Is this the first game of its kind? Its actually so cool in practice I'm excited to see this genre of game develop. Even with a 3080 waiting for the images isn't that bad i can only imagine how good it feels with a better gpu.
I've seen some project that with image generation on developer's server (non nsfw). To make image generation faster, there are several settings: 1) Options -> COPEtions -> disable second pass.(*2 speedup) 2) Options -> AI General -> Reduce "Image Generation Steps" (Proportional speedup, under 5 is not recommended). To make image generation less frequent, there are several options: 1) Options -> COPEtions -> Disable Minor Effects on Character (Mainly bodily fluids) 2) Options -> COPEtions -> Disable All Effects on Character (All effects except Invisibility, Muscle Growth, Dark Crown Curse) 3) Options -> COPEtions -> Disable Equipment Display. If you want to play as ~normal RPG, there is also Options -> COPEtions -> Disable Cutscenes.
