Does it really? I've found that playing Doom Eternal normally increases the chances of getting my ass handed to me in Counter-Strike. Most mainstream shooters are extensively built around mechanics like cover shooting and burst firing that Doom tends to completely shun and even punish at times. Play too much Doom and you'll be accustomed to just breaking into the middle of the field and throw caution and covering into the wind, which is a great way of getting killed in seconds in games like CSGO, Battlefield, Apex Legends, Valorant and CoD.
