Reducing Lag in Game?

Old post I know, but in case others run by here, it's worth noting that the scale of things in your game is nothing to worry about. If you decide to up everything 100 fold, so your game goes from -1000 to 1000 ins$$anonymous$$d of -10 to 10, it will not cause lag.

Coordinates are simply that, coordinates. It doesn't require more memory, nor is it slower to work with large floats than it is to work with small floats.

I am running into the same issue with my scene and game. Restarting Unity has no effect at all. I don't have the greatest of computer nor the worst. $$anonymous$$aybe a little below todays average in terms of ram and performance but I can play Assassins Creed Black Flag on low settings with $$anonymous$$imal lag so Im assu$$anonymous$$g that Ive done something to effect the performance somehow. As far as I know all of my models are .fbx as well which is what Ive read you should use.

I have between 20 -25k trees with colliders the map is a 3000 by 3000 height 300. In areas with little to no models such as buildings the lag is $$anonymous$$imal or non existant but at my Church Yard which has of course the Church and behind is the grave yard the lag is fairly bad.

I made a development build of my game which is 406 mb. Not even a gig so I figure it shouldnt be as bad as it is. When I run the build if I set it to windowed at 800x600 it is decent with only a little lag in the church yard.

Any advice or more info need to give advice?

If anyone is still having this problem I just finished making my game run smoother by changing my Update functions to contain as little intensive work in them as possible. Here's what I mean, let's say that you control your character's inputs through the update function. If you ever want to take control away from your character (for a tutorial or cutscene for example) it might seem reasonable to set up a boolean canPlayerMove and set it to true or false depending on the situation. Your script would look something like this:

     void FixedUpdate () {
         if (canPlayerMove = true) {
             if(Input.GetKey (KeyCode.A)) {
                 transform.position += Vector3.left * movementSpeed * Time.deltaTime;
             } else if (Input.GetKey (KeyCode.D)) {
                 transform.position += Vector3.right * movementSpeed * Time.deltaTime;
             }
         }
     }
 
     // This function let's the player move
     public void PlayerStart () {
         canPlayerMove = true;
     }
 
     // This function prevents the player from moving
     public void PlayerStop () {
         canPlayerMove = false;
     }

However, now your Update method is checking whether or not canPlayerMove is true every single frame. Stuff like this is what will lag your game, so finding creative solutions to these types of problems is going to be what helps you. A solution to this problem might be turning the canPlayerMove boolean into an integer that is either 1 or 0 and multiply it to the transform.position. Here's what that would look like:

     void FixedUpdate () {
         if(Input.GetKey (KeyCode.A)) {
             transform.position += Vector3.left * movementSpeed * Time.deltaTime * canPlayerMove;
         } else if (Input.GetKey (KeyCode.D)) {
             transform.position += Vector3.right * movementSpeed * Time.deltaTime * canPlayerMove;
         }
     }
 
     // This function let's the player move
     public void PlayerStart () {
         canPlayerMove = 1;
     }
 
     // This function prevents the player from moving
     public void PlayerStop () {
         canPlayerMove = 0;
     }
 
 }

The resulting code is functionally the same, but now you are checking for less things and your game would run more smoothly. I hope this helps if anyone needs it.

PS: This theoretical setup I explained was actually something in my game and after making these changes it heavily improved the performance.

me i lag and i have just 3 house with a road and in the stats its write i do 117 FPS but i feels the lag
