I haven’t seen games take this approach. Most do TAA and adjust sharpen to a preferred amount. Some add a SMAA or FXAA step afterwards.
Mine uses some tricks to undo the blurriness on textures while trying to not sharpen the anti-aliased edges. It also doesn’t change anything else as it happens right after TAA, and only when TAA is enabled.
Download and test it out! I think it’s much better than using r.TonemapperSharpen.
