In fact I found it "strange" at first, so I wonder if it was a problem with my TV, my console or a bug.
(But like it was never changed/fixed/modified since game release, I'm pretty confident that it was/is intended. In fact, you can't hardly miss it when you play^^)
* I did, that is what I am wondering about. Between when I first played and when I noticed it, I changed FOV, drivers, game patch, player level and maybe some of the graphic settings. But it seems unlikely those (except maybe the FOV) obscured it for me. But no big deal, thanks for showing me it had been in day one that was driving me a little crazy. Now when I play I hardly notice it anymore.
* Edit: for fun go back and read the numerous player posts on page one of this thread that were surprised to see it AFTER playing the game for a while:
"This just randomly happened to me. Closed the game for the night on 1.05. Fired it back up and bam, random curved mode."
So this was not just my opinion.
