When upscaling batches of images it will slowly eat up all my system memory. At some point it will start swapping and then spiral the system into swapping death loop. Usually it happens around 60 - 70 images upscaled.
The behavior can be reproduced.
Using it on Ubuntu 24, RTX 4080, 48 GB RAM

Can the node be updated to have a setting to clear nvvfx's native buffers after so many frames?

I experienced this before with wan2.2. I'm assuming it's still present since there's no recent update
