During 2017.2 beta, we found a performance regression in UGUI.Rendering.UpdateBatches: https://forum.unity.com/threads/ugui-rendering-updatebatches-performance-regression.496849/ I checked this 2017.3.0b6 today. Performance did improve in this area again, awesome! Unfortunately, according to my tests, it continues to be slower than 2017.1.1p2. Code (CSharp): UGUI.Rendering.UpdateBatches 2017.1.1p2 = 0.06ms 2017.3.0b6 = 0.15ms Spoiler: Unity 2017.1.1p2 Spoiler: Unity 2017.3.0b6 The "TransformCangedDispatch" entry in the Profiler has been introduced during 2017.2, perhaps related to the performance regression? Can we expect further fixes or improvements in this area, so that UGUI.Rendering.UpdateBatches is on-par with 2017.1 again?
