I have windows 7 64bit and geforce 630 gt .
My Cinema 4D disables Aero Peek while launching C4D .
It might have also disabled hardware acceleration; not quite sure about this; and enables Aero Peek after exiting C4d.
However I am able to turn on Aero Peek while I'm in c4d, but it's such a frustrating to have a black flash every time I start and exit C4DR13 or C4DR14. AND I am afraid it has also disabled hardware acceleration.
Can anyone help ? or faced similar issues while starting up Cinema 4D ?
