Nice! Need more videos like this from unity, also with much more deep explanation / examples / techniques.

Great Talk! Thanks.

great talk.
1. Auditor should be mensioned in offical manual about shader prewarming in android subcategory
2. more info abount Untracked memory from native profilers stacktraces is very important and usefull
3. new Shader chunk loading need more details in manual page about drawback mesnioned in video (about low chunk -> slower compilation, cause by disk load)
4. using native collections in main-thread should be on slide
5. memory fragmentation need more built in profiling tools, or more info in manual, if they're there already. We can't understand, is memory fragmented or not. Or is it reason for memory crash or not
