I second this as well. Please test VORPX and tell us how it is!
My questions are:
Is the fov stretched to 200 degrees or is it close to native?
If it is stretched, does it effect your perception in the center of the screen while focusing on the middle?
What is the max fov possible?
Does vorpx even work?
Does the UI scaling feature work? (Ctrl + scroll down)
What is your performance with vorpx and what are your specs?
How does the game look in geometry mode vs non geometry? ( Z Adapative and non adaptive)
Does the FOV skewing on the periphery effect your impression of the game?
