Fuse framerate drop

Hi, I’m creating a patch based on the use texture renderer fuse patch and Im having issues with the framerate. It starts at 60 and after some minutes it begins to fall until reaching about10fps. I tried many thing but couldnt solve it. I tried in other machines as well and the problem is the same.
fuse 1.0.3-bet06
vvvv 6.7

Post your patch or a simplified version that demonstrates the issue. Otherwise it’s impossible to tell what’s going on.

The original patch is ‘Reference Use TextureRenderer’, an example of FUSE library
The problem happens after a few minutes. The animation goes from 60 fps to about 10 after one hour

this is the patch:
respiro_23_DEBUG.vl (207.2 KB)
I made a on/off button to try to keep the framerate, but it dosn’t work…
