GOMac, Make invisible all bodyparts under clothing and any "arm or leg" out of view. Turn visible in RayTracing off on hair. Cast shadows too, if it's short hair. Try to have just one shadow enabled light. Use IBL for fill. Don't use bumpmaps unless it's really a must. In rendersettings, Try to stay above 1.00min shading rate (hair) and below 2048max texture(drop it to 1024 if you can). No filters! Preset bucket at 16. The least RayT bounces if using AO or reflects. Check use displ maps , RayT (optional) and cast shadows only All I can imagine right now,,,screenshot? It could help... Hey Maxxx!
