Decreasing speed

[Molki]

Hello, 
I am a newbie in tyflow. And did not find a threat about this issue.

I use tyflow (free version) in 3ds max to generate growing ivy. 
I use V-ray to render it, but every frame is slower and slower.
64gbs of RAM, and 3080ti 12gb (2x). The complete scene with tyflow take 4 GB ROM.
How the computer use 20 GB of RAM without tyflow and 30 GB of RAM with tyflow.

To calculate a complete tyflow simulation, it takes about a minute.
Then switching between frames takes like 2 seconds.

Without tyflow, the scene is rendered in 26sec for every frame.
After I turn on Tyflow, it takes 1min, and every next frame is slower. Frame number 375 takes about 5 minutes.

Does the Paid version with cash or multi-thread thread options speed up the process? 

If yes, will there be a memory of GPU issues in large scenes? 

Thank you.

What part of the render processing is it getting stuck on? Are you using VRay CPU or GPU?

There's nothing specific about the free/paid distinction that would cause tyFlow to get slower over time during rendering....
