GPU is not fully utilised

[animafps]

There is somewhere in the pipeline that is cpu bottlenecking for most systems

couleur says it might be the blending and can opencl or cuda that part of the process https://github.com/animafps/vs-frameblender-opencl is my attempt but i am not fluent with gpu processing

or can bypass the plugin system and work with the raw video node in rust and opencl that

VapourSynth seems to mostly use CPU, we can offload encoding with hardware acceleration and build GPU accelerated plugins like you did to help strain on CPU 👍👍
