Hi, I created a small game for mobile and added some post-processing effects (chromatic aberration, lens distortion, grain) but in runtime, on my phone, it’s too laggy. I searched on the documentation and the LWRP has fast and mobile friendly effects, but now I can only use URP on Unity 2019.3.
My question is what can I do to have better performance on these effects? Should I use another render pipeline or the URP has a trick to fast compute these effects? Thanks
I am using 2019.3 URP but you don’t really provide any information I can use to help you. Consider putting a little more effort into your question if you want help. Everything I am about to say is quite generic because you provide no detail.

- Get rid of chromatic aberration if possible. It’s not mobile-friendly. I believe only Color Grading, Bloom and maybe 2/3 other effects are decent for mobile.
- Write your own renderer. Now that might sound like a lot of work (it can be) but it would allow finer control over your render pipeline if you really want to push post-processing.
- Find out where you need to optimise. You have provided no profiler stats, no frame debug stats… how is anyone supposed to help you with no information? Are you GPU bound? are you 100% sure it’s post-processing causing the issue? etc

Here you can see exactly what is happening for a specific frame.

Here you can see the post-processing effects are taking 0.2 ms.
Thank’s for your quick response, you’re right I provided no details but your answers satisfied me. I’m sure that post-processing is the problem, and maybe the best solution for me is to get rid of the effects.
Anyway thanks for your time.
