Been an issue since v5.4 was released. Proteus and Artemis (as far as i know) drop frames for no reason. If you aren’t using Rhea XL or SDR to HDR models, download v5.3.6 for now. Except for Rhea XL and SDR to HDR it has the same models, but you won’t face any issues with dropped frames.
You can download it here Topaz Video AI 5.3.5 - 5.3.6
