How to make a game less laggy

[Aurution]

Hello! I am making a game. It is pretty detailed, but I want to avoid lag. What is the best way to avoid lag when building big detailed creations?

You can try StreamingEnabled which offloads areas of the game which your player camera is not looking at. There is also a few default options available for StreamingEnabled the out behaviour. Please note that if you were to use something like LowMemory it may affect textures in your game or cause slight lag if not implemented correctly. That is the best advice I can give regarding streaming. I usually have it disabled because of my clever low poly tricks but please let me know if this makes any difference.

*If you are talking about lag whilst making the game in Roblox Studio you can go to Studio settings and lower the render/edit quality

Some of the way in studio
you can turn off shadows while editing.
or do not used auto at Edit Quality.

Some of the way for in game
delete trash scripts (what you did not use)
delete other things in workspace that you never use.
do not use terrain with more than 40 studs or spam them in a place where you can’t see.
Don’t place a Point Light (shadows on) near to many part.
don’t use ugly mesh parts.
make you UI manually (with multiples of 2 and 5) for size and position.
also do not always drag your models (to a no smooth terrain or something like it).

How to stop lag in a large part game

You will want to start by doing the basics, which are outlined in the roblox API reference: Once these are done you can get more specific with your issue, but this is a good place to start. Edit: depending on what the player is doing in the game and the map, you can look into Streaming Enabled so that parts of the map only render when player is close to them.
