I’m not sure if this is a bug, but there has been some kind of change in the way manipulation evaluates in Maya 2020.1-2020.2
2018 - it’s all good
2020.0 - still good
2020.1 - laggy manipulation
2020.2 - same as 2020.1
Maya 2018. The EM state is ready. About 22 fps.
Maya 2020.2. I also made sure the EM state was ready. About 4 fps.
I’ve noticed I can recreate the same behavior in 2018 if I disable manipulation from the evaluation.
In 2020 there seem to be some new settings. I’ve tried all of them and nothing changed. Playback performance is unaffected though. I’ve had much better playback speeds in 2020 with and without cache. I’ve also tried other rigs. The performance gap is not as bad as compared to this rig, but it still manipulates slower in 2020.1 and 2020.2. I’m curious if anyone else has noticed this behavior.
