I can't get the hardware acceleration working and the resulting information is "Hardware acceleration cannot be enabled on this computer. Your video card doeas not meet the minimum requirements for this game". It's a Windows 8 laptop with dual GPU (Intel HD 4000 and Radeon 7670M with drivers fully up to date and other games working). Other PopCap games like PvZ are also affected. It used to work on Windows 7. Any ideas?
