Jittery unstable VR experience

I observed the shake in Crystal OG, only with DFR enabled in SU4 beta and Eye Tracking enabled in PimaxPlay. I returned to SU3 public release and there is no shake.

I moved my lighthouses to better cover where I sim. Switched back to lighthouses from inside out and at first it seemed a touch jitery, but after a minute it was butter smooth.

I believe it was just my video card getting crushed as per usual. lol. Once I was out of the more congested area it was super smooth for the rest of the flight. Could have also been the dynamic settings optimizing.

I can’t wait to see how good this is when I upgrade to a 5080 Super/Ti if it happens or a 5090 if not.

I’ll experiment with that today, though I think from testing so far that the stutter introduced by lowering render scale below 0.5 just adds another layer of shakiness on my Super, making it worse. I’ll find out today, turning FR on and off etc.

So strange, it has been working good for me in SU4. I’m running OG, 0.20 FR scale, TAA with 1.2x super sample.

I just tried again and no SU4 shaking issues with DFR. I was even looking for it this time.

I’ve just tested SU4 beta again too, both with the Pimax Crystal OG and the Super. In the Crystal OG I didn’t notice any obvious difference in turning FR on or off, apart from FPS of course. I then tried 0.5 and 0.25 render scale for comparison and again didn’t notice any shaking that was really obvious.

In the Super again turning DR on or off didn’t seem to make any difference, but I still have the unsteadiness due to it picking up head shake (or maybe worse headtracking), which the Crystal OG doesn’t do.

Perhaps a reinstall of the sim in SU4 beta might resolve the issue for stekusteku.

Hey all just wanted to give an update on my PCL head tracking jitters. Pimax support team recently sent me some customized SLAM files which I installed over the default files. Using latest Pimax Play software with the customized SLAM files appears to have significantly reduced the head tracking jitters I have been experiencing. Happy camper for now.

Still on the fence on whether to jump to a Super and specifically which module 50 PPD/57PPD/Ultrawide….

What are SLAM files?

Tough choice. I believe the OG is 42 and that looks quite good. At least they can be swapped if they really are interchangeable.

Don’t ask me what they actually do as I am no tech guy but you can check out the video i posted above on the PCL review for more details

OG Crystal is 35PPD. There were some 42PPD lenses made, but that fizzled out.
