Recently I have tested a 4K VR [ probably the only available on the market solution for 4K ],
and opinion/results in shortly:
Pimax-4K-UHD-VR-3D-Headset-7.jpg
Advantages:
- 4K resolution screen
- No SDE [ image is perfectly clear - so can see all cockpit details, colors are more real / natural ]
- Renders in 2.5K and upscale to 4K [ so present GPU`s can manage all rendering with Ultra settings - my GTX1080 ]
- Price [ 200 used, 300-400$ new ]
- Steam VR support [ tested: Project Cars / DCS - works perfect ! had problem with Dirt Rally ]
Disadvantages:
- No positional tracking [ 20$ - solved ]
- 60Hz freq display with bigger latency [ little ghosting on fast moves - but not disturbing ]
Comparision of SCREEN [ HTC Vive / Oculus CV1 / Pimax 4K ]
This Video “talks” more then a thousands of words ! 
Verdict:
It is not perfect, but IMHO worth it !! [ Probably will sell my CV1 pretty soon ]
As a VR CV1, and PSVR user [ Vive only tested for an hour ] with 3 year experience in this matter [ started from a preorder of DK2 kit 3 years ago, then upgraded to a CV1 over year ago ] so generally I used most of them for many many hours and was really waiting for something better after such time…
also for me as I get used to best possible solutions from all VR googles, something like positional tracking is simple a must have and lack of this makes VR totaly pointless [ in a cockpit simulators ] - for a Pimax hopefully it can be added without much efford - as I will write in details [ this PT won`t be as perfect as CV1/Vive, but pretty good ].
Installation:
SW: Pimax PIPlay http://www.pimaxvr.com/download/ - lack of virtual room, only a visible logo of Pimax. It has some demos like video 360, movies VR, and steamVR button so its general purpose is to start the steamVR app !
Issues:
- if already installed Oculus Home [ for a CV1 ] I had some problems, so I simply uninstalled it.
Addons:
- Positional Tracking,
- Option 1: NOLO VR [ 200$ ] https://www.nolovr.com
- Option 2: [ PS Move - 10-20$ solution ]
My 3D printed VR Tracking Ball [ 0.1 layer / 100% infill - had only a yellow PLA ] :

Simple Tutorial of Daley Tech
HW:
-
VR Tracking Ball and mount ( PS Move Service ) - 3D printed [ but can be a pingpong ball or something ] - I used a 12V LED bulb with a 12V power source [ 12V 1A power supply and cable attached directly to bulb ]
VR Tracking Ball and Mount (PS Move Service) by ImpelRacing - Thingiverse -
1-3 PSMove + 1-4 PS3Camera [ I bought 1 camera and 1 move - for about 10$ ]
-
a Bluetooth adapter [ if PC has - OK, if not buy a 5$ one, even if PSMove is connected with cable ]
SW: -
PSMoveServices, or better PSMoveSteamVRBridge [ with SteamVR support ]
Releases · HipsterSloth/PSMoveSteamVRBridge · GitHub
[ it was designed for a move controllers, so you can have 1-2 moves which becames Steam VIVE controller, BUT: wont simple work [ for an HMD tracking ] with a Pimax... mostly used for a phone HMD and with a VRift [ RiftCat combines to Steam and for a Cardboard google, or phone it works, with PIMAX - WONT ! [ hopefully there is a workaround ] -
FreePieConnector - this is the driver needed for a HMD with tracking ball [ or PS move on HMD ] to work with SteamVR - now is called Driver4VR [ demo let you test for 10 minutes / full version costs 8E ] http://www.driver4vr.com
-
PS3 Camera driver [ 4.1) CL-Eye-Driver 4.2) [ Zadig http://zadig.akeo.ie ]
-
FreePie [ actually with SteamVR probably not needed ]
this is first weekend of configuration and playing [ using my 2DOF offcourse ! ] I hope you find it usefull, and thanks for reading !
Best regards
