I think I got it. I used this exact post this time MRTV: Pimax IPD Tutorial - How To Set Pimax 8KX IPD Offset Correctly! No More Eyestrain! - #22 by blanes
While the base station wasn’t fully aligned physically vs the real life (a bit lower and more to the right side in VR) I still haven’t feel any strain in Beat Saber, Pop One, Space pirate trainer. I also turned PP on for Beat Saber and that weird unexplainable glare thing is gone. I can only faintly notice actual real glare of the lenses but it was similar in Valve Index so it doesn’t bother me.I set physical wheel IPD to 60,5 mm. Software: 0.7 right eye, -2.0 left eye, 0 for vertical offsets.
I did that with a thin face pad but I’m going to try and redo the setup of IPD for thicker pad since my eyebrows are touching the lenses which fogs them up at the top. If I dial IPD in with thicker pad then I can keep the headset. I will just 3d print the hinges for stable strap and use the Quest strap mod. Eventually I will also buy leather pad for the facial interface to deal better with sweating.
