I am using the surface slim pen 2. I have tested it between photoshop and fresco and other software and found that in fresco it is having a problem when light pressure is applied, it seems like the minimum pressure is a noticable amount higher.
The best I have been able to do is increase the minimum on the pressure curve so that it is above 0. This seems to at least give me more consistently results but i still feel as though i have to apply more presure. The photoshop curve is just left as the default linear curve and is fine
