Re: 0.472b Game Capture flickering
Would need to see a log file -- nothing has actually really changed for game capture between the versions outside of simply allowing them to work cross-bit, which was added in 0.471b. If you want you can check out 0.47a and see if you still have the same problem or something.
Game capture flickering is usually only reported by people with multi-GPU systems or dual-GPU laptops who have OBS set to use the wrong GPU.
