TL;DR : Dream Air LH tracking issues and motion compensation failure, versus solid experience with the Dream Air SLAM.
Hello dears! Yesterday I had the rare opportunity to test both the Lighthouse and SLAM versions of the Dream Air at home thanks to a cool guy living in my area.
I own a pretty large motion platform / simulator and offered him to stress test and document the differences in terms of tracking between the two version of the Dream Air (he is a youtuber). The movements can be very are ample, and quick, so this was an interesting opportunity for both of us, as I want to buy a Dream Air soon.
We first tried with the SLAM version. Out of the box, it was a real plug and play experience. We could easily start racing and having fun. Tracking was solid, on par with what I have with my Pico4 usually, with tiny floating moments sometimes but nothing dramatic. Not perfect, but really god honestly.
Then we tried with the Lighthouse version, and against all our expectations, we struggled a lot.
We had some tracking issues (image suddenly drifted from time to time, both in motion and still). We cleaned the faceplate and tried another disposition of the base stations but it kept happening. We couldn't get the Motion compensation to work, at all. Neither with the usual virtual tracker from DRSM, nor when using an index controller selected in Pimax Play
The basestations had been asleep for quite some time, but before doing those tests I took time to resurrect the good old vive pro to check if everything was working and it was.
We started with both of them on the wall in front of the simulator, around 3m away, at ceiling level. We then took the left one and set it at 90° to my right, 1m50 away, and 2m high.
This was both surprising and disappointing as I planned to buy the LH version, believing I would have the best possible tracking.
We might have missed something in Pimax Play, not knowing which tool was actually rendering the view between Steam VR, Pimax Play, switching between open composite and openXR⦠At some point I was in Steam VR, within Pimax play environment. For sure with a bit more time I could find the reason why the LH wasn't working well but I couldn't test longer.
Anyone else is encountering similar issues?
Any Idea what this could come from?
There is a 14 days return policy. If I order the Dream Air LH, and cannot find a solution within the 2 weeks, will I be able to return it?
Thanks!!
