I couldn't commit, so I'm waiting for dev comments/review. There is a work about FXAA (​https://wildfiregames.com/forum/index.php?/topic/20175-programmer-graphics-gameplay-ai-mikita-hradovich-yet-another-game-developer-wants-to-participate/&page=2), but it looks blured. I will test FXAA & SSAO, but I'm not sure that will be ok.
