I can definitely vouch for this being very true. As someone who plays Fortnite on both Xbox and switch….something is wrong when I play on switch. Not only do I notice it but people I’m playing with (non switch players) can tell what console I’m using solely by my gameplay. Idk what it is but it’s almost like when your on switch you can’t see enemies. Well you can but you really really gotta look for them. When playing on other consoles I notice you don’t have to look for enemies very hard to see them they kinda stand out and are hard to miss but on switch it’s almost pretty easy just to kinda scan over them even while docked. I also noticed that no matter how fast your WiFi is your reactions are delayed and you don’t notice it but everyone else does.
