@Devil_Inside didn’t have time to test 2019.3 or 2020.1
But after more test in 2019.2 I have come to conclusion that LWRP perform well and here is some tips
Don’t use static batching
SRP Batcher help sooooo much for scenes with many draw calls, I’ve been able to run some scenes with more than 1M, more than 2000 draw calls and shadow(only directional light) at 15-20fps@720P
Vulkan is buggy and unstable can’t rely on it
