Pimax 4k p3d big big issue

Dear all

What a drama. Lockheed Martin updated to V4.3 and we have a major problem with PIMAX.
There are black frames on the VR image which makes the all thiny unusable. This is the answer from P3D

"In Stereo and Single-Pass Stereo, we are using the stencil mesh to help performance.

"The stencil mesh is queried from the OpenVR driver for the headset.

It appears that PiMax is returning a bad stencil mesh. You should report this issue to PiMax."

What should we do as all Flysimmers will be desperate with PIMAX4K

Thanks for your help

Added pokes to your post.

Can you roll back the update? Abother thing to check is see if Vive/Oculus/Wmr users are reporting similar issues. Often devs will sidestep an issue.

Ie a user had a problem with getting a game controller to work. Due to him mentioning Pimax 4k headset; they’re response ignored his core issue siting “we have no support for your headset”

Thank you very much for the quick reply
I will in the meantime use flyinside with P3D (which does work with this version of P3D :hushed:)
P3Dv4.3 is bringing much better performance in VR than previous versions
(and PIMAX4K is performing very well)

I still have that Problem with Prepar3d V 4.4 and Pimax (or beta) …
Monomode is unusable - is there a workaround?

I have to add, i am using the 5k+

This topic might have info on this as it’s newer


i can confirm the white flickering … but my primary problem are the black bars through the picture…

I would post in the linked thread above as fellow prepar3d users might have some kind if solutions/workarounds.

Disable the “Hidden area mask” and “Paralell projection” for P3D
