NVIDIA Manage 3D Settings for Visual Studio 2012

I want to change 3D settings for VS2012 from NVIDIA Control Panel but when I open Program Settings tab then select MSVC (devenv.exe), second select box which is for select graphic processor for program is not becoming enabled. Control Panel automaticly selects Integrated Graphics which is Intel HD 4000 and I am not able to work (or change for NVIDIA) with GPU. My driver 347.88, card GeForce GT550M and CUDA 6.5 installed on Windows 7 x64 Asus N53SN laptop. What should I do?

Hey Orkun, any luck on this question of yours? I’m also wondering about this setting
