What exactly did they do here? X linked video is broken for me, and the article just says the performance is bad. My pixel 6 just got Android 14. Possibly just OS/new hardware related?
According to the 3DMark playstore page, the last update was Sept 21, 2023. Version 2.3.4869. Android 14 came out October 4th, making any incompatibility likely a temporary problem.
Unless there's a quote from 3DMark explaining how everything is dandy in their end, I'm not buying what you are selling.
