Optimizing Performance with RTX 4000 Series Graphics Cards

If you’re using Nvidia’s RTX 4070, RTX 4080, or RTX 4090 graphics cards, there’s excellent news! The latest version of AUTOMATIC1111 fully supports these video cards (with torch 2.0 and CUDA 11.8), allowing you to leverage their power for quicker and more efficient image generation.

Below, you’ll find details on how to benchmark your setup and optimize the speed using specific parameters.

Benchmarking Your Setup

To ensure your setup is working correctly, you can benchmark the speed of image generation. Here are the settings for the test:

• Batch Size: 4 (Note: Using a batch size of 1 is not recommended, as the measured speed may vary based on other system components)
• Batch Count: 10
• Image Size: 512×512 pixels
• Sampling Steps: 20
• Sampling Method: Euler a
• Model: SD v1.5

What to Expect

• Speed Measurement: You’ll see the speed of generating each image, expressed in iterations per second (it/s).
• Picking a Stable Value: Usually, a stable value like the 5th batch is a good representation. For example, with RTX 4090, you should get about 10 it/s (note that this is 4 images per iteration), representing the max speed achievable today.

Speed-Up Options

You can further enhance the speed with one of the following parameters:

Option 1:

• Command: --xformers

Option 2:

• Command: --opt-sdp-no-mem-attention --no-half-vae --opt-channelslast
• Note: Option 2 is slightly faster, but it is recommended to test both options to determine what works best for your system.

Leveraging the Power of RTX 4000 Series

With the support for RTX 4000 series graphics cards, AUTOMATIC1111 unlocks new potentials in speed and performance. By benchmarking and applying the correct speed-up options, you can ensure that your setup is operating at peak efficiency.

Remember, these guidelines and optimizations are specific to the RTX 4000 series, so apply them accordingly. Your creative journey with Stable Diffusion has just gotten a significant boost, letting you generate more complex images faster than ever before.

How to keep Stable Diffusion Up-to-Date on your Windows Device

Stable Diffusion’s AUTOMATIC1111 is a constantly evolving tool, with regular updates bringing new features, improvements, and fixes. However, your copy won’t be automatically updated. Depending on your needs and preferences, you have two main options for updating: either updating every time you run the tool or updating only as needed. Below, you’ll find guidelines for both methods.

Updating Every Time You Run

If you prefer to always have the latest version, you can configure AUTOMATIC1111 to update every time you run the webui. Follow these steps:

1. Edit the File: Open webui-user.bat in a text editor.
2. Add a New Line: Insert git pull before the line that calls webui.bat. The file should look something like this:

   @echo off
   set PYTHON=
   set GIT=
   set VENV_DIR=
   set COMMANDLINE_ARGS=--xformers --medvram
   git pull
   call webui.bat

3. Save and Close: Save the changes to the file and close the editor. From now on, the webui will update itself every time it starts, ensuring you always have the latest version.

Updating As Needed

For those who prefer a more controlled approach, updating only when needed might be more appropriate. This way, you can avoid potential issues with new releases that might contain unexpected bugs or changes.

Here’s how to update as needed:

1. Open Command Prompt: Press the Windows key, type “cmd,” and click on Command Prompt.
2. Navigate to Webui’s Directory: Type the following command (you’ll need to adjust %userprofile% if you installed it in a different location):

   cd %userprofile%\stable-diffusion-webui

3. Run the Update Command: Type the following command and press Enter:

   git pull

The tool will fetch and apply the latest updates from the repository.

Conclusion: Choose Your Update Strategy

Whether you opt to update every time you run AUTOMATIC1111 or update only as needed, keeping your tool up-to-date ensures that you take advantage of the latest developments and enhancements.

Remember, always be mindful of potential instability in new releases, and consider your individual needs and workflow when deciding on an update strategy. By following these guidelines, you can keep your AUTOMATIC1111 installation current and aligned with your creative goals in AI image generation.

Troubleshooting: Resetting and Reverting the Stable Diffusion Windows UI

Sometimes, while working with Stable Diffusion’s AUTOMATIC1111, you might encounter issues with the webui, such as errors during an update or accidental modifications to some files. In these situations, you may need to reset the webui folder or even revert to a previous version. Below are the steps to perform both these actions.

Resetting the Webui Folder

If you run into errors while updating (e.g., with git pull), it’s likely that some files have been accidentally altered. You can reset the entire webui folder to its original state with the following commands:

1. Open Command Prompt.
2. Navigate to the stable-diffusion-webui directory:

   cd %userprofile%\stable-diffusion-webui

3. Reset the folder with:

   git checkout -f master

4. Finally, run the update command again:

   git pull

Warning: This process will reset all files in the folder, including any changes you made to webui-user.bat. You’ll need to make those modifications again if necessary.

Reverting Back to a Previous Version

If the latest version of webui is causing issues, you might wish to revert to a previous version. Here’s how to do it:

1. Find the Previous Version: Go to this page to view previous versions. Each row represents a different version.
2. Select a Version: Choose the version you want to revert to, considering the date and comments.
3. Copy the Hash Code: Press the copy button to grab the hash code of the chosen version.
4. Apply the Reversion: Open Command Prompt and run the following commands, replacing the hash code with the one you copied:

   cd %userprofile%\stable-diffusion-webui
   git checkout YOUR_HASH_CODE_HERE

If you encounter errors during this process, refer to the section on resetting the webui and try again.

Conclusion: Managing Your Webui Versions

The flexibility to reset or revert your webui allows for greater control and stability in your AUTOMATIC1111 installation. Understanding these processes can help you troubleshoot issues quickly and efficiently, ensuring a smoother experience with your AI image generation activities.

Remember to exercise caution when making these changes, as they can overwrite modifications or even lead to temporary incompatibilities with your current setup. Always consult the release notes and other resources available on the AUTOMATIC1111 website for guidance on which version is most suitable for your needs.
