The reason I asked is because using a widescreen resolution affects the T-cam position.
I've just introduced Positions Files to GP4 Central, which includes the T-cam position. My original plan was to assume everyone uses a widescreen setup now, but given the mixed results above, it seems that would only serve maybe 2/3 GP4 players.
The solution will be to make them dynamically generated based on whether you use a normal or widescreen setup. The responses here will help me test the most popular scenarios.
