PimaxXR in Pimax Experiance slow compared to older PimaxXR Runtime

PimaxVR Software PE Discussion

Just a note that on testing in Il2 Using Pimax Experience version of OpenXR tends to lead me to a 15 to20% performance loss with Pimax Experience 1.36.01.01 compared to the old PimaxXR Runtime using PimaxXR Runtime Version -0,4.4

Is there a reason the Pimax Experience PimaxXR runtime is slower?

Do you mean the Pimax OpenXR runtime? The developers are working on optimizing its performance improvements and other features, such as the Quadview functionality.

I am seeing the same thing in DCS - I have a Pimax 8KX and was using the old pitool and PimaxXR v0.4.4. I upgraded to the current Pimax Play (using the imbedded PimaxXR) and it is 22% slower than the old PimaxXR in DCS. I can increase the FR by using the old OpenXR Tool kit with it’s turbo mode and upscaling.

In my tests, PimaxXR 0.4.5 + 1.29 PiPlay is ~10% faster than 1.38 PiPlay in Vulkan OpenXR in game called GTR2. So no go for me :frowning:

Also:

  • FFR does not work in Vulkan OpenXR, something I’d really like to see working in PiPlay. @PimaxQuorra - pretty please, could you guys add FFR in Vulkan OpenXR?
  • late PiPlay has weird issue - it stays in screensaver till I recenter (and sometimes only one eye leaves Screen Saver). Sad.

I’ll forward this to the dev team.

This is a known issue, they are working on a fix.
