AHK Script Causes Lag in Photoshop with WinTab

AHK Script Causes Lag in Photoshop with WinTab Enabled

In some cases, using the AHK (AutoHotkey) script with WinTab enabled can cause lag in Photoshop, particularly when a white block appears near the cursor in real-time. This issue has been reported by some users who have added the following line to their PSUserConfig.txt file:

Understanding the Problem

WinTab is a feature in Windows that allows tablet devices to use their pens as a mouse. When this feature is enabled, it can interfere with the performance of some applications, such as Photoshop. This is because WinTab sends a constant stream of input data to the application, which can cause it to become unresponsive or laggy.

AHK (AutoHotkey) is a powerful scripting language that allows users to automate repetitive tasks and create custom keyboard shortcuts. However, when used in conjunction with WinTab and Photoshop, it can exacerbate the lag issue.

Testing the Script

To test whether the AHK script is causing the lag in Photoshop, follow these steps:

1. Close Photoshop and any other applications that may be using WinTab.
2. Open the PSUserConfig.txt file and add the following line:

3. Save the file and restart Photoshop.
4. Open the AHK script and test it to see if it causes lag in Photoshop.

Potential Solutions

If the AHK script is causing lag in Photoshop, there are a few potential solutions:

1. Disable WinTab: Open the PSUserConfig.txt file and add the following line:

2. Modify the AHK script: If disabling WinTab is not an option, you can try modifying the AHK script to reduce the amount of input data it sends to Photoshop. For example, you can try adding a delay between each input event or limiting the number of input events that are sent per second.
3. Use a different scripting language: If modifying the AHK script does not solve the issue, you can try using a different scripting language that is less resource-intensive. For example, you can use a language like Python or JavaScript to automate tasks in Photoshop.
