Currently as of today, I’ve been working on an open world game for around 2-3 weeks. The game has right now more than 70k parts on only roads, with buildings I must say the final game could have 150-200k.
And also the game contains a lof of terrain. Can this game be achieved and have no performance issues even with the correct optimization? Can streaming help here or will it make the performance worse? Should I even bother making this?
ROBLOX handles render distances quite well depending on the players settings. If you have a single part that is extremely big and possibly goes outside the render area for a player then there will start to be some performance issues for lower end devices. Keeping note that alot of players play on mobile. You can also try playing the game on your phone whilst looking at the performance stats in the game settings ui
