One could blame the user for not "just" holding it right. Or alternatively reconsider if the handle should have a grippy coating instead.
I haven't seen their documentation, maybe the problem lies there. But there's no tool or documentation so perfect that nobody can use it wrong.
Someone else mentioned GTA getting more aggressive copy protection out of nowhere. It's not out of nowhere. With GTA6 ads out for a while, sales of GTA5 are up as people either play it for the first time or replay it. Sales going up means they can justify copy protection.
Denuvo has layers upon layers of obfuscation that inflates nearly every instruction and function call, extra code execution that does nothing to throw off someone trying to follow code execution paths, and constant moving around where the game stores stuff in memory, again, to throw someone off watching via debugger.
It's pathetic because one company has been almost entirely responsible for people needing to buy faster and faster CPUs and GPUs trying to eek out more and more performance. CPUs, GPUs, memory - all of it has gotten enormously faster, we have more cores, etc. Despite all that, every new game barely runs at 60fps.
Do you really believe that year after year game developers and game engines get worse and worse at performance? Of course not.
If you strictly want to blame Denuvo then that assumes game developers cannot think of a way to spend their extra performance either. Which is obviously not the case.
How does that justify it? Adding stronger DRM when cracked copies of the same content are already out there is like trying to get insurance after your house has already burnt down.
Thus, I believe the poor implementations are directly the fault of Denuvo.
If you compare a game that's had significant performance patches over a period of years and had Denuvo removed to the launch version (as so many of these videos are) then no shit you see performance differences, but it doesn't tell you anything.
This channel has many comparison videos like this one.
Loading times and 1% or 0.1% low FPS are usually hit the hardest and those stutters are the most immersion-breaking.
