It makes models more fatter, which means its much more easier to shoot. I found that it also gives more fps.I will never understand people who stretch their screens in CSGO or on perp, like what does it even do? It just makes your game look like shit.
I also found that recoil in stretched is much more easier to control in some weapons, such as the mini uzi.They aren't easier to shoot, they're easier to see. The size of the models doesn't change in-game, only what they look like. It's a negligible difference to gameplay that you should only really do if you're that starved for slight advantages over opponents and want better FPS
ask @Locksmith he would knowIt's not worth it at all, your phone ends up taking all of your screen as well
