  • Streamline some default configurations

Release Notes for 4.8.0

  • rework GUI, now uses several pages

  • workaround for eye position bug in Varjo Base <3.10, adapt defaults to 3.10

  • improve autocalibration settings for Varjo Aero IMU

  • include version number in installer, uninstaller

  • improved compiler flags to yield smaller binary

  • avoid buffering with IMU in VCP mode

  • restructure installation layout

Notes on the eye position bug in older versions of Varjo Base:

Varjo Base prior to version 3.10 misapplied a transformation to the user’s eye point, leading to suboptimal performance. The eye point would fluctuate approximately 15mm about the correct position. LPVR defaults to perform correctly with versions of Varjo Base past 3.10 that include the fix, but it can accommodate versions of Varjo Base with the bug as well. To do so, please open the Varjo Base configuration GUI on the System tab and then add patchPositionBug=true in the field labelled Additional Settings followed by clicking the “Submit” button. The setting will be remembered.
