Works with both the Oculus shop and Steam VR. Quite comfortable attached to the head/face, not heavy. Some light gets in near the nose area though (maybe it's adjustable - didn't check yet).
As for the VR itself - expect blurry fonts and maybe very slight motion sickness (but it's waaaay better than it was with Oculus Rift DK1) - depends on the person. The 3D itself in games gives a really nice and immersive feeling though!
The resolution is OK, but nothing more (8K might solve this, but we're not there yet) - don't expect to use it for work (infinite desktop? not there yet)
Has weird problems with stability, at least with my setup (which actually works well for everything else).
Some problems I had:
1) My USB 3.0 was "incompatible" with the sensor.
I had to buy a PCI-e USB 3.0 card for ~25 CHF - this solved the problem.
2) USB device was disconnecting at random moments.
Turing off all USB power saving options I could find helped a little. I think it still is sometimes happening, but very rarely.
3) The software/games are not stable - they crash, I have to manually kill oculus software / restart it to make it work. It does work in the end, but...
No good solution - hopefully will be fixed in future software updates (?).
4) For some reason Oculus says that my PC is not meeting the requirements ^_-
(my setup actually exceeds the recommended one quite a bit)
As a player myself, not sure I would recommend buying unless you're a VR enthusiast. Maybe next generation ;)
Still 4/5 stars, as this is more or less what I expected. … more
