My Photoshop CS6 crashes when both VGA-s are enabled. If I disable the Intel HD 3000 in Device Manager it works fine.
The error: Problem signature: Problem Event Name: APPCRASH Application Name: Photoshop.exe Application Version: 18.104.22.168 Application Timestamp: 4f61c045 Fault Module Name: aticfx64.dll Fault Module Version: 22.214.171.1240 Fault Module Timestamp: 52540642 Exception Code: c0000005 Exception Offset: 00000000000a1a4e OS Version: 6.1.7601.2.1.0.256.1 Locale ID: 1033
AMD Radeon HD 7770 (Gigabyte) Intel HD 3000 (Core i5)
I use both cards, because I have 3 monitors:
1 VGA on Intel 2 DVI on AMD 3 Mini display port on AMD
All drivers are up to date, I use 64 bit Windows 7, all updates are installed. Photoshop is also 64 bit. System memory: 16 GB.
When I start Photoshop, Graphics Processor Settings are grayed out (Photoshop detected an error in your display driver.) With Intel HD 3000 disabled it works.
