Ive tried it before... It wouldnt work. Its most likley my PC... I know Ive set it up right. I got a spider-man game working with it. You see, when I load it in JA the interface doesnt "appear" like it does with spider-man. I think its because GameCam uses OpenGL, and JA is mainly an OpenGL application
I think only really good cards can use it, which mine isnt.
It does seem to be a "more well put together" application, when compared to FRAPS (considering... this one looks better and has other stuff...) not to mention you have to compress the FRAPS video a LOT! My trailer alone was over a gig.
