well i didnt calibrate magnetism manually because i s till fail at that.
But yesterday i did update my pimax drivers from 1.2.57 to 126.96.36.199.
Didn't played anything after install, i just tried the magnetism calibration but failed so i posted on forum.
Hower i did follow your advice and used Z in steamvr and then launched. And as far as i can tell it dont have to press center every 1min, now maybe once in 7min or something. But its very little drift as far i can tell, very happy with this progress.
I also updated nvidia drivers to latest, both seem to work flawless , previouslyi had problems with not able to recognize hmd or not giving screen only black screen in steamvr etc.
So thanks, i was already happy with 4k now im very happy. Maybe i wont sell my 4k after all when i get my 8k.
