VR performance downgrades

[languid harness]

Unity 2022+ have huge downgrades in performance. 2021.3 vs 2023.1 is a 50% decrease in performance for standalone VR. The GPU is just being hit a lot harder.

Already looked into many depth prepass options etc, but there is no fix working right now (except porting older URP versions to later unity version, which isn't optimal.

Is there any way to work around this or any idea on fixes?

Already have a bug report out, but vr performance reports take months to be processed by QA: IN-31610

Hi Dev Dunk! I'm asking our URP team about this, hopefully I'll be able to get back to you with something!

I've heard back from them and spoken to our QA team. We're looking to expedite reproducing your bug and the URP team will take a look at it once it's landed with them.
We are aware that there are performance differences with URP between different Unity versions. A lot of features were added in 2021, some of which are enabled by default when upgrading which could be leading to the extra cost. Once the team have your bug they'll look into exactly what's causing the problem. Sorry we haven't gotten you a more concrete answer right now but hopefully we'll get there soon!

@dawn apex can we have the list of feature added in 2021 that are on by default and could potentially cause performance drop?

Can official properly solve this issue at unity 2023.2 cycle after adding a lot of features? Consider make it like post processing that has the feature list able to toggle on/off the feature that u really want and dun want

Thanks!
2021.3 lts is alright now (3-10% lower than 2020.3 still, but better than before).
It also happens in blank 2022+ projects, even when optimizing the settings

I have asked the team if this we already have these settings as a list somewhere, we'll see what they say. Hopefully that'll help track down what's causing these issues! 🤞
