User tests MiniMax H3 settings on RTX 3090 for optimal image generation

A user on Reddit conducted 112 tests using the MiniMax H3 model on an RTX 3090 graphics card to identify optimal settings for image generation. The tests systematically varied model/LoRA combinations, resolution, and step counts while keeping other parameters constant. The user found that the C3 model configuration, specifically at 0.8 MP with 10 steps, yielded the best quality at approximately 256 seconds, while a balance of speed and quality was achieved with C3 at 0.8 MP and 6 steps, rendering in about 166 seconds.
