Unity build laggy

Unity Engine
1

First of all I hope this is the right forum for my question.

Inside Unity i’m busy with making a environment with some buildings.
It’s a small environment, so something like a really small game (where u can’t do anything ;))

When I try to start my “build” (Standalone) Unity have a really long loading time and it’s laggy (even on low quality). Currently i’m working on a HP ZBook 17 G3 with 32 GB RAM, Intel(R) Core™ i7-6820HQ CPU @ 2,70GHz, 2712 MHz, 4 Core.

How can i fix this? I think my pc has enough power but also I wanna play the build on some slower pc’s or laptops. On those pc’s the build has to load like 5 minutes. This way i can’t use it in a presentation for my company or anything.

So many big games build inside Unity and they perform with high quality so i dont understand why my small environment doesn’t work smooth.

Hope someone can help me with this. Thanks

Something is really wrong then! Builds are typically quicker than the editor for me. You should try making the builds in development mode (there is checkbox as you build them to be debug/developer but I forget the real term).

Then ensure auto connect profiler is checked, it should then bring up the profiler window when you open the build so you can debug why its running so slow

Also do you have same quality settings on editor and in build?
Or maybe its not using the proper gpu when running the app?

I tried make the build in Development mode but it’s still the same, laggy.
I’m really a beginner with Unity but I would love to learn it.

Is it possible the problem is with mesh colliders? i use them on all object and maybe they are into eachother?
The profiler shows the PostLateUpdate.FinishFrameRendering as very high is that normal?

Its your water that is chewing up your processing :slight_smile: If you disable it then your builds should be back to 60fps (looked happy to sit at 60 the rest of the time).

If that works worth looking at your water and figuring out why its so expensive!

I thought hiding the water was enough but it seems I have to delete it. Now is works fine thanks

No worries! Water doesn’t need to be THAT expensive so something is Very wrong there. There are plenty of packs of water on the asset store, I think some are free, that should give you decent water without that horrible FPS

Awesome I’ll look for that in the store. Before I used the standard DayTimeWater from the standardassets.
