Causes and mitigations of judder

I'm encountering an issue where objects seem to jitter / flicker when I move. It's kind of like double vision. Or you could describe it as blurry edges.

 

After googling I discovered that this is called judder.

 

It happens more noticeably when I have a heavier scene. But it does happen a bit in light scenes as well. I did not notice a correlation with the performance metrics I'm tracking (FPS, stale frames, GPU usage, CPU usage).

 

I did not quite understand the previous discussion I read on the topic. I'm a novice VR developer. I'd appreciate some guidance on ways to identify the causes and mitigations for this issue.

 

I'm developing for PCVR using the Oculus Quest 2 headset.

 

(I posted this on other forums, I'll post back any solutions that I get)

It turns out measuring with the OVR Metrics Tool overlay was misleading.
I started using the performance HUD that can be enabled from the Oculus Debug Tool and I got much saner results.
