Hi,

I have tested cop pyro. It is very fast.
But the GPU memory not to be released when jumped off cop module or reset cop simulation.
How to release GPU memory for cop?

Thanks!

I got the answer that Window > Cache manager.

Disable the "Show node preview" under "View" menu can help on that.

What is weird is that VRAM rise up as if it was caching when i play the timebar with a cop network even if their is no simulation involved. and then it stay high even if i clear the Cache using cache manager or enter copcache -c in the textport as specified in the copernicus tip. if i do it longer and it rise at top of VRAM , i see the standard RAM increase and it can lead to a crash...
The only way to clear the VRAM is to exit Houdini
i hope it's a bug and will be fixed because i never had those problem with Houdini 20.5

This issue was fixed in version 21.0.471

I can confirm it works perfect with build 21.0.471
GPU memory doesn't increase like crazy now
Thank you Sidefx dev ! ❤️
