Future version 8.5 will bring significant improvement for AV authors who create heavy animation with a lot of keyframes. For example, I compared a work of Rubik demo by Jean-Cyprien in v8.0 and future v8.5. Size of .pte project file is 14 MB (509'343 lines). 1. Time to load the project. Almost in 2x faster in v8.5 than in v8.0 2. Memory usage. v8.0 - 640 MB of system memory. New v8.5 - 353 MB. Almost in 2x less memory usage. That's not all, due to the new architecture of keyframes the final version 8.5 will consume even less system memory. Memory usage was reduced after deep optimization of work with .pte project in memory.
