Game Capture only records top left of game.

I tried using display capture, which worked for very low cpu/gpu usage games like stardew valley, because I could set the game to my base monitor resolution [3840x2160], but I cannot do that for star wars battlefront 2. It causes a TON of lag. my stream canvas is 1920x1080 as is the scaled resolution. When I try to record battlefront 2, my entire screen is filled up with the game... but only the top left corner of it. When I set the game's resolution to 1920x1080, it includes MORE of the game, but still not all. Help?
