Frame interpolation with GPU

Custom Nodes

HI GUYS, im new here and im’ playing with comfyui since just few months so please don’t blame me if i’m telling something completely wrong.
my question is this:

i’m struggling with a custom workflow of wan 2.2 i made because of frame interpolation, i have a quite nice video card and i don’t like that almost half the time i need to generate a video is always due to frame interpolation. im using vfi rife 49 custom node to do that and im using crystools to see where the system stucks and i noticed that frame interpolation is ALL CPU charged and my GPU is not working at all in this step. i tried something i found online and tried ask chatgpt what could i do to move the job from CPU to GPU so it should be really faster but i didn’t achieve nothing.

can someone help me please? :slight_smile:

usually rife goes crazy fast, if you didn’t set it specifically oj cpu, maybe the batch it’s trying to “rife” is on the cpu, check the nodes that come before

i tried everything, now the only nodes that comes before RIFE are KSampler and VAE decode, then straight to the interpolation but it requires almost 1 minute to interpolate 100 frames, i think it can be improved, or maybe im wrong?
