Hey everyone. Just registered today. This issue seems to have hit me over a patch during the last few weeks as well - the prior fixes (texture streaming, vsync in-game only, frame cap) no longer seem to work for me. I get the camera stutter of doom regardless of settings (only VERY LOW) resolves it on a GTX 770.
Sent in a support request with my Report.Zip, hopefully that helps get attention to the issue. On a GTX 770, I5-4670k, 8GB RAM, Windows 8.1 64-bit. Love the game, can't really enjoy it with the stutter mania on the camera so hopefully this will help us get a resolution!
