS 2.0 plug-in for Unreal Engine 4 and 5. This means developers can now choose between the two technologies or even incorporate both into their games.
