Pimax Crystal 4312 x 5100 @ 120hz

PimaxXR OpexXR with Quad Views and Eyetracking enabled.

openRBRVR set for foveated rendering.

The eye tracked focal region jitters around with FR enabled. Unsure if there is a setup step I've missed due to it RBR running in 32bit but no other errors are seen other then the jittery focal box. VR works great with FR off. Any clues on this would be great. Thanks.

Hi.

This came up in Discord as well with Crystal Light's eye tracking. Unfortunately I don't have means to debug this as I don't have a device that would support eye tracking. I guess your best shot for now is to disable the eye tracking and use fixed foveated rendering instead.

EDIT: I take that back, Quad-Views-Foveated seems to support simulated eye tracking, perhaps I could reproduce the issue with it.

Cool. I've found my way to your discord but not posted anything there. RBR in VR is running well for me even without QV but it's really nice to see any support for QV and always hungry to test that out specially given it's need for any push to higher PPD and FOV headsets.
