### What options to use for low VRAM videocardsd?
- If you have 4GB VRAM and want to make 512x512 (or maybe up to 640x640) images, use `--medvram`.
- If you have 4GB VRAM and want to make 512x512 images, but you get an out of memory error with `--medvram`, use `--lowvram --always-batch-cond-uncond` instead.
- If you have 4GB VRAM and want to make images larger than you can with `--medvram`, use `--lowvram`.
- If you have more VRAM and want to make larger images than you can usually make, use `--medvram`. You can use `--lowvram`
also but the effect will likely be barely noticeable.
- Otherwise, do not use any of those.
Extra: if you get a green screen instead of generated pictures, you have a card that doesn't support half
precision floating point numbers. You must use `--precision full --no-half` in addition to other flags,
and the model will take much more space in VRAM.
