can we get a better fxaa shader ?

Hi developer, for now the fxaa for reshade 3 is no good as dx9 version port by somedude. AS you can see，luma pre-pass doesn't do and use linear srgb color space or something，and it causes a lot of artifacts and some color and edges untouched.Fxaa is good performance and compatibility，a pity if it was ignored.

And if it‘s possible to support dx12 & vulkan？Because it‘s no third party aa for these game now. Just fxaa is enough.I made a post before but deleted uncarefully, and this is my earlier post. reshade.me/forum/shader-discussion/517-a...about-fxaa-luma-pass

Hope the problem can be sovled soon, thanks. And have a nice day.
