So far, I'm not impressed with their Chronos AI interpolation model.
I'm seeing more image fidelity loss on the big picture, not to mention the much longer render times. The only thing I can say good about it is that you have more framerate options, but anything but whole number multipliers makes for uneven framerate degradation that's producing below-expectation results. Especially at 4k and above. It behaves like RIFE with Motion Smoothing always enabled, so sometimes quick motion seems less jumpy and synthetic in appearance, but blurred in the interstitial frames.
If they can combine the Artemis enhancement models with a viable version of Chronos so it's just 1 process, not two steps, it might become more attractive. But for now I'll stick to RIFE for the more consistent results and far better rendering speed.
