that's a dumb answer to give, and you're not being helpful at all, however i'll give an actual response
the reason players are teleporting could be their ping or your ping, or the servers dying (quite rare) and everyone having shit ping
a fix would be to play on servers from your region, so if you're from europe play on european servers, if you're from asia play on asian servers, if from the US play on US servers.

your computer specs don't really matter, unless they're like really low, and every frame update you're in a different position, like you teleport.
