I can handle 8 players on my studio no problem but when i publish the game and play with someone else it lags? server issues?
The reason for that is because studio uses your normal local network in order to do that, when you publish the game and play it on website, the roblox servers are hosting the game, the latency speed depends on how fast your internet is and how far the server is. (as far as I know those servers have a really good upload speed so its improbably that the server is having any latency, but yesterday it seemed like that roblox servers had an problem, probably already fixed), so the only ways I know you can have your game running faster is getting a better internet provider with less ping, and/or changing your internet dns. That is all I know.
