Because it's heavily encrypted. The unpacking process takes a very long time. In many cases, it's better to just download it at release and not have to worry about that.
The requirements are likely based on a 90hz refresh, so you will be fine.
Unpacking the preload usually takes a decent amount of time. Usually 30 min to an hour but sometimes even longer. This game's size isn't that huge so maybe not overly long. But with a decent download speed it's better to just wait to download at release. It'll probably take just 20 minutes for me.
I've encountered the same thing, and think it's mostly to do with how Unity is loading things in, or in instances of the Portal demo, it's handing off to Source 2 I guess. I've also found a lot of success using the Oculus software to add the Steam games as native shortcuts, rather than launching into Steam VR and then launching into a game. I think you have to check a box that allows 'Unknown Sources' or something on the Oculus side, but that helped me out a lot.
Yep some games are too intense. I doubt I'll revisit Gorn because the locomotion makes it harder to keep track of where I am in physical space. I wish the knuckles were more durable. Hopefully I'll be able to RMA after Corona blows over.
In Gorn the locomotion is weird so I lost track of where I was in the physical space. The gameplay can get intense as well. Also my chaperone border is easy to look passed when things are intense (and my playspace is pretty small).
The SteamVR home environment itself ran well. It just seemed to get screwed up temporarily while transitioning from one thing to the other.
