Some good points came out of Mike's post, which raised a question that I'm hoping others can shed some more light on. @Wojciech Solarczyk made a good point about live monitoring "finding a bottleneck requires live monitoring: are you running out of VRAM? RAM?" The question I have is at what benchmark should you be looking for to know you are bottle necking? Based on a current render, my stat's are: Ram 76%, GPU 100%, VRAM 95%. Note that I'm only using KitchenAtt and Ref2VA_int8_pruned_convrot. I know this is not the fastes for a 5070ti, but i believe it keeps the quality decent, albeit this is still an area that is a soft spot for me as there are so many models and lora variations out there. Similar to Mike, I did discover that I need to keep the chunks bellow 13s, otherwise render times turn into full days vs 15-20min.
