I've looked at a lot of questions and answers concerning pen pressure in this forum, and I've tried a lot of things to fix this problem. I have a Genius MousePen 6x8 and use Photoshop CS5.1. It's been a while since I used my tablet, but it used to work before. I rebooted my computer a while ago, so I installed the new driver from the Genius website. The tablet is working fine, even the pen pressure, but for some reason it just won't work in Photoshop. I've tried to fix it by resetting the Photoshop settings by using the Ctrl+Shift+Alt, I've reset the brush tool, I've played around with the brush options and nothing has worked.
Here is the image of the pen pressure working:
And here is the image of the settings for the brush and the pen pressure not working:
Thank you for your time!
Your tablet driver isn't reporting pressure correctly.
The knockoff tablet drivers usually need to be revised for each new version of Photoshop (and we have no idea why).
Contact your tablet maker to see if they have updated drivers to fix their bugs.
