I am working with the emulator on windows.

I have noticed something strange … when I create a regular 480x320 window , what I would call "a natural " landscape mode - everything displays fine.

On the other hand if I create a 320x480 window and then use PVRTMatrixPerspectiveFovRHF with bRotate set to true to emulate landscape mode , everything displays fine again but it seems that all objects appear to be much closer to the viewer.

It is really strange … I should get exactly the same display on both but rotating projection matrix gives me much smaller perceived FOV.

To really get the same display I have to adjust my FOV from 45 degrees to 65 degrees when rotating the matrix.

Am I missing something obvious here ?


Uhh … never mind … it was a stupid mistake on my part.
