After update to 25.4 I have real trouble with rendering simple composition in my project. What was done in seconds, with new version takes tens of minutes..
In the composition are layers with different blend modes, all revealed by animated mask.
Cache cleared, restart AE, restart of computer, updates.. all done..
The slowdown is really extreme. One frame lasts about minute or more. There are few layers with color burn mode, which takes ages to render ATM..
I can post the project.
AE25.4 @ Windows 10, 16 core AMD and nVidia 12GB, 128GB RAM. GPU acceleration enabled..
