Using Pimax I attempted using OpenXR. First Problem, there is no selection for mouse under the select controllers. I do not use the VR controllers with VR. I use joystick, and mouse for selecting items to be clicked on.
The second of which might be on my end, game crashed in the first few minutes. I may have had a setting in Steam VR that needs to be changed in Pimax OpenXR. Some AH maps can be more demanding than Iracing on the CPU-GPU. As a side note some tracks in iracing are more demanding than most maps in AH.
