It's the tweaking the FOV bit I don't want to do. If FOV is 87 on a 22" widescreen monitor, to get a realistic view and have the view move correctly for the way the car is turning, you need to be less than 30cm from the screen, which is very close. I want to run FOV at about 70 to 78 degrees on a 24" monitor so I can have my eyes a bit further from the screen.
If you set FOV to say 70 degrees with a widescreen monitor, does it squash the picture, or does it chop the top and bottom off (which might be OK, it's only sky and legs)?
Of course, you can get used to the FOV being "wrong", but I want to try and use GPL to help my driving in the real world, and I find it much easier to drive GPL like a real car if the view is realistic, ie if I get my eyes the right distance from the screen to match the FOV, because suddenly I feel like the car is actual turning round the corners.
As an aside, I was very careful when choosing a camera for in-car video to get one that would give a realistic FOV when I was watching it back - something else I learnt from GPL
