This behavior kicks in when the GPU memory is almost full (e.g. for very large images). This slows down rendering by nearly 20 times. + +If you're on the latest NVIDIA driver, you can disable this behavior in the driver settings to prevent Easy Diffusion from using shared memory. That setting will be only for Easy Diffusion, it won't affect other programs. + ## RuntimeError: CUDA out of memory This can happen if your PC has less than 6GB of GPU RAM.
