It's easy to think of an update that's turning-oriented as boring or insubstantial. But, in virtual reality, the locomotion of your character (and, hopefully, how it keeps you from feeling sick) is super important.
That's the main focus of Half-Life: Alyx's version 1.1 update. You'll be able to turn better and that should go quite a ways as a quality of life improvement. For people who play on the first-person shooter-style continuous motion setting (that is to say not teleporting around), there's a new option for fluid, continuous turns without a snap effect. Likewise, there are different speed settings for continuous turn.
This seemingly doubles as a bug fix of sorts because using continuous motion and disabling quick turn didn't actually work at launch. Now, people will have more options for whatever makes them most comfortable. Again, that's paramount with VR.
