Nope. Just received my Pimax a day ago and zero luck so far. Never expected this particular issue so didn't research specific incompatibilities between the Pimax drivers and AMD cards, but apparently it's a common problem. I have the exact same setup you do - 5700 XT and Pimax 5K +. Will have to return the Pimax, unfortunately, as the 5700 XT is beyond the Amazon return window and no way can I afford another new video card.
Anyone have a solution we don't know about yet?
Bought the pimax 5k headset and I am really disappointed
Error 10935, no way to get the pimax connected to amd gpu 5700xt.
Latest AMD driver installed, but does not work (19.9.3).
Tried 19.9.2 before. No way.
Despite of this issue with the pimax I am really happy with my 5700xt.
To my opinion these pimax headsets are “nvidia only”.
Maybe by design?
