Proving a negative, eh? Good luck with that. But I'm sure with a carefully chosen game, a carefully chosen setup, and a carefully chosen independent benchmarker, then it won't have any problems.
Besides which, if we're linking PCGamer, here's their Resi 8 Village comparison between the Denuvo and the cracked version, showing the Denuvo version stuttering like crazy compared to the butter smooth cracked version. Probably the same maximum framerate and the same median framerate, and I wouldn't be shocked if the cracked version had a stutter in it, so the minimum framerate would be the same too.
