My game is lagging a lot when it is still a basic game

I’m trying to create a FPS game and a made a little demo scene. There aren’t even any ai enemies yet and the game is lagging like crazy

Given the information in the comments, i’d guess you either added too much objects in your scene, you used objects that are too complex so your computer has a hard time rendering/manipulating them OR , the likely case, you put too much calculations in one of the per frame methods such as Update, FixedUpdate, maybe even big calculations inside an infinite loop (unintentionally).

I suggest you first comment all the code to check if the scene objects themselves cause the slow down. Then, if not, uncomment your code bit by bit to see which part explicitly is the cause. It’s faster this way for beginners.
