Issue: [Bug]:  CUDA out of memory, Stable Diffusion failed to load
Labels: bug-report

### Is there an existing issue for this?

- [X] I have searched the existing issues and checked the recent builds/commits

### What happened?

After running webui-user.bat and installed all required files, it fails to load. I have entered what I think to be the required BATCH edit, but im not completely sure: 

@echo off

set PYTHON="C:\Users\chron\AppData\Local\Programs\Python\Python310\python.exe"
set GIT=
set VENV_DIR=
set COMMANDLINE_ARGS=--lowvram --xformers --disable-nan-check --opt-sub-quad-attention --sub-quad-q-chunk-size=128 --sub-quad-kv-chunk-size=128 --sub-quad-chunk-threshold=80
set PYTORCH_CUDA_ALLOC_CONF=garbage_collection_threshold:0.6,max_split_size_mb:128

call webui.bat

P/S: It could have some issue with --xformers commandlinearg because it doesnt load with it, and im not sure how to fix that either.

### Steps to reproduce the problem

1. Go to ....

### What should have happened?

After installing all files it should have opened to the UI
