Hey guy's!
When i get my joystick back, im going to play alot and at the end make a movie.
But how do u guy's record in-game fotage ???
I was thinking about fraps, but my pc would not handel a 99fps recording with fraps..
Can u slow down the game in the console, so i can fraps with a low fps like 25-30. And then speed it up in sony vegas for smooth fotage.
Can this be done ?
But say your way to record
