This is one pager kneeboard for module of Yak-52 for DCS with main infos: power settings, radio freq., performance ect. Use "RShift+K" to show it (and navigate by "[" or "]" key).
The settings config file for Quad-views is about the best settings i've managed to dial-in when using Eye-tracking with the Pimax Crystal and PimaxXR/OpenXR-Toolkit/Quadviews
