I was hinting this could be the newest WMR anti-CA causing the blurriness as well, because when I see a copy of a purple EFIS text displaying in blue half letter size above, it is not CA but anti-CA software to me. And like you’re saying, if the filter is not aligned and calibrated for both position (L/R/U/D) and focal (eye/lens distance) it can’t work.
If I understand what you’re saying, the anti-CA center point is fixed and doesn’t move with the IPD adjustment? This might be a reason indeed.
If you want to try out some (I tried with no particular success), there are hidden registry settings you can adjust…
1 = enable | 0 = disable
1000 = 1.0 | 500 = 0.5 | 1500 = 1.5
NB: WMR reloads the values with the sensor! You can therefore remove headset, change value, put back headset and you can see immediate results!
I’ve otherwise set this one to 1 thinking it might delay loading WMR portal assets if WMR gets started by an application. I don’t know if this helps at all but if you do find it is giving you better start times or more VRam in FS2020, please share you experience back in this discussion!
There is also this one I didn’t try yet but which makes me wondering now that SteamVR 1.16.1 can project up to 6 frames, or whether this could help reducing the apparent lag when moving the head:
