Hi Depending on distance to figure...and your lights (very important), using manual settings... Lower the min shading rate (0.5,etc) raise max texture res (1024, 2048, 4096). Increase pixel samples 5,6,7... Turn filtering off. Render to a large (res)(1400x1000) or bigger. load your hi res to whole body. A bump setting will help. You can pull a wire from texture to bump and set it to 0.01(inches), save it to material library(torso) and click it onto rest of body. Same for head. Same for teeth/gums...too many settings to list here... There are a lot of shaders available to go futher than this. Try 1st with just a body...no hair no props. Hi res is tough on the system.
