Intensity Pro - Games reverts from 60 to 50

Dear Blackmagic specialists!

This is my first post at CreativeCOW. Whenever I'm looking for a solution to a creative video problem I end up here so I thought I would join. So far I haven't been able to solve this though, hopefully you'll be able to give me some ideas.

I bought the BlackMagic Intensity Pro to be able to record gameplay on another computer. Usually it works perfectly but I've run into trouble with Battlefield 3 and especially Bioshock Infinite. As you know, the Intensity Pro needs to have exact information about what's beeing sent. When I run 1080i 60 and record the desktop, Planetside 2 and severarl other games/applications everything works fine.

When I start Battlefield 3 and Bioshock Infinite though my screen (the gaming computer) reverts to 50Hz. In BF3 I can fix that by going in to the menu (where it's set to 60 fps), selecting another fps (any will do) apply the changes but not accept it when that question comes. For some reason that forces BF3 to 60 FPS. If I go into windowed mode and back the changes I just made are gone and the game is at 50 Hz again.

Unfortunately there is no selection for fps in Bioshock Infinite. I did record the first episode in Fullscreen Windowed but that resulted in some horrible screen tearing instead.

What I get on the gaming computer screen when it reverts to 50Hz is also a very strange image. It's hard to explain but it's almost like you've removed anti aliasing and smoothing on everything. The image is brighter and there are more edges everywhere. This is the best I can do to let you see the difference.

So besides the changes I have to make in Media Express (1080i 60 to 1080i 50) which takes me down to 25 fps progressive, I have to play the game with this strange setting.

Any ideas you have would be helpful and much appreciated.

My graphics card on the gaming computer is a GeForce 670 if that helps.
