Version 3 is far more accurate and realistic in every aspect! I wanted to redo my first ever lora I created and I'm very pleased with the results.
Recommended Settings...
On A1111 for realism for this particular lora I recommend DDIM with Karras, (DPM++ SDE + Karras is also good),
Steps 25-40 (30 is the sweet spot)
CFG: 5-6
Size: 512x768
Hires: Denoising Strength: 0.30, Hires upscale: x2, Hires steps: 15, Hires Upscaler I highly recommend: 8x_NMKD-Superscale_150000_G also (1x-ITF-SkinDiffDetail-Lite-v1 or R-ESRGAN 4x is also good).
Adetailer: mediapipe_face_mesh_eyes_only and use the <lora:lora_perfecteyes_v1_from_v1_160:1> photo of perfect eyes, detailed perfecteyes subtle blue eyes" in the positive prompt.
