I responded to this in the discord, but I will post this here as well so people are aware (who are not part of the discord).
This is not a feature Hive is opting out of displaying.
This is an issue with Nvidia’s driver limitations, and the fact that the drivers do not expose memory / junction temperatures. It is something being worked on, but right now it’s simply not possible to be displayed due to the fact that the driver doesn’t display the temperature within Linux.
Yes, it works in Windows, because they are two separate operating systems and not at all related.
I have brought this up to the dev that I have contact with (I am a moderator on the discord and one of the more active community members on said support channel) on a couple of different occasions, and both have resulted in the same answer. It’s something that is difficult to get to display accurately, but it is something being worked on.
