I'm using Photoshop CS6 on a PC. When I tried to apply the oil pain filter, I got an error message saying "The filter you were using encountered an unknown graphics processor error that caused an unexpected exit. Check the manufacturer's website for the latest software." Could you let me know on how to fix this? Thank you!
Do what the error says: check your GPU vendor's website for updated drivers.
I believe what this is saying is you need to update your video card driver as it is not up to the job. Go to makers website and download.
You might also get some relief if you change the advanced graphics card preferences to Basic. (edit/preferences/performance).
Hope this helps.
