I had a bit of a mare getting it installed initially. Mainly to do with Kaspersky sticking it's oar in and the Vive software doing lots of system stuff.
Eventually I uninstalled Kaspersky just to get the Vive + SteamVR client installed.
Then still had an issue with SteamVR but basically right click Steam.exe ... run as Administrator fixed that.
OK so first impression is yeah it's limited by the optics and you need to get the headset centered on your eyes as there's quite a small sweet spot to reduce the screen door and god rays (at first I thought there was something on the lens but after wiping realised it was a sort of ghosting affect on certain scenes).
The IPD adjustment didn't do that much and only became blurry for me when adjusted very near together. For the lens distance again I adjusted it as close as poss to my eyes as it widens the FOV and maybe backed it off one step.
The artifacts will always there to be honest but I had several moments, so far mostly in The Lab. When I completely forgot about it and just enjoyed the experience.
The desktop stuff kinda works at certain distances and resolutions and then other times its blurry and unreadable so plenty of playing and tweaking to be done.
The tracking is nigh on perfect but again you can improve things by tweaking the Lighthouses. Basically if you your controllers sit slightly in the floor or you feel the virtual floor isn't flat with the real floor it's the Light house alignment throwing it off.
Oh and they whir in the background when your don't have the HMD on though my very stark room may not be helping that. Some soft furnishing or carpet should reduce it.
My area maps out to 2.7m x 1.9m and that 1.9m is right on the minimum usable space. Basically I kept triggering the Chaperone just by picking up those damn sticks and throwing them.
Yeah I hit the wall once doing that and yeah I poked the ceiling too playing with those purty balloons
Walking into virtual stuff just feels wrong and you naturally avoid doing it. Playing with mundane virtual objects just shouldn't make you smile like a kid it's wrong! Windlands made me feel unsteady on my feet (but not nauseous) when I jumped but that's the only free movement game I've tried so far and only for a few mins.
The cable occasionally breaks the immersion but it quickly becomes a background task that you deal with almost subconsciously.
So on the whole it's a brand new experience with some great moments and some frustration at the current tech.
