I am using CS5. I have the Pixel Bender filter loaded and it appears in my filter menu but when I try to use it when working with a picture all I get is a blank screen. I am using windows xp and have installed a Radeon HD 4350 with a 512mb capacity. I also using Topaz plug-in filters that work correctly. I wanted to work with the tutorial for Pixel Bender that is covered in the Photoshopusersgroup.com tutorials. Can you help me?
Are you sure you've installed the latest drivers, from the AMD website, for your graphics card? What are the dimensions in pixels of the images you are using? Do you see this problem with all Pixel Bender filters?
