I just picked up a used ATI 550 Pro capture card for 10 bucks. I have never used a capture card before I finally got it to show up on xsplit and I could see my game there and play. But the screen is super small lol.

I have zero clue what to do. Any software anyone can recommend or how I can play the game with a bigger screen then what's in xsplit?

Super noob at this.
