So I started a new mobile project in 2020.1 with Universal RP. While prototyping and setting up basic systems I did my first build and deployed to mobile. I was very disappointed when almost an empty scene with very basic post processing (just a color lookup) couldn't keep 60 fps on mobile. My previous project could run at 60fps with post processing so I decided to investigate. It turns out that the performance was going downhill since Post Processing Stack V2 was introduced. I've tested these scenarios: 1. Unity 2018.4.3f1 built-in renderer: - Standard shader - Standard + Post Processing Stack V1 - Standard + Post Processing Stack V2 - Mobile Bumped Diffuse - Mobile Bumped Diffuse + Post Processing Stack V1 - Mobile Bumped Diffuse + Post Processing Stack V2 2. Unity 2020.1.0a13 built-in renderer: - Standard shader - Standard + Post Processing Stack V1 - Standard + Post Processing Stack V2 - Mobile Bumped Diffuse - Mobile Bumped Diffuse + Post Processing Stack V1 - Mobile Bumped Diffuse + Post Processing Stack V2 3. Unity 2020.1.0a13 Universal Render Pipeline with built-in Post Processing - Lit - Lit + Post Processing enabled - Simple Lit - Simple Lit + Post Processing enabled Test scene looks like this: I tried to keep the quality and player settings as close as possible between projects. All materials use Diffuse + Normal maps. All PostProcessing profiles are only using a 16 LUT for color grading (StackV2 and URP versions set to Low Definition Range). I've run the tests on Xiaomi Mi A1, and I've also checked on Nokia 6.1. The results were basically the same: Oldest Unity 2018 works best with oldest Post Processing Stack V1. Switching to Post Processing Stack V2 results in FPS dropping by 10-15 (below 60). Unity 2020.1 is visibly slower than 2018 using any Post Processing. I assume that a bit more complex scene, and it will be visibly slower without Post Processing as well. Unity 2020.1 with URP and built-in Post Processing is the worst. Wasn't URP supposed to have like better performance than everything else? How come that a 2-3 year old Unity runs better on mobile than anything currently does? What's up with PP Stack V2 being so much worse than PP Stack V1? How come I can't run the simplest scene with the simplest color grading at 60 fps on mobile? I have so many questions and so much frustration... What's going on?
