Huion H640P Pen Lag

My Huion H640P tablet pen faces a lot of lag when I try to paint on Photoshop. This was not the case when I had just started to use the tablet. But it started lagging after a few months of use. 

  • Hi  Megha Nagar, please uninstall the driver you use now, and install the newest Driver_14.8.129.1220_beta to check whether the problem can be solved. 

    If this driver can not solve the problem, please try the method below:

    Created a PSUserConfig.txt file in Photoshop settings folder: [Disc]:\Users\[User Name]\AppData\Roaming\Adobe\Adobe Photoshop CC 2020\Adobe Photoshop CC 2020Settings\
    Added these two lines in the PSUserConfig.txt file and saved:
    # Use WinTab
    UseSystemStylus 0


    Moreover, please reply to us in the ticket so we can help resolve your issue.


    Best regards,
