So I'm quite new to tactical shooters like valorant or csgo, only played for about a month or two and I noticed this very bad habit of mine that keeps me away from getting kills quickly enough so that I won't die. Everytime I peek or see so...

I literaly have no idea how to record a match. Which application is the best? I dont have a high end pc so... I need something optimized Im diamond trying to reach ascendant, i feel i cant improve enought without vods
