My quick tests showed that FP8 sometimes give a textures with barely noticeable regular grid pattern (repeating grain noise on skin or sky, for example). It is needed to focus on textures to see, but sometimes noticeable. Let me know if you see such artifacts or other issues.</p><p>Recommended parameters and workflow can be extracted from my samples.</p><p>👇 READ THIS PLEASE 👇</p><p>I prefer 2-stage rendering. Text-to-Image at 0.75..1.2 MPx resolution (the lower resolution, the less stuff in scene) with any compatible sampler (Euler, sa_solver), er_sde, dpmpp_2m, seeds_2, seeds_3, gradient_estimation, exp_heun_2_x0_sde). Second pass (HiRes Fix) I'm doing with Details Daemon node. Krea 2 Turbo have a very tight CFG range (0.9..1.5). You cannot adjust contrast and details using CFG knob, because you need to be much more precise. Details Daemon let you smoothly regulate CFG scale depending on Time Step.</p><h3 id="v1g-int8-cobvrot">v1g INT8 COBVROT</h3><p>Turbo workflow (10 steps) ==&gt;&gt; <a target="_blank" rel="ugc" href="https://civarchive.com/images/141569765">https://civarchive.com/images/141569765</a></p><p>Made from v1e (All in One) by applying more fine-tuning and quantization script to convert it into INT8 CONVROT.<br />For me it looks less contrast (better use 20 steps and CFG 3..5 or more).

Just use my workflow or use a regular Load Checkpoint node in ComfyUI combined with a regular KSampler. Nothing tricky needed. If you adapt the SDXL HiRes Fix technique described below, you may get better textures, but with v1e even single Text-to-Image pass at 1MPx resolution works well for me.
