I solved a problem with my new laptop and After Shot Pro.
AS doesn't start on Windows 8 and AMD switchable graphic device, the startup process endend up in a "Aftershot Pro has stopped working" message.
The AMD catalyst driver with version 12 doenst support switchable devices, I've installed the 13 beta 7 drivers from http://support.amd.com/us/kbarticles/Pa ... river.aspx
After installing this driver everything runs fine!
So I hope I could help someone
Sorry or my bad english
