After migrating to DSM7 on DS920+ is VaapiDriver="i965" still needed?

I made this change some time ago because of 4k transcoding problem following this post.

I did the DSM7 install with Plex migration this week and remembered today that I made this change to the Preferences.xml

I understand this problem is now fixed, so I was surprised to see VaapiDriver=“i965” still present.

Is this a remnant of my old Plex on DSM6 or is it normal that it’s still here ?

Best regards
