How do I push AI portraits (generated by ChatGPT) from ~9.0/10 realism to 9.9+/10 without identity drift? (RTX 3050 4GB, ComfyUI)
Im building an AI influencer and have hit a realism wall.
The images are already good in terms of:
Consistent identity
Anatomy
Clothing
Backgrounds
Composition
The remaining issues are all microdetails:
Plastic/smooth skin
Weak pores & skin texture
AI-looking hair strands/baby hairs
Slightly synthetic eyelashes/eyebrows
Phone camera realism (lighting, optics, sensor look)
Hardware:
RTX 3050 Laptop (4GB VRAM)
Ryzen 7 5800H
24GB RAM
Windows 11
ComfyUI (--lowvram)
I've already tried:
FaceDetailer (low denoise = almost no change, higher denoise = identity drift)
Different checkpoints
Upscalers
SUPIR (VRAM/model loading issues)
At this point, I'm not looking for generic "use FaceDetailer" advice.
My goal is simple: improve skin, hair and overall photographic realism while preserving the exact identity.
If you had my hardware, what workflow would you build today?
I'm open to completely different approaches (tile refinement, restoration models, img2img, post-processing, camera simulation, etc.). If you've actually solved this problem, I'd really appreciate hearing your workflow.
