Updated to 2019.4.5f1 last week and noticed very bad performance - after a bit of profiling I noticed that it was the URP rendering causing the issues.
Looked into it further and realised that the game view was always double the height and double the width of the resolution of the headset. We are running single pass instanced in the project.
Tried updating steamvr, URP but the issue still remains - seems like the resolution is being squared when it should be just doubled for single pass? Or maybe it’s x4 as I dont see the double view in the game view
