So I am using the trial with FSX and I'm not sure the term but the warping seems off in that as I look around perspective changes as things get towards the edge of my fov. It feels KIND of like looking at the image on the desktop screen with a slight fish eye although in VR it's not nearly as bad. When just sitting still it feels pretty good but as you rotate your head the fisheye effect becomes notable.
This is really bad on the menue screen before the game loads in VR proper as the "waiting for simulator" box stretches all over and even tilting my head causes it to stretch as if the menu world is also rotating.
I tried the manual but didn't see where to configure this setting. Any pointers appreciated!
