My favourite tool is GPU Screen Recorder - https://git.dec05eba.com/gpu-screen-recorder/about/
This is a screen recorder that has minimal impact on system performance by recording your monitor using the GPU only, similar to shadowplay on windows. This is the fastest screen recording tool for Linux.
It works with AMD, Intel and Nvidia GPUs. It is also the one that performs better. Official repos AUR or Flatpak, or you can install from the source above. The flatpak already comes with the UI gtk https://git.dec05eba.com/gpu-screen-recorder-gtk/
Other tools I used were OBS and Steam - you can enable Steam to record your games in the Settings > Game Recording > Record in Background
OBS was very laggy for me.
Those metrics are bollocks.
For Denuvo, you don’t need their data. Plenty of games let you play a week before release, then add Denuvo, wait a few months, then remove. During Denuvo days, there is a flood of poor reviews associated with performance.
For the 20%, they just invented a number, there is no real base for that, at least not a solid one. I wonder if Denuvo takes in account the number of games returned because of them.
A long time ago, a game distributor was a guest lecturer to a class I was taking, and I learned a bunch there. For piracy, it seems that their company navigate the seven seas to count downloads and estimate black market sales, multiply by the game price, and assume that was lost revenue caused by piracy. It was very weird, as some games piracy numbers were 100 times bigger than the amount sold and sounded like they were losing billions of dollars in revenue per game because of that. I asked if they really think they would sell that number of games if there was no piracy, if the people pirating games would buy/could afford the full price they took in account - they went from a well-formed teacher to straight red face mouth foaming dogma discourse. There is a lot of money in DRM, and it seems they want to keep that way with doctrine and/or bribery.
For the class, we (students) had to do a market research, and of our small reach (local game forums, malls and where people buy pirated CDs - this was a long time ago), we did not meet a single person self identified as pirate, who would buy a game they want to play if the pirated version was not available, either free from web or street vendors, they would just play something else they could find and afford. That did not bode well with the guest lecturer, but a lot of our findings about piracy narrowed it down to availability, price and convenience - well, there was a minor percentage of people that would always and only pirate for the most diverse reasons even if they could afford the game.
