Thin Mesh Flickering with Temporal AA

Hey guys! I’ve seen a lot of post that touch on this subject but haven’t found a good solution yet. I have a lot of thin geometry in my scene and even at medium distance it flickers. I’ve tried adjusting the bounds of the mesh, different AA types, removing lod and console command to increase temporal AA samples. I really do think this is a AA issue because when I switch to FXAA the flicker goes away but presents different problems and would very much like to stick with Temporal because it does overall look better. When I enter in console a command like this one.
r.TemporalAASamples=64
It doesn’t seem to do anything, is there something I may be missing?

Thanks!
