I have jut upgraded from the rift to the Vive pro, I also have a Pimax on the way. Why did I go with a Vive Pro.. Well, I needed the controllers and the Lighthouses for use with the Pimax as their stuff will be a long way away before it is completed and delivered. When ready i will have a 4 lighthouse setup..
The vive pro is awesome for Elite,has great colour reproduction and maybe slightly more fov than the rift. It is much clearer than the rift, but still suffers from an awful amount of god rays. I am going to try the lens upgrade as I have been informed that this will reduce the god rays substantially. i am also quite skeptical as to the quality or reliability of the Pimax and don't want to be without a decent headset should I be forced to send the Pimax back for repairs etc..
One thing I noticed is that I do not need my glasses for the Vive Pro, I use the insert from VR Optician and have them but they actually make the display blurry in the Vive Pro, whereas in the rift they are perfect..
Even the Vive pro will stress your PC quite a bit.. I am running I7 @ 5ghz, 32GB ram and a 2080ti and still cannot run the system at a constant 90fps at ultra settings.. Especially when there are a lot of ships around, CZ for example.. I prefer not to use the motion smoothing. I have also used the 3dmitigo settings to remove haze etc..
The colours are awesome, the 'feel' of space is much better than the rift, but there are still god rays and SDE
I will also say that Arizona Sunrise looks absolutely awesome on the Vive Pro... The colours are far more vibrant and vivid compared to the rift.. However, if this is someones first foray into VR I still recommend the rift... The software, especially dash, and the ease of use are far better than the steam setup. If Rift would release their software for use with the Vive pro I would purchase in a heat beat, it is that much better..
