Future's definitely looking bright for FSR 2.
IMO it'll go the way of FSR 1 with widespread adoption by game developers.
Now Techpowerup has a Metro Exodus Enhanced Edition FSR 2.0 Community Patch review up.
Metro Exodus Enhanced Edition recently got support for AMD's FidelityFX Super Resolution 2.0 through a community mod. The addon converts the officially supported DLSS render path into instructions the AMD FSR 2.0 algorithm understands, and results are excellent.

Conclusion
In Metro Exodus Enhanced Edition, none of the anti-aliasing and upscaling solutions are using sharpening filters in the render path. However, you can still adjust the setting manually in NVIDIA Control Panel or AMD Radeon Software. With FSR 2.0 active, image quality is very noticeably upgraded at all resolutions compared to native TAA. FSR 2.0 deals with small thin objects that are far away better, like wires or tree leaves, for example. The quality of vegetation, grass in particular, is improved by eliminating shimmering at lower resolutions, and the image is less blurry overall. In "quality mode," FSR 2.0 delivers better image quality and performance while running at lower internal resolution.
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 and enemy creatures at medium and far distances and player weapon while moving quickly, on weapon scopes in particular. We also found shimmering issues on steel objects 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 FSR 2.0 needs different mask inputs vs. DLSS 2.4 to hide things such as particles from the reconstruction. To be fair, DLSS 2.4 also has the same issue (black trails on power lines), but it's less visible on the DLSS 2.4 image. Just like in other games we tested, 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. The ray tracing features, like reflections, are working as intended with the FSR 2.0 mod applied.
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. The most noticeable difference between DLSS 2.4 and FSR 2.0 is temporal stability. While moving through the world at day time, FSR 2.0 image stability is slightly less stable than DLSS 2.4. Performance-wise, 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 across all resolutions. Metro Exodus Enhance Edition is the first game that absolutely requires a ray tracing capable graphics card—there is no "RT off" render path. Since DLSS is an NVIDIA-exclusive technology, Radeon users were left behind without a high-quality upscaling solution and stuck with lower framerates. With this FSR 2.0 mod applied, AMD RDNA2 owners now have the ability to play Metro Exodus Enhance Edition at much higher performance with only a small loss in image quality.
