I purchased this game on sale at GOG.com a while back (2014?) when I was exited about the Linux port, and before I realized it used the wrapper eON translation layer. (We can quibble over wrapper vs API vs etc here: PSA: eON is not a wrapper).
I'll just say that native linux code would be better.
Performance with Slackware64 multilib with Nvidia GTX 660 was poor: crashes, video glitches, lags, sudden fps drops. I was barely able to complete the tutorial section. A few patches were released that improved performance. There was also github project that tracked Linux updates and performance tweaks which now seems to be gone. I put the game aside for awhile to let it mature.
GOG.com updated Witcher 2 to Release 3, and it is officially tested on Ubuntu 16.04 LTS, Ubuntu 18.04 LTS, and variants. Non-Ubuntu Linux distributions are not officially supported - as in no technical support or refund. As a Slackware user, I have found that par for the course. Here are some notes on giving Witcher 2 another go.
