Sr2 has it. it's literally a free asset on the unity asset store. just put it in after 5 years or however long this game existed for god's sake.
Reshade works half the time and is a pain to set up with the depth and this and that.
and advanced rendering stopped working years ago.
ambient occlusion would make this game look atleast passable.
even better if it had some bloom
some volumetric clouds would be nice as well.
I don't see any reason not to add this.
And if some people's devices can't handle it, we can have an option to disable it.
