:: "--disable-async-offload" added because of this : ComfyUI has added async weight offloading by default, not compatible with older GPUs, try without it , if it works you are good.
:: "--disable-pinned-memory" added , because it seems to be the cause of many recent problems with generation using zluda.

:: in the comfyui-user.bat remove the dots on the line below and change the gfx1030 to your gpu's specific code.
