Dynamic resolution with STP does not work in VR anymore in 6000.0.41 (compared to e.g. 6000.0.35, were it worked perfectly).
Shadows were broken for 5-6 releases. APV also. I think both fixed now.
In DX12, we are getting thousands of warnings about “attempting to draw with missing bindings” on several materials, which leads to Unity Editor crashing at some point.
Performance in DX12 is getting worse and worse the longer you work with the Editor. For us, DX12 is pretty much unusable, but it comes now as default, and some newer features only work with DX12 (e.g. foveated rendering)
We are hard trying to migrate our project (HDRP + VR) to Unity 6 (from 2023.2.20), but encounter these severe bugs in doing so.
For VR to be usable in VR we need to be able to use dynamic resolution, which worked fine until 2023.2.20. DLSS still works to some extend in Unity6, but with bugs I reported.
I usually hate it when others just rant about something, but this situation really becomes severe for our company.
I hardly advise you to refrain from using HDRP with DX12 under any circumstances, their implementation of dx12 in the engine is still almost as bad as 5 years ago. Unity dx11 implementation is still much better by a long shot, unfortunately.
The issue is that some features like ray tracing require DX12. The ray tracing implementation seems quite good + performant if DX12 runs smooth (which seems to happen sometimes). And as I said newer features need DX12, too: Foveated rendering for example.
So I see a high demand that DX12 gets fixed. It already got better in Unity6 vs 2022 LTS, but there is much stuff left to do, and probably the priority right now is not high enough.
You’re right, just tested turning dx12 with split graphics jobs on my project (6000.1.0b10) and as a big surprise the performance is almost identical as dx11!
Happy to see that as I always wanted to try out the raytracing/other features but basic performance diff was always abysmal…
But yeah bummer to see those LTS releases full of problems, incredibly frustrating 'cause it’s always something major and very important
