Sorry for the delay in reply but the replacement headset, with no other changes (no software updates, etc.) , completely resolved the issue. I have to assume it was hardware related as the 90Hz mode works as expected and gains me some performance. I'll comment that the ticket submission/replacement/postage piece was pretty clunky but with a bit of patience and working with them, they made it all square up.

LtSpoon, FYI, after troubleshooting and sending logs to Pimax, they've asked me to return my headset for exchange. My issue sounded just like yours at 90Hz Upscale so I assume they've determined it was something in the hardware. -Soda

I have the same issue but with only the right eye. There is a horizontal "tear" effect in the picture and vertical "colored rain" streaks. I have an open support ticket with Pimax support and sent them a video of the effect (not sure Calvin if I provided you the ticket number if it might help). It's definitely related to the 90 Hz Upscale (Lab) mode as if I select a different refresh, it's fine. I updated to latest firmware/pimaxplay and no difference. It happens both in DCS and in the default "moonscape" background. Thoughts? Hoping to get this resolved as I suspect 90 Hz Upscale would provide the best visuals/performance combo but it's not working for me right now. -Soda
