Compared to native TAA, FSR 2.0 image quality is a very noticeable upgrade across all resolutions. The in-game TAA solution has a very blurry overall image across all resolutions except 4K, and very poor rendering of small objects detail—tree leaves, for example. All of these issues with the in-game TAA solution were resolved with this unofficial FSR 2.0 community patch.
However, as this mod is not an official implementation, it has some issues TAA and DLSS 2.4 do not. The most noticeable of those with this FSR 2.0 mod is excessive ghosting on NPCs at medium and far distances, very noticeable shimmering issues at lower resolutions, such as 1080p, and black trails on power lines while moving. In some scenarios, it may even look like smearing, which most people will find quite distracting. The issue with power lines is probably due to the lack of proper masking because it needs different mask inputs vs. DLSS 2.4 to hide things such as particles from the reconstruction. Also, the FSR 2.0 mod conflicts with in-game motion blur, creating black borders around the image as if squinting, so we recommend turning motion blur off.
Compared to DLSS 2.4, FSR 2.0 provides a similar level of image quality if we exclude the few issues described earlier, which may of course be fixed in the future. FSR 2.0 even surpasses DLSS 2.4 in the level of detail rendered in vegetation and tree leaves. Overall, with FSR 2.0 applied, small details in the distance are rendered more correctly and completely, and the image is less blurry and oversharpened at lower resolutions. The most noticeable difference between the in-game TAA solution and FSR 2.0 is at lower resolutions. In Quality mode, FSR 2.0 manages to deliver better performance and drastically better image quality while running at lower internal resolution. Compared to native resolution, the FSR 2.0 performance uplift is a great improvement to the game, and compared to DLSS 2.4 in this game, FSR 2.0 basically works identically to DLSS 2.4 in terms of performance gains at 1080p and 1440p, but at 4K resolution, DLSS 2.4 is superior than FSR 2.0 in terms of performance gains.
