Maybe it could be nice to start a new thread every time a new UE version is launched so its easy to catch up for everyone.
My observations up to 4.24.0 p2;
+ cascaded shadow maps work again when using MobileMultiView (Quest). In 4.23 the shadows were broken with MMV.
+ UE added automatic instancing for mobile. You enable it by adding 'r.Mobile.SupportGPUScene=1' to the 'DefaultEngine.ini' (Quest). When analyzing your app in Renderdoc it will report the instances but in the TextureViewer the instances will be pitch black (reported to UE). Also, I noticed that the algorithm still misses some objects sometimes (I haven't found any logic yet why some are missed - reported to UE).
+ Vulkan is on par with OGL (in 4.23 I noticed a big fps drop) but the purple glitches are still present sometimes.
+ Oculus SDK will be updated to 1.40.0
- the splash screen is broken (Quest - reported and confirmed by UE).
- strikethrough: fixed in new nightly build of RenderDoc
