@deletedpimaxrep1 if you limited the FOV to 150 degrees, I believe it would not suffer from any warping at all. This is 1 reason why I brought up exchangeable lenses as a stretch goal. Because Steam VR was not designed for 200 degrees of FOV on HMDs, nor is the conventional optical path designed for such, (without angling the displays and figuring out the math,) it might be good to have the option for a lower FOV, I could be wrong though.
Steam VR and conventional optics I believe can handle 150 degrees without warping (as per Doc-Ok on reddit I believe.) There was a thread that mentioned this earlier,I will try and find it.
Couldn’t find the thread, BUT
@deletedpimaxrep1 you want your engineers to talk to Doc-OK. He’s a professor (I believe) at UC Davis and he can help you guys figure out what needs to be done to eliminate the warping distortion.
Here is a link to his reddit activity, and his youtube maybe you can reach him through this?
