Discussion Unity 5 to Unity 2024 android performance tips

For what concern the shadows, isn't better to bake all the shadows for static objects?

 

1.Baking some objects like trees are not possible and the quality is too low
2.Game apk size will be larger
3. Realtime lights are more alive and shaders can have more properties
4. Day time cycle
5. I have a realtime terrain deformation system. Baked lighting can not be used because the holes must has shadows to be visible

 

Even for large environment? I have a 3x3 km outdoor off road environment where I planned to bake all lights for static objects.

 

Shadows are depending on the distance of the shadows and the how many objects that has shadows

note 1 : change shadow distance from URP asset
or from Edit->Quality settings for built-in pipeline)

note 2 : Disable cast shadows for non important models from mesh renderer component

note 3 : Cull shadows for far and small objects using this class

note 4 : Use shadow cascades method

 

Soft shadows in high quality and distance 210 (URP high preset) :
25% performance cost

Post Effects (tonemapping, Color adjustment, lift gamma gain, Vignette):
20% performance cost

Bloom:
2~3% performance cost

So:
When you turn on Shadows, your 30 fps will be ~23 fps
When you turn on Color Grading, your 30 fps will be ~24 fps
When you turn on Bloom, your 30 fps will be ~29 fps
When you turn on all effects , your 30 fps will be ~17 fps
When you turn on all effects on 50% resolution scale, you will get 30fps

Target test device: Redmi 9A (100$ ~ 150$ phone) at native resolution
RAM: 2gb GPU: PowerVR GE8320

When you use the 50% of the resolution density, your fps will be 30 fps...
So the best way to optimize game is using lower resolution

Also i am working to upload a quality choose toolkit for free on the asset store

Download and test the Demo APK on your own device

 

mmmh not sure I got why you dont suggest baking lights.. the only drawback I see is increase apk size.

 

I Suggest the both... As i said you can use realtime light(only sun light) for some purposes as i said above

As i said, my deformation system needs the realtime lighting to be visible

 

Baked Lighting vs Realtime Lighting with shadows
Redmi 9A in the built-in pipeline:
Note: low fps is result of the 700.000 triangles. Your game must has less than 100.000 triangles for mobile platforms



Gif Comparison:

 

So baked version is almost 50% faster than the real-time version

 

Game Quality Settings for built-in pipeline:

Download From Asset Store

Game Quality Settings for URP pipeline:

Download From Asset Store

Note: Target is mobile devices

Note: You must import post processing from package manager for built-in pipeline​

@UnityLighting hi, why soft shadows not working in mobile, i need this because, hard shadows at low resolution looks pixelated.
And why post processing - ambient occlusion not working in mobile but works in editor (built-in pipeline)

 

hi, just ell me the device model

 

Infinix hot 8

 

Use quality selector and try the settings to find that which effect is not compatible with your device

Also try the URP shadows on your device on the Quality Selection sample

Also try my Built-In APK
and URP APK

 

Thank you bro

As this post comes first in the google search under "Optimize for mobile".

This thread is very educational on its own ++

would like to add:
Unity's official blog on this topic, it also provides an even more detailed free e-book on the topic.

I wish I found it many hours ago, hope this helps someone.

+ I recommend this free FPS counter

It seems like Screen.resolutions doesn't function on android devices. What's the best practice for deciding on a list of acceptable resolutions to present to players? Should we just generate a list based on the Display.main.systemWidth/height. 90, 80, 70, etc percent of normal? Is there a better way?

 

I have a solution in my Quality Selection tools
First save the original screen resolution in the first time running of game (save into the unity's playerprefs)
Then divide it into the 1.0 , 0.7 , 0.5 , 0.3

 

If I understood correctly, you are using a combination of the code mentioned in the first posts (the one with setting the resolution to a lower one), AND setting the Render Scale to some value below 1.0?

Would my mobile game's performance benefit from a combination of these two, or do they actually do the same thing?

 

I just reduce the render scale by my own code. This makes your game playable on any device

 

Sounds good, thanks for answering. Also, congratulations and thank you for the extremely useful tips in this topic!

 

Hey @UnityLighting , Isnt there any other solution to bake normal and oc into albedo map without using Photoshop?... any free tool or something?

 

I was thinking if you could share the code or tell...how are you rendering at 0.5 or 0.7 of native resolution

 

The best and easy to use LOD Maker is the Unreal Engine's model viewer...

Tested on the UE 4.026 and UE 5.0.3
