my game lags after i build it but smooth when in editor

Hello everyone. I'm currently having an issue i dont have any idea why. First of all, my game has a lot of trees and buildings. i tested in my editor and i got like 80FPS while walking around. but when i build and run it, i got like 15 fps straight away. i tried disabling my scripts but there are no improvements. i used lightmaps, ambience occlusion but no improvement in fps. Hope to get some help here

Below is my game preview screenshot.

My specs :

I7-6700HQ
Nvidia GTX960m
16GB DDR4

 

Try using the profiler in the editor, it will show you whats slowing your game down. I suspect its the trees, maybe use more LOD, texture atlasing, ect.?

A side note: it looks really cool, what kind of game are you making?

 

That's the first thing I thought as well, BUT - he said it's smooth in the Editor.
So not sure if that's going to help too much.

 

Yes, but it should still show whats eating up the resources.

 

thanks my friend. I'm currently making a medieval type of game. interact with ai and follow stories, do mission and gain money, not only do mission, perhaps you can farm, own a house and a pet like horse, pig etc.. but that will be future maybe. as for now, need to sort out the village done. Everything you see here is all freewre from the assets store. Working alone on this

Btw, this is my profiler

 

The overview (scroll down a bit) and the CPU usage (scroll up a bit) are what you should look at, generally these have the culprits. Also, what's your draw calls in the scene?

 

Here you go..

 

It's pretty simple, you could just read it yourself. Then let us know the possible culprits.

It looks like it's the rendering. What are you draw culls? (Click the rendering, then look down in the description box).

 

I have little background on this game development btw. Thanks for helping me out

Draw calls is between 2K to 4K.

 

Maybe your game view window is much smaller in the Editor than in the build? If so the build might be slower since there are more pixels to render. Also try disabling vsync. That might further affect the frame rate in the build.

 

how do i disable the vsync?

 

Yeah, no problem, I just figured its easier for you if you tell me the stuff that looks craziest, as there are alot of panels in the profiler and it could be a pain to upload all the images.

Yep, thats most likely the problem, it could definitely be a bottleneck. Just for some perspective a mobile game is normally under 160, so 2k-4k is quite a bit more. Take a look at this, it has some references that should help you understand and reduce the amount of draw culls. Now this all depends on your graphics card (and that of your target audience) but you should be able to get it sub 500 without too much hassle.

 

When you google "unity how do i disable the vsync" it's the first result.


To reduce drawcalls check this:
https://docs.unity3d.com/Manual/DrawCallBatching.html

And learn about light baking and deferred vs forward rendering, and see if you can build a lighting/rendering setup that performs better. It's not an easy to answer question as the topic is quite deep and we don't know all the details of your project. E.g. if the houses are made up of dozens of individual objects with 3 different materials each, not set to static, and you have many dynamic light sources, that could be a big part of the problem.

 

What is the build... desktop, web, mobile, TV? Didn't notice any info on this. If someone already asked and I missed it sorry about that. If it is working awesome in the editor and not on the target build that makes me think possibly you are targeting web or mobile or something else besides desktop.

Also keep in mind you really can't go by what the FPS shows in the Editor. If that is all you are going by then disregard it. If you are saying the game truly lags (you can see the lag, feel the lag) that is different.

 

This may be an obvious question, but is it perchance on a higher quality setting when you run the build?

 

You could also check to see if "anti-aliasing" is the culprit in your quality settings. Lots of times in my games, anti-aliasing is terrible for performance, especially with a lot of trees. I'm just guessing though, and trying to put some ideas out there. Profiling your built-game is probably the only way to see exactly what it is though.

 

When you leave build mode, click save and it should go away. Doing this has always worked for me.
