I will try Dr Kaii's ED Profiler.
But i was just in multi crew whit a cmdr ho has the same issue whit the rift CV1.
But then he went up to the Rift S and the blur is gone. So is it the Rift CV1 ho has trouble whit ED...
Welcome to the amazing ED VR experience! =D
It's not that the CV1 has problems with ED, it's that the CV1 is very old and has a
much lower resolution than the Rift S. While some things are alright in the game, text generally won't be too clear. I started playing this on the CV1, and the difference between it and more modern headsets with higher resolutions like the Vive Pro (same res as the Rift S) was simply night and day.
One thing I will mention: for some reason many of the VR settings presets in this game turn on AntiAliasing, and will sometimes set it to SMAA. Turn that off!! ED's in-game AA utterly destroys the sharpness and quality of the picture in VR, and the simple act of just disabling it will make such a drastic improvement in the quality of your headset's image that you would hardly believe it.
Once you've done that and tried it out, if you still have some blurriness then I'd personally set SuperSampling to 1.0 or maybe 1.25, HMD quality to 1.0, then go into SteamVR settings and start upping the resolution there. It can't increase the actual resolution you're seeing beyond what the headset can physically render, but what it will do is generate the image at a higher res and then downscale to your headset, which does add
some clarity to the image. Doing this via SteamVR as opposed to in-game is a bit more performant.
Good luck!
