I'm rather surprised this worked on my system. My gaming PC is an MSI GL63-series laptop with a Geforce 1660 TI Mobile graphics card. Not exactly the Lambo of gaming laptops or graphics, but it handles well enough for every game I've put it up against.
All the 'DisplayPort needed' talk made me wiggle too, but an MDP-to-DP adapter make it work perfectly. (Heck, it came with one in the packaging, too)
Pros:
So far, games work just fine on mediumish quality with little to no lag issues. I play Half Life: Alyx on Medium and it works very well, Beat Sabre give no trouble, and VRchat also operated quite well. The room-tracking actually impressed me, it was quite near 1:1 movement with maybe 2-15 ms delay at worst and that was because of the laptop most likely. It presented an appropriate sense of scale within applications, as well as ample crouch detection, which you need for some games behind cover!
The button configuration works well enough for all apps since SteamVR is handling most of the input mappings to known VR systems I suppose. Sure, it doesn't have a hand strap like the Index... so I use the wrist straps and don't drop my controllers. I don't hand per-finger tracking, but I got grips, and the interfaces are fine with that. Sure, I popped extra for the room sensors, it made logical sense so my clumsy self won't bump into the TV or couch.
Cons:
The cable can bunch up a bit after a few dozen turns around the room, I'll attest to that. Sort of wish the earphones would better press to my ears, but I can hear through them fine while they hover just a half-inch away from my ears. Wouldn't've minded a 3.5mm plug to auxiliary headphones. Mic works in VRchat clearly however.
Maybe this is just me still finding my VR legs, but after a few hours of usage, I do notice a 'tactile disparity' with the real world the next day. It's gotten better, probably need to tune that side eye-spacing knob a little better. But that knob ain't great and I can't go below 60mm which might help some smaller folk.
Sure I had to make a Vive account during setup but... at least it ain't hocking my personal information or locking my games to a Meta account like some VR solutions might be doing. I don't HAVE to use the Vive storefront; SteamVR interfaces with it just fine. In fact, it's what does the actual room setup.
Summary:
I mean, sure the Index would be baller, but some of us have more important things like... you know... rent or groceries or bills. Do you NEED a $1,000+ VR setup? ... I mean REALLY NEED it? Do you need a $1,000+ phone? I mean REALLY NEED it? Do you NEED a car with power windows or can you just use the hand crank to achieve the same outcome and save a couple hundred bucks?
Moderation in all things; the middle option is oftentimes sufficient. The HTC Cosmos Elite is plenty sufficient for its intended use case scenarios.
