hello forum i make gpu process for desinterleave a camera flow and then make some matrix operation, but after testing framerate with a fullHD interlaced grabbing, i just wonder why jit.gl.node @capture 1 is slower than jit.gl.asyncread even if it is newer ?

the battle patch : more than 25fps difference should i do something else with node, or asyncread is definitely better ? why does asyncread must be in interleaved mode, does that change the quality ? thanks
