Hi,
I just received my new GTX 660 Ti (MSI power edition) and when I capture during the game, it suffers of micro freezes. It films for 5 seconds then it has a micro freeze (less than 1sec) then smooth for 5 sec and again micro freeze, and so on. (exactly 5 seconds each time)
I have the latest version of Mirillis and Nvidia drivers 310.61.
I tried it on several games, same results.
I uninstalled it and installed it 5 times.
Fraps and MSI Afterburner work fine but Mirillis Action is much much better.
