you need the version of steamvr beta 1.2.7 otherwise for now it does not work you will always have the same errors be careful not to run before msi afterburner even in the background by often problems with steamvr, then run msi afterburner only after viewing properly steamvr but never before msi

lately is also working with the 1.2.9 beta of steamvr in trinuspsvr 0.9.8b I have always left the selection of the display empty, and also all the settings in trinuspsvr advanced use only Ghostfixing and steam vr you start to icon of course, just wait a bit which calibrates the psvr, the important thing is that first imposed the display / psvr at 120hz as primary in Windows 10, then also for not having more problems with the 120hz I use a display emulator that emulates a monitor at 120hz this helps me to run all games even those that usually require to be performed on the screen of course if the first start of steamvr takes place in full screen and not icon will remain locked at 60hz causing problems out of sync with the psvr and then you have to close steamvr and Trinuspsvr and do the procedure again
