AQUIRIS, 12 YEARS
Founded in 2007, the studio has a team of around

or co-developing games with top notch global publishers.

Co-development Proprietary IPs
AQUIRIS has two studios located in Porto Alegre, south of Brazil, inside
a tech park called TecnoPUC, alongside of an University with great

16. Memory optimization
16

17. ● Not unloading assets
● Duplicated assets loaded
● Texture size and compression
● Quality Settings
Common problems
17

18. 24MB of textures not unloaded
18

19. Duplicated textures

22. First Time User Experience
22

23. PvP Battles
23

24. ● Focus on early game features (product KPIs)
● Find the best compression for the platform
○ Android:
■ RGB: ETC Crunched (50% Quality)
■ RGBA: ETC2 Compressed e ASTC 6x6
○ iOS:
■ RGB e RGBA: ASTC 6x6
● Budget for assets (memory, file size, draw calls)
● Cache pool (even for Lists, Dictionaries, and so on)
More optimizations
24

25. CPU optimization
25

26. ● Frameworks and APIs
● Loading too many objects in one frame
● Not caching variables and data
● Large scenes with many objects
Common problems
26

27. ● Do not use
○ Find()
○ FindWithTag()
○ FindGameObjectsWithTag()
Frameworks and APIs
● Avoid using
○ LINQ
○ Awake()
○ GetComponent()
○ SetActive()
27

28. Character collection load is distributed between 22 frames.
Loading too many objects in one frame
28

29. Not caching variables and data
29
Loading characters data from data provider

30. Not caching variables and data
30
Caching its data

31. Large scenes with many objects
31

32. ● Keep draw calls at a lower rate
● Use threads for parallel operations (Coroutines run in the main thread)
● Keep the class constructor simple
● Review the third party plugins performance as well
32
More optimizations

33. Best practices for
mobile games
33

34. ● Always use the profiler to validate you hypothesis
● Profiling on Unity Editor is different than profiling on mobile devices
● Collect metrics to analyse and compare with previous data
● Prioritize the test on low end devices
● Avoid early optimizations
