You make a very good point about cutscenes. I'd love if there there was a frame gen & upscaler that exclusively worked on pre-rendered cutscenes to fix the issues in older games of cutscenes looking way worse than gameplay. I know for popular titles, there are sometimes mods that replace the cutscenes videos with upscaled versions, not having to fuss around with that could be really neat. But for gameplay, I'd much rather play at even 50fps native with variable refresh, without artifacts or additional latency, than a faked 120fps that still runs at 60hz of latency with added artifacting.
