PostProcessing v2 PostProcessLayer performance consideration

Unity Engine
1

Hello.

Today I decided to add PP v2 for our mobile project and was surprised that simply by having active PostProcessLayer on camera FPS dropped from 43+ FPS down to ~28.

Effects itself with activated “Fast Mode” showed quite good results, less then ~3 FPS drop per effect (Color Grading, Vignette, Chromatic Aberration are quite useful not to use them), if only PostProcessLayer haven’t kill all the performance…

So the question is if I missed something and this is not the correct behavior, or this is the fact which I should except for now and live with it?

Sorry for creating separate thread for this, I saw similar question [here]( New Post-processing Stack (Pre-Release) page-19#post-3533027) and somewhere else, but both are without answer.

Thanks in advance!

Hi!
Just a guess: it’s doing a blit even if it doesn’t have any effects enabled, which is costly. Can you please submit a bug report?

Hi, thank you for response!
I’ll prepare lightweight test project with reproduction in the evening, because our real project is quite massive to send it.

I’ve reported a bug, here is a Link.
If you need additional info, I will be glad to provide it.
I profiled Xiaomi Redmi 3, but we experienced same behaviour on Xiaomi Redmi 4, Meizu M3 and other devices.
