Try Tcomb. There's a guide on how to find the settings in the wiki. Go low, it does artifact.
Also, this doesn't need sharpening, and line darkening is cancer.
I'd use smdegrain(prefilter=0, thSAD=70) to clean up the noise. And a light high bit depth debanding never hurts. Gradfun3 is a staple for me.
