You could also consider generating lower-resolution images as they are less resource hungry on your GPU. To do so, simply change the height and width values of the output to be generated inside Stable Diffusion.
FIX 5: Reduce sample size to one
The more the merrier might not be true for such resource-extensive tasks, so you should consider reducing the output sample size to 1 so as to lower the overall burden on the GPU. To do so, you’ll have to enter “–n_samples 1”.
FIX 6: Edit webui-user.bat
For the unaware, Stable Diffusion uses the WebUI-user batch file to execute the required commands for generating images on your PC. So you could edit this file via notepad and add a few optimisation tweaks as mentioned in this GitHub page or check out these Reddit posts (1,2,3).
