I have already found the problem, well if it is. Changing the IPD offset in Pitool zooms in or out of the left eye image in the SteamVR desktop view. I have the extreme IPD mod done on my Pimax so the mechanical IPD is at minimum and is reporting 60mm. To adjust my vision to the extra lens shift (real 65mm) I have to put +3 IPD offset in Pitool.
@risa2000, the total IPD that I have set is not shown in HMDQ? that is, the 60mm of mechanical IPD + the +3 per eye of IPD offset. Can you tell that total IPD is coming to SteamVR or any other application? I have verified that FPSVR is useless, it reports the IPD that steamVR 63 has by default, if you add the line to steamvr.vrsettings:
and from there you change the IPD value, this will be the one that FPSVR shows but in reality there is no difference between for example 50 or 70. The image does not change, neither in the HMD nor in the SteamVR desktop view.
For all this, it is still not clear to me that IPD is the one that is being informed to the VR applications or games and therefore it is difficult to make corrections for each application and adjust a clear vision in each one of them.
