Yup… I originally noticed this around Preview 6 for 4.26 the first couple of preview releases didn’t really show any changes in performance and then boom 20pfps gone. I hoped that it was something that would be fixed in the final release
I did some basic tests and the default map is running 1ms slower while the more complex projects have seen increases in the likes of 4-5ms.
Will try and dig a bit deeper once I have more time for now I’m sticking with 4.25 until I wrap up some work
